Cybersecurity researchers have disclosed details of a Linux local privilege escalation (LPE) flaw that could allow an unprivileged local user to obtain root. The high-severity vulnerability tracked as CVE-2026-31431 (CVSS score: 7.8) has been codenamed Copy Fail by Xint.io and Theori. "An unprivileged local user can write four controlled bytes into the page cache of any readable file on a Linux system, and use that to gain root," the vulnerability research team at Xint.io and Theori said . At its core, the vulnerability stems from a logic flaw in the Linux kernel's cryptographic subsystem, specifically within the algif_aead module. The issue was introduced in a source code commit made in August 2017. Successful exploitation of the shortcoming could allow a simple 732-byte Python script to edit a setuid binary and obtain root on essentially all Linux distributions shipped since 2017, including Amazon Linux, RHEL, SUSE, and Ubuntu. The Python exploit involves four ...

Google has addressed a maximum severity security flaw in Gemini CLI -- the "@google/gemini-cli" npm package and the "google-github-actions/run-gemini-cli" GitHub Actions workflow -- that could have allowed attackers to execute arbitrary commands on host systems. "The vulnerability allowed an unprivileged external attacker to force their own malicious content to load as Gemini configuration," Novee Security said in a Wednesday report. "This triggered command execution directly on the host system, bypassing security before the agent’s sandbox even initialized." The shortcoming, which does not have a CVE identifier, carries a CVSS score of 10.0. It affects the following versions - @google/gemini-cli < 0.39.1 @google/gemini-cli < 0.40.0-preview.3 google-github-actions/run-gemini-cli < 0.1.22 In its advisory published last week, Google said the impact is limited to workflows using Gemini CLI in headless mode, adding that any use of...

Cybersecurity researchers are sounding the alarm about a new supply chain attack campaign targeting SAP-related npm Packages with credential-stealing malware. According to reports from Aikido Security , Onapsis , OX Security ,  SafeDep , Socket , StepSecurity , and Google-owned Wiz , the campaign – calling itself the Mini  Shai-Hulud – has affected the following packages associated with SAP's JavaScript and cloud application development ecosystem - mbt@1.2.48 @cap-js/db-service@2.10.1 @cap-js/postgres@2.2.2 @cap-js/sqlite@2.2.2 "The affected versions introduced new installation-time behavior that was not previously part of these packages' expected functionality," Socket said. "The compromised releases added a preinstall script that acts as a runtime bootstrapper, downloading a platform-specific Bun ZIP from GitHub Releases, extracting it, and immediately executing the extracted Bun binary." "The implementation also follows HTTP redirects wi...

Cybersecurity researchers have discovered malicious code in an npm package after a malicious package as a dependency to the project by Anthropic's Claude Opus large language model (LLM). The package in question is " @validate-sdk/v2 ," which is listed on npm as a utility software development kit (SDK) for hashing, validation, encoding/decoding, and secure random generation. However, its real functionality is to plunder sensitive secrets from the compromised environment. The package, which shows signs of being vibe-coded using generative artificial intelligence (AI), was first uploaded to the repository in October 2025. The malware campaign has been codenamed PromptMink by ReversingLabs, which linked the activity as part of a broader campaign mounted by the North Korean threat actor known as Famous Chollima (aka Shifty Corsair), which is behind the long-running Contagious Interview campaign and the fraudulent IT Worker scam . "The new malware campaign [...] inv...

In February 2026, researchers uncovered a shift that completely changed the game: threat actors are now using custom AI setups to automate attacks directly into the kill chain. We aren't just talking about AI writing better phishing emails anymore. We’re talking about autonomous agents mapping Active Directory and seizing Domain Admin credentials in minutes. The problem? Most defensive workflows still look like this: your CTI team finds a threat, they pass it to the Red Team to test, and eventually, the results reach the Blue Team for patching. This process is full of friction, silos, and delays. The reality is simple: You cannot fight an AI adversary moving at machine speed when your defense moves at the speed of a calendar invite. To bridge this gap, we’re hosting a technical deep dive with the team at Picus Security to unveil a new defensive paradigm: Autonomous Exposure Validation .

Every security team has a version of the same story. The quarter ends with hundreds of vulnerabilities closed. The dashboards are bursting with green. Then someone in a leadership meeting asks: "So, are we actually safer now?" Crickets. The room goes quiet because an honest answer requires context – which is something that patch counts and CVSS scores were never designed to provide. Exposure management was created to provide this context - to bridge the gap between remediation efforts and actual risk reduction. The market has responded with a flood of platforms claiming to deliver it.  Yet the question security leaders are asking is: which exposure management platform actually does provide it? In this article, I’ll break down the four dominant approaches to exposure management, explain what each one can and can't deliver, and lay out five evaluation criteria that help you separate platforms built to reduce risk to your unique business and environment from platforms ...

cPanel has released security updates to address a security issue impacting various authentication paths that could allow an attacker to obtain access to the control panel software. The problem affects all currently supported versions of cPanel and WebHost Manager (WHM), according to an alert published by WebPros on Tuesday. It does not have an official identifier. The issue has been addressed in the following versions - 11.86.0.41 11.110.0.97 11.118.0.63 11.126.0.54 11.130.0.19 11.132.0.29 11.136.0.5 11.134.0.20 "If your server is not running a supported version of cPanel that is eligible for this update, it is highly recommended that you work toward updating your server as soon as possible, as it may also be affected," cPanel noted. While cPanel did not share any details about the vulnerability, web hosting and domain registration company Namecheap disclosed that it "relates to an authentication login exploit that could allow unauthorized access to the ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added two security flaws impacting ConnectWise ScreenConnect and Microsoft Windows to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerabilities are listed below - CVE-2024-1708 (CVSS score: 8.4) - A path traversal vulnerability in  ConnectWise ScreenConnect that could allow an attacker to execute remote code or directly impact confidential data and critical systems. (Fixed in February 2024) CVE-2026-32202 (CVSS score: 4.3) - A protection mechanism failure vulnerability in  Microsoft Windows Shell that could allow an unauthorized attacker to perform spoofing over a network. (Fixed in April 2026) The addition of CVE-2026-32202 to the KEV catalog comes a day after Microsoft updated its advisory  for the flaw to acknowledge it had come under active exploitation. Although Microsoft has not disclosed the nature of the attacks weaponizi...

In yet another instance of threat actors quickly jumping on the exploitation bandwagon, a newly disclosed critical security flaw in BerriAI's LiteLLM Python package has come under active exploitation in the wild within 36 hours of the bug becoming public knowledge. The vulnerability, tracked as CVE-2026-42208 (CVSS score: 9.3), is an SQL injection that could be exploited to modify the underlying LiteLLM proxy database. "A database query used during proxy API key checks mixed the caller-supplied key value into the query text instead of passing it as a separate parameter," LiteLLM maintainers said in an alert last week. "An unauthenticated attacker could send a specially crafted Authorization header to any LLM API route (for example, POST /chat/completions) and reach this query through the proxy's error-handling path. An attacker could read data from the proxy's database and may be able to modify it, leading to unauthorized access to the proxy and the c...

Cybersecurity researchers have disclosed details of a critical security vulnerability impacting GitHub.com and GitHub Enterprise Server that could allow an authenticated user to obtain remote code execution with a single "git push" command. The flaw, tracked as CVE-2026-3854 (CVSS score: 8.7), is a case of command injection that could allow an attacker with push access to a repository to achieve remote code execution on the instance. "During a git push operation, user-supplied push option values were not properly sanitized before being included in internal service headers," per a GitHub advisory for the vulnerability. "Because the internal header format used a delimiter character that could also appear in user input, an attacker could inject additional metadata fields through crafted push option values." Google-owned cloud security firm Wiz has been credited with discovering and reporting the issue on March 4, 2026, with GitHub validating and deployi...

A cybercrime group of Brazilian origin has resurfaced after more than three years to orchestrate a campaign that targets Minecraft players with a new stealer called LofyStealer (aka GrabBot). "The malware disguises itself as a Minecraft hack called 'Slinky,'" Brazil-based cybersecurity company ZenoX said in a technical report. "It uses the official game icon to induce voluntary execution, exploiting the trust of young users in the gaming scene." The activity has been attributed with high confidence to a threat actor known as LofyGang , which was observed leveraging typosquatted packages on the npm registry to push stealer malware in 2022, specifically with an intent to siphon credit card data and user accounts associated with Discord Nitro, gaming, and streaming services. The group, believed to be active since late 2021, advertises their tools and services on platforms like GitHub and YouTube, while also contributing to an underground hacking communit...

Threat hunters are warning that the cybercriminal operation known as VECT 2.0 acts more like a wiper than a ransomware due to a critical flaw in its encryption implementation across Windows, Linux, and ESXi variants that renders recovery impossible even for the threat actors. The fact that VECT's locker permanently destroys large files rather than encrypting them means even victims who opt to pay the ransom cannot get their data back, as the decryption keys are discarded by the malware during the time encryption occurs. "VECT is being marketed as ransomware, but for any file over 131KB – which is most of what enterprises actually care about – it functions as a data destruction tool," Eli Smadja, group manager at Check Point Research, said in a statement shared with The Hacker News. "CISOs need to understand that in a VECT incident, paying is not a recovery strategy. There is no decrypter that can be handed over, not because the attackers are unwilling, but beca...
