CISA Adds Actively Exploited SolarWinds Serv-U DoS Flaw to KEV Catalog

CISA Adds Actively Exploited SolarWinds Serv-U DoS Flaw to KEV Catalog

Jun 06, 2026 Vulnerability / Patch Management
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a high-severity security flaw impacting SolarWinds Serv-U multi-protocol file server software to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2026-28318 (CVSS score: 7.5), is a denial-of-service (DoS) bug that causes the service to crash under certain conditions. CISA described it as an uncontrolled resource consumption vulnerability that results in a DoS condition. "SolarWinds Serv-U is susceptible to specially crafted POST requests that crash the Serv-U service without authentication using Content-Encoding: deflate," SolarWinds said in an advisory released earlier this week. The issue has been addressed in SolarWinds Serv-U version 15.5.4 HF1. As mitigations, it's advised to limit access to known addresses and block any request containing "content-encoding" since the vulnerable service does not r...
AI Agent Uncovers 21 Zero-Days in FFmpeg; Chrome Patches Record 429 Bugs

AI Agent Uncovers 21 Zero-Days in FFmpeg; Chrome Patches Record 429 Bugs

Jun 06, 2026 Vulnerability / Endpoint Security
Two things landed within days of each other this week. A security startup reported 21 previously unknown vulnerabilities in FFmpeg, the media library inside almost everything that touches video, all of them found by an autonomous AI agent. The same week, Google shipped Chrome 149 with patches for 429 security bugs, the most ever in a single release. Only the FFmpeg bugs were found by AI. Chrome's record landed after Google overhauled its bounty program to cope with a flood of AI-generated reports. The mechanisms differ, but the pressure is the same: AI is putting more vulnerabilities in front of the people who have to deal with them, and faster than before. The FFmpeg findings come from depthfirst , whose autonomous security agent scanned the project's roughly 1.5 million lines of C and produced 21 confirmed zero-days, each with a reproducible proof-of-concept input. The company puts the cost of the run at around $1,000. Several of the bugs had been latent for 15 to 2...

Hackers Exploit Critical Everest Forms Pro WordPress Plugin Flaw to Take Over Sites

Hackers Exploit Critical Everest Forms Pro WordPress Plugin Flaw to Take Over Sites

Jun 05, 2026 Web Security / Vulnerability
Threat actors are actively exploiting a critical security flaw in Everest Forms Pro, a WordPress plugin with about 4,000 active installations, to execute arbitrary code, leading to a complete site compromise. The vulnerability in question is CVE-2026-3300 (CVSS score: 9.8), a remote code execution bug impacting all versions of the plugin up to, and including, 1.9.12. A patch for the flaw was released on March 18, 2026, with version 1.9.13. "This is due to the Calculation Addon's process_filter() function concatenating user-submitted form field values into a PHP code string without proper escaping before passing it to eval()," Wordfence said . "The sanitize_text_field() function applied to input does not escape single quotes or other PHP code context characters. This makes it possible for unauthenticated attackers to inject and execute arbitrary PHP code on the server by submitting a crafted value in any string-type form field (text, email, URL, select, radio) ...
Cisco Patches CVE-2026-20230 in Unified CM as Exploit Code Goes Public

Cisco Patches CVE-2026-20230 in Unified CM as Exploit Code Goes Public

Jun 04, 2026 Vulnerability / Network Security
Cisco has patched a bug in Unified Communications Manager that lets an unauthenticated attacker on the network write files to the box and, from there, climb to root. It is tracked as CVE-2026-20230 , and proof-of-concept exploit code is already public. Cisco's PSIRT says it has not seen the flaw used in attacks yet. The PoC shortens that runway. The flaw is a server-side request forgery. Unified CM and its Session Management Edition fail to validate certain HTTP requests properly, so a crafted request can push the server into writing arbitrary files onto the underlying OS. Those files are the foothold. Cisco says they can be used later to escalate to root, the top privilege on the system. That two-step is why the score and the rating disagree. The CVSS base is 8.6: it scores the file write (an integrity-only impact, no confidentiality or availability loss) but not the root escalation that follows. Cisco rated the advisory Critical anyway, since the end state is full root. ...
Claude Code GitHub Action Flaw Let One Malicious Issue Hijack Repositories

Claude Code GitHub Action Flaw Let One Malicious Issue Hijack Repositories

Jun 04, 2026 Vulnerability / AI Security
A security researcher found a flaw in Anthropic's Claude Code GitHub Action that let an attacker take over vulnerable public repositories running it, with nothing more than a single opened GitHub issue. Because Anthropic's own action repo used the same workflow, a working attack could have pushed malicious code into the action itself and onto the projects downstream that pull it. RyotaK of GMO Flatt Security reported the core bypass to Anthropic in January, and Anthropic fixed it within four days , with further hardening through the spring; the fixes are in claude-code-action v1.0.94. Anthropic rated the issues 7.8 under CVSS v4.0 and paid a bug bounty. Claude Code GitHub Actions drops Claude into CI/CD pipelines to triage issues, slap on labels, review pull requests, or run slash commands. By default, the workflow gets read and write access to a repo's code, issues, pull requests, discussions, and workflow files. Because those permissions are broad, the action is su...

WhatsApp, Slack Notifications Could Hijack Google Gemini on Android

WhatsApp, Slack Notifications Could Hijack Google Gemini on Android

Jun 03, 2026 Vulnerability / Artificial Intelligence
A single poisoned notification from WhatsApp, Slack, SMS, Signal, Instagram, or Messenger could have hijacked Google Gemini's voice assistant on Android and made it open a victim's connected windows, fake a message from their boss, push the phone into a Zoom call, or quietly poison its long-term memory. No malicious app on the phone is required. The assistant just had to treat a hostile notification as useful context. The research, published by SafeBreach's Or Yair, follows the team's earlier " Invitation Is All You Need " work, which pulled off similar tricks through malicious Google Calendar invites. After that, Google hardened Gemini against indirect prompt injection. Yair found a way around the new defenses. Google has since patched it, SafeBreach lists no CVE for the issue, and there is no evidence that the technique was ever used in the wild. On Android, Gemini's Utilities feature can read and reply to your notifications, including ones ...
Microsoft Fixes One-Click GitHub Dev Attack That Let Attackers Steal OAuth Tokens

Microsoft Fixes One-Click GitHub Dev Attack That Let Attackers Steal OAuth Tokens

Jun 03, 2026 Vulnerability / Software Development
Cybersecurity researchers have disclosed a one-click attack via Microsoft Visual Studio Code (VS Code) that makes it possible to steal a user's GitHub token. "Just by clicking a link, it's possible for an attacker to steal a GitHub token that can read and write to your repos, including private ones," security researcher Ammar Askar said . GitHub supports a feature called GitHub.dev that runs as a lightweight web-based source code editor in the web browser's sandbox by launching a VS Code environment. It allows users to send pull requests and make commits. "This functionality is achieved by github.com POSTing over an OAuth token to github.dev that allows it to interact with GitHub on your behalf," Askar said. "The token is not scoped to the particular repo you interacted with, meaning it has full access to every other repo that you have access to." In a nutshell, the vulnerability allows attackers to install malicious VS Code extensio...
Autonomous AI Tool Finds 2-Year-Old RCE Flaw in Redis (CVE-2026-23479)

Autonomous AI Tool Finds 2-Year-Old RCE Flaw in Redis (CVE-2026-23479)

Jun 03, 2026 Vulnerability / Cloud Security
Redis has patched a use-after-free in its blocking-client code that lets an authenticated user run arbitrary OS commands on the machine hosting the database. The flaw was found by an autonomous AI tool built to hunt bugs in large codebases. Tracked as CVE-2026-23479 , the flaw was introduced in Redis 7.2.0 and remained in every stable branch until the May 5 fixes, unnoticed for over two years. NVD rates it 8.8 under CVSS 3.1; Redis lists it as 7.7 under CVSS 4.0. It was reported by Team Xint Code, and a complete technical  write-up is now public. The cloud footprint makes this worse. Wiz's analysis, published with the exploit writeup, puts Redis in a large majority of cloud environments, with most of those instances running without a password. The exploit needs an authenticated session, but in a default deployment, the default user already holds every privilege the chain requires. The flaw lives in unblockClientOnKey() in src/blocked.c , which fires when a key event wakes ...

CISA Adds Exploited Magento RCE Flaw CVE-2026-45247 to KEV Catalog

Jun 03, 2026 Web Security / Vulnerability
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a critical flaw impacting Mirasvit Cache Warmer, a popular Magento full-page cache extension, to its Known Exploited Vulnerabilities (KEV) catalog, following reports of active exploitation in the wild. The vulnerability, tracked as CVE-2026-45247 (CVSS score: 9.8), is a case of deserialization of untrusted data that could be exploited to execute arbitrary PHP code on an affected server. "Mirasvit Full Page Cache Warmer contains a deserialization of untrusted data vulnerability that could allow unauthenticated attackers to achieve remote code execution by supplying a crafted serialized PHP object in the CacheWarmer cookie," CISA said . The shortcoming impacts all versions of the extension prior to version 1.11.12. Patches for the were released on May 25, 2026. The addition of CVE-2026-45247 to the KEV catalog comes days after Sansec said the PHP object injection vulnerability could...
Microsoft 365 Android Apps Let Any App Steal Account Tokens via Leftover Debug Flag

Microsoft 365 Android Apps Let Any App Steal Account Tokens via Leftover Debug Flag

Jun 03, 2026 Vulnerability / Mobile Security
A development flag left switched on in production builds of several Microsoft 365 Android apps disabled the check that limits account-token sharing to trusted Microsoft apps. Any other app on the same phone could ask for the signed-in user's token and get it, then read email, open files, browse the calendar, and send messages as that user. No password, no login screen, no permission prompt. Microsoft has patched it, and if you run Microsoft 365 apps on Android, update them. The bug, which Enclave calls FlagLeft , hit Word, PowerPoint, Excel, Microsoft 365 Copilot, Microsoft Loop, and OneNote, six apps with billions of downloads between them. Teams shipped with the same flag set to false and were not affected, which Enclave reads as a slip rather than a design. Microsoft 365 apps share account access on purpose, so signing into Word means you do not sign in again for PowerPoint. The handoff is supposed to verify who is asking and turn away anything that is not a trusted Mi...
Unpatched Windows Search URI Vulnerability Lets Attackers Steal NTLMv2 Hashes

Unpatched Windows Search URI Vulnerability Lets Attackers Steal NTLMv2 Hashes

Jun 03, 2026 Vulnerability / Network Security
Cybersecurity researchers have disclosed details of an unpatched issue that could be exploited to disclose a user's NTLMv2 hash to the attacker. Like in the case of CVE-2026-33829 , which impacted the Windows Snipping Tool's ms-screensketch: URI handler, the newly flagged issue resides in the search: URI handler, per Huntress . CVE-2026-33829 refers to a spoofing vulnerability that could expose sensitive information to an unauthorized actor. It was patched by Microsoft in April 2026. "An attacker could induce the user into clicking a specially crafted link in a Web browser or other URL source, by embedding it in a Web page or email message," Microsoft noted in its advisory at the time. "If the user approves the launching of the link, the crafted URL can induce the computer to connect to an SMB server of the attacker's choosing, which would disclose the user's NTLMv2 hash to the attacker, who could use this to authenticate as the user." Spe...

New HTTP/2 Bomb Vulnerability Allows Remote DoS on NGINX, Apache, IIS, Envoy & Cloudflare

Jun 03, 2026 Vulnerability / Server Security
Cybersecurity researchers have discovered a remote denial-of-service exploit that affects major web servers, including NGINX, Apache HTTPD, Microsoft IIS, Envoy, and Cloudflare Pingora. The vulnerability has been codenamed HTTP/2 Bomb by Calif. "The vulnerable behavior exists in each server's default HTTP/2 configuration," the company said, adding it was discovered by OpenAI Codex by chaining together two known techniques: a compression bomb and a Slowloris -style hold. "The bomb targets HPACK, HTTP/2's header compression scheme: one byte on the wire becomes one full header allocation on the server, repeated thousands of times per request," Calif added. "The hold is a zero-byte flow-control window that keeps the server from ever freeing any of it." HPACK is a dedicated header compression algorithm for HTTP/2 used for compressing request and response metadata using Huffman encoding that results in an average reduction of 30% in header siz...

Attackers Use LLM Agent for Post-Exploitation After Marimo CVE-2026-39987 Exploit

May 29, 2026 Vulnerability / Artificial Intelligence
An unknown threat actor has been observed using a large language model (LLM) agent to conduct post-compromise actions after obtaining initial access following the exploitation of a publicly-accessible Marimo network using a recently disclosed vulnerability. "The attacker compromised an internet-reachable Marimo notebook via CVE-2026-39987, extracted two cloud credentials from the compromised host, replayed them through a fanned-out egress pool to retrieve an SSH private key from AWS Secrets Manager, and used that key to drive eight short SSH sessions against a downstream SSH bastion server," Sysdig said . "The bastion phase exfiltrated the schema and full contents of an internal PostgreSQL database in under two minutes."

Critical Gogs RCE Vulnerability Lets Any Authenticated User Execute Arbitrary Code

Critical Gogs RCE Vulnerability Lets Any Authenticated User Execute Arbitrary Code

May 28, 2026 Vulnerability / Open Source
A critical security vulnerability has been disclosed in Gogs, a popular open-source self-hosted Git service, that allows an authenticated user to execute arbitrary code under certain conditions. The security flaw, per Rapid7, is rated 9.4 on the CVSS scoring system. It does not have a CVE identifier. "The vulnerability allows any authenticated user to achieve remote code execution (RCE) on the server by creating a pull request with a malicious branch name that injects the --exec flag into git rebase during the 'Rebase before merging' merge operation," security researcher Jonah Burgess said . Rebasing is a Git action that's used to take a sequence of commits from one feature branch and replay them on top of another base branch to create a linear project history. While "git rebase" solves the same problem as "git merge" -- i.e., integrating changes from one branch into another -- the former rewrites the project history by creating new c...
