A GitHub issue opened by an account with no repository privileges was enough to execute code on the CI runners behind Anthropic's and Google's own coding-agent repositories. On OpenAI's, it was enough to hijack the next agent run. Novee Security ran the attack against each vendor's agent in the configuration that the vendor ships by default, and presented the work at Black Hat USA on August 5. Two CVEs came out of it. Both are patched. Gemini CLI carries the worst of the two. CVE-2026-12537 (CVSS 4 score: 10.0) is an OS command injection in the container launcher, reached through a crafted .gemini/.env file, which lets an unprivileged attacker run code on the host of a headless CI platform before the sandbox starts. It is fixed in Gemini CLI 0.39.1 and run-gemini-cli 0.1.22. In Claude Code, CVE-2026-54316 turned Hugging Face's public download counter into an exfiltration channel that leaked an API key one character at a time, and is fixed in 2.1.163. Every ...

A newly patched security flaw impacting on-premise versions of JetBrains TeamCity has come under active exploitation in the wild , according to the U.S. Cybersecurity and Infrastructure Security Agency (CISA). The vulnerability in question is CVE-2026-63077 (CVSS score: 9.8), a case of deserialization of untrusted data that could allow an unauthenticated attacker with access to a TeamCity server to bypass authentication checks and execute arbitrary operating system commands with the privileges of the TeamCity server process. "JetBrains TeamCity contains a deserialization of untrusted data vulnerability that could allow unauthenticated remote code execution via the agent polling protocol," CISA said . According to JetBrains, the vulnerability can be exploited by an unauthenticated attacker via the TeamCity agent polling protocol to sidestep authentication checks and execute arbitrary operating system commands. The exact impact varies depending on the privileges grant...

A cluster of 77 extensions on the Open VSX marketplace has been found to impersonate legitimate developer tools while transmitting information about the systems and development environments on which they were installed. The "evil twin" extensions were uploaded to the repository between July 26 and August 1, 2026, according to Manifold Security. The packages have been removed from Open VSX as of August 3, 2026. "In most of the packages it sends little more than the machine's hostname," security researchers Ax Sharma and Cody Nash said . "In nineteen of them it sends a detailed description of the machine, the repository open in the editor, and the CI system the editor is running inside." Of the identified extensions, 58 have been described as lightweight tools designed to exfiltrate the hostname and, in some cases, the workspace folder name or editor version. The rest are reconnaissance payloads that transmit the developer-related information: l...

A credential-stealing npm worm that first appeared in keyv@6.0.0 spread beyond the Keyv and Cacheable namespaces into hundreds of packages across multiple organizations on August 4, 2026. SafeDep verified 353 poisoned versions across 79 package names in the npm registry. Its monitoring put the wider footprint at 442 versions across 353 names, while Aikido later reported at least 868 packages across 1,381 versions. Neither broader total was independently reproducible from a complete public list at the reporting cutoff. The malicious release used a preinstall script to run a credential-stealing bundle inside developer and continuous integration (CI) environments. SafeDep and Socket say it can harvest repository, package registry, cloud and private-key material, then use available npm publishing access to poison more packages. The Keyv repository also retained separate Claude Code and Visual Studio Code (VS Code) hooks that can execute the payload once a user trusts the workspace...

Google deleted three AI agent workflows from its Agent Development Kit (ADK) Python repository. Pillar Security showed that a public GitHub issue could manipulate a triage agent into triggering a privileged code-fixing agent. The researchers said the public agent could be prompt-injected into posting /adk-issue-fix as adk-bot . They identified the bot as a collaborator, so that comment satisfied the privileged workflow's owner, member, or collaborator gate. The trusted bot identity became the authorization bridge. The team demonstrated arbitrary code execution on the continuous integration (CI) runner and exfiltration of the bot personal access token (PAT). The privileged job also held a Google API key and a Google Cloud service-account credential. Its researcher-controlled proof-of-concept attacks do not identify in-the-wild exploitation or a compromised ADK release. The exposed component was the repository automation, not a flaw in the distributed ADK Python package. Fo...

JetBrains is urging customers of on-premise versions of TeamCity to update to the latest version following the discovery of a critical security issue that could result in arbitrary code execution. The vulnerability, assigned CVE-2026-63077 (CVSS score: 9.8), affects all TeamCity On-Premises versions. It has been addressed in versions 2025.11.7 and 2026.1.3. TeamCity Cloud instances have already been updated. JetBrains has credited Antoni Tremblay with discovering and reporting the flaw on July 10, 2026. "If exploited, this flaw may enable an unauthenticated attacker with HTTP(S) access to a TeamCity server to bypass authentication checks and execute arbitrary operating system commands with the privileges of the TeamCity server process," JetBrains said. The flaw allows unauthenticated remote code execution via the agent polling protocol to sidestep authentication checks and achieve command execution. Depending on the privileges granted to the TeamCity server process, ...

GitHub has announced a new cooldown mechanism in Dependabot, allowing the tool to wait at least three days after a release is published before opening a pull request. "The cooldown configuration option in the dependabot.yml still controls the behavior, though, so you can choose a different cooldown parameter that fits your project," the Microsoft-owned subsidiary said . According to GitHub, the three-day cooldown default only applies to version updates, which are designed to keep software dependencies up-to-date. Security updates will continue to be pushed right away, permitting Dependabot to issue an alert and open a pull request to move the project to the patched version. With this update, the idea is to handle scenarios where a threat actor manages to push a poisoned version of a popular package, which then gets quickly pulled by downstream projects before that version is yanked from the registry. Although such trojanized packages are short-lived, the time period fo...

Security researchers at  depthfirst published working exploit code on July 24 for a GitLab flaw that GitLab patched six weeks earlier, on June 10. It runs commands as git on any self-managed 18.11.3 server that has not taken the update. Any authenticated user who can push to a project can run it. The attacker commits a crafted Jupyter notebook and opens its commit diff, which leaks a heap pointer. Enough of those and an automated probe can locate the libraries in memory. Two more notebooks then fire the payload. No administrator rights, no CI or runner access, no victim interaction, no access to anyone else's project. GitLab did not file the fix as a security fix. A review by The Hacker News found the Oj 3.17.3 bump listed under bug fixes in the June 10 patch release , not in the security-fix table. There is no CVE, no CVSS score, and no mention of the notebook-diff chain. Operators who triaged that release against the security table had no reason to treat it as urgent. ...

Four compromised npm packages in the @asyncapi namespace have been observed distributing a multi-stage botnet loader, according to findings from OX Security , SafeDep , Socket , and StepSecurity . The affected packages are listed below - @asyncapi/generator-helpers@1.1.1 @asyncapi/generator-components@0.7.1 @asyncapi/generator@3.3.1 @asyncapi/specs(v6.11.2, v6.11.2-alpha.1) "The compromised packages deploy an obfuscated first-stage payload that downloads an encrypted second-stage payload, identified as Miasma, from IPFS," Socket said. The poisoned packages ship a hidden JavaScript implant, with each of them containing an injected source file that decodes to the same second-stage downloader. Unlike previous iterations that leveraged install hooks to trigger the execution of a JavaScript payload, the malicious code in this case is run when the infected module is loaded by Node.js, after which it launches a detached background node that downloads and execute...

The jscrambler npm package was compromised, and simply installing its 8.14.0 release runs an infostealer on your machine. Published on July 11, 2026, the malicious version carries a preinstall hook that drops and executes a native binary, one build each for Windows, macOS, and Linux. Socket flagged the release  six minutes after it was published . If you or one of your build systems pulled it in that window, the payload has already run with whatever access your install process had. None of this is in the prior release, 8.13.0.  The package diff  shows two new files under dist/: setup.js, a small loader, and intro.js. Despite the name, intro.js is not JavaScript but a roughly 7.8MB container packing three gzip-compressed native binaries, one each for Linux, Windows, and macOS. On install, setup.js picks the binary for the host operating system, writes it under a random name in the system temp directory...

A public issue can trick GitHub Agentic Workflows into leaking the contents of an organization's private repositories, researchers at Noma Security have shown. The attacker needs only to open a normal-looking issue on a public repository, with no stolen credentials and no access to the organization. If that organization has given the agent read access across its repositories, private ones included, the issue can steer it into pulling private contents into a public comment. Noma calls the technique GitLost . The target is GitHub Agentic Workflows , a feature now in public preview that GitHub launched in February. Instead of writing automation scripts, you write instructions to an AI agent in plain English in a Markdown file. The agent reads issues and pull requests, runs tools, and replies on its own. It can be powered by GitHub Copilot, Anthropic's Claude, Google Gemini, or OpenAI Codex. Workflows are read-only by default, but an organization can hand one a token with...

Cybersecurity researchers have flagged a new class of CI/CD workflow weakness that allows attackers to hijack workflows and compromise open-source supply chains. The "critical exploitable pattern" has been codenamed Cordyceps by Novee Security. The issue can allow full attacker control of repositories at dozens of the largest organizations worldwide, including Microsoft, Google, Apache, and Cloudflare. "The flaw is exploitable by any unauthenticated user," Elad Meged, founding engineer and security researcher at Novee Security, said . "No org membership or special privileges; a free account is enough to forge approvals, push code, or steal credentials." The penetration-testing company's scan of about 30,000 high-impact repositories has revealed more than 300 to be fully exploitable, enabling attacker-controlled code execution, credential theft, and supply chain compromise, which can have severe downstream impacts. The core of the problem tri...

Bitwarden CLI , the command-line interface for the password manager Bitwarden, has reportedly been compromised as part of a newly discovered and ongoing Checkmarx supply chain campaign , according to findings from JFrog and Socket. "The affected package version appears to be @bitwarden/cli@2026.4.0 , and the malicious code was published in 'bw1.js,' a file included in the package contents," the application security company said . "The attack appears to have leveraged a compromised GitHub Action in Bitwarden's CI/CD pipeline, consistent with the pattern seen across other affected repositories in this campaign." In a post on X, JFrog said the rogue version of the package "steals GitHub/npm tokens, .ssh, .env, shell history, GitHub Actions and cloud secrets, then exfiltrates the data to private domains and as GitHub commits." Specifically, the malicious code is executed by means of a preinstall hook, resulting in the theft of local, CI, Git...

The popular HTTP client known as Axios has suffered a supply chain attack after two newly published versions of the npm package introduced a malicious dependency that delivers a trojan capable of targeting Windows, macOS, and Linux systems. Versions 1.14.1 and 0.30.4 of Axios have been found to inject " plain-crypto-js " version 4.2.1 as a fake dependency. According to StepSecurity, the two versions were published using the compromised npm credentials of the primary Axios maintainer ("jasonsaayman"), allowing the attackers to bypass the project's GitHub Actions CI/CD pipeline. "Its sole purpose is to execute a postinstall script that acts as a cross-platform remote access trojan (RAT) dropper, targeting macOS, Windows, and Linux," security researcher Ashish Kurmi said . "The dropper contacts a live command and control server and delivers platform-specific second-stage payloads. After execution, the malware deletes itself and replaces its own...

TeamPCP, the threat actor behind the supply chain attack targeting Trivy , KICS , and litellm , has now compromised the telnyx Python package by pushing two malicious versions to steal sensitive data. The two versions, 4.87.1 and 4.87.2, published to the Python Package Index (PyPI) repository on March 27, 2026, concealed their credential harvesting capabilities within a .WAV file. Users are recommended to downgrade to version 4.87.0 immediately. The PyPI project is currently quarantined. Various reports from Aikido , Endor Labs , JFrog ,  Ossprey Security , SafeDep , Socket , and StepSecurity indicate the malicious code is injected into "telnyx/_client.py," causing it to be invoked when the package is imported into a Python application. The malware is designed to target Windows, Linux, and macOS systems. "Our analysis reveals a three-stage runtime attack chain on Linux/macOS consisting of delivery via audio steganography, in-memory execution of a data harvester, ...

TeamPCP , the threat actor behind the recent compromises of Trivy and KICS, has now compromised a popular Python package named litellm , pushing two malicious versions containing a credential harvester, a Kubernetes lateral movement toolkit, and a persistent backdoor. Multiple security vendors, including Endor Labs and JFrog , revealed that litellm versions 1.82.7 and 1.82.8 were published on March 24, 2026, likely stemming from the package's use of Trivy in their CI/CD workflow. Both the backdoored versions have since been removed from PyPI. "The payload is a three-stage attack: a credential harvester sweeping SSH keys, cloud credentials, Kubernetes secrets, cryptocurrency wallets, and .env files; a Kubernetes lateral movement toolkit deploying privileged pods to every node; and a persistent systemd backdoor (sysmon.service) polling 'checkmarx[.]zone/raw' for additional binaries," Endor Labs researcher Kiran Raj said. As observed in previous cases, the ha...

Two more GitHub Actions workflows have become the latest to be compromised by credential-stealing malware by a threat actor known as TeamPCP, the cloud-native cybercriminal operation also behind the Trivy supply chain attack . The workflows, both maintained by the supply chain security company Checkmarx, are listed below - checkmarx/ast-github-action checkmarx/kics-github-action Cloud security company Sysdig said it observed an identical credential stealer as the one used in TeamPCP's operations targeting Aqua Security's Trivy vulnerability scanner and its associated GitHub Actions, about four days after the breach on March 19, 2026. The Trivy supply chain compromise is being tracked under the CVE identifier CVE-2026-33634 (CVSS score: 9.4). "This suggests that the stolen credentials from the Trivy compromise were used to poison additional actions in affected repositories," Sysdig said . The stealer, referred to as "TeamPCP Cloud stealer," is desig...

Cybersecurity researchers have discovered five malicious Rust crates that masquerade as time-related utilities to transmit .env file data to the threat actors. The Rust packages, published to crates.io, are listed below - chrono_anchor dnp3times time_calibrator time_calibrators time-sync The crates, per Socket, impersonate timeapi.io and were published between late February and early March 2026. It's assessed to be the work of a single threat actor based on the use of the same exfiltration methodology and the lookalike domain ("timeapis[.]io") to stash the stolen data. "Although the crates pose as local time utilities, their core behavior is credential and secret theft," security researcher Kirill Boychenko said . "They attempt to collect sensitive data from developer environments, most notably .env files, and exfiltrate it to threat actor-controlled infrastructure." While four of the aforementioned packages exhibit fairly straightforward ...

The second wave of the Shai-Hulud supply chain attack has spilled over to the Maven ecosystem after compromising more than 830 packages in the npm registry. The Socket Research Team said it identified a Maven Central package named org.mvnpm:posthog-node:4.18.1 that embeds the same two components associated with Sha1-Hulud: the "setup_bun.js" loader and the main payload "bun_environment.js." The company told The Hacker News that org.mvnpm:posthog-node:4.18.1 was the only Java package identified so far. "This means the PostHog project has compromised releases in both the JavaScript/npm and Java/Maven ecosystems, driven by the same Shai Hulud v2 payload," the cybersecurity company said in a Tuesday update. It's worth noting that the Maven Central package is not published by PostHog itself. Rather, the "org.mvnpm" coordinates are generated via an automated mvnpm process that rebuilds npm packages as Maven artifacts. The Maven Central said...

The cascading supply chain attack that initially targeted Coinbase before becoming more widespread to single out users of the "tj-actions/changed-files" GitHub Action has been traced further back to the theft of a personal access token ( PAT ) related to SpotBugs. "The attackers obtained initial access by taking advantage of the GitHub Actions workflow of SpotBugs, a popular open-source tool for static analysis of bugs in code," Palo Alto Networks Unit 42 said in an update this week. "This enabled the attackers to move laterally between SpotBugs repositories, until obtaining access to reviewdog." There is evidence to suggest that the malicious activity began as far back as late November 2024, although the attack against Coinbase did not take place until March 2025. Unit 42 said its investigation began with the knowledge that reviewdog's GitHub Action was compromised due to a leaked PAT associated with the project's maintainer. This subsequen...
