Malicious Twitch Browser Extension Leaks OAuth Tokens From Nearly 31,000 Users

Malicious Twitch extension 'Twitch Enhanced Viewer | JeetBot' leaked OAuth tokens from nearly 31,000 users to Russian bot-service proxy servers.

Socket researchers found the 'Twitch Enhanced Viewer | JeetBot' browser extension forwarded users' live Twitch OAuth tokens as an &auth= query parameter to operator-controlled proxy servers, affecting about 30,000 Chrome users and 604 Firefox users. The tokens, written in cleartext to proxy logs, are bearer credentials granting access to chat, whispers, and account settings without password or 2FA. The operator is a Russian commercial Twitch/Kick/VK-Live bot SaaS linked to Cyprus-based developer Aleksandr Popov; earlier v4.x builds also POSTed tokens to a set-token endpoint. Firefox add-on version 85.8.7 stops the token forwarding, but previously transmitted tokens remain valid until revoked.

Twitch extension with 30K installs exposes users’ OAuth tokens

Twitch extension with 30,000+ installs exfiltrates users' OAuth session tokens to Russian-run JeetBot proxy servers.

Socket analysis shows the "Twitch Enhanced Viewer | JeetBot" browser extension, with over 30,000 installs on the official Chrome and Firefox stores, captures the Twitch web client's authorization header and extracts the user's OAuth token. The token is appended as an auth= URL parameter to video playlist requests routed through JeetBot proxy servers, landing in cleartext request logs retrievable by the Russian-language bot service vendor; ten hardcoded Russian-language channels are exempted. Earlier versions used more explicit token exfiltration, and the extension remained live in both stores at publication. Socket recommends removing the extension, disconnecting all Twitch sessions, and re-authenticating.

Malicious Twitch Extension Exposes 31,000 Users' OAuth Tokens

Malicious Twitch extension 'Twitch Enhanced Viewer | JeetBot' forwarded live OAuth session tokens of roughly 31,000 users to Russian JeetBot proxy servers.

Socket research found the cross-store extension Twitch Enhanced Viewer | JeetBot (about 30,000 Chrome users and 552 Firefox users) routing Twitch video requests through JeetBot proxy servers with the account-scoped OAuth bearer token appended in cleartext as a URL query parameter. Version 4.x builds, including 4.8 from January 2026, posted captured tokens to dedicated set-token endpoints on JeetBot infrastructure with backups on two Deno services. Token holders can read and send whispers, post in chat, and spend channel points without a password or 2FA; listings were still live at publication and users are advised to remove the extension and re-authenticate.

Cisco Secure Firewall Threat Defense Software TLS 1.3 Denial of Service Vulnerability

A TLS 1.3 buffer management flaw in Cisco Secure Firewall Threat Defense lets remote attackers crash the LINA process and reload devices.

A vulnerability in the TLS 1.3 implementation of Cisco Secure Firewall Threat Defense (FTD) software allows an unauthenticated remote attacker to cause a denial of service via crafted TLS 1.3 packets sent to a TLS 1.3-enabled listening socket. Improper buffer management causes the LINA process to crash, forcing a device reload that can occur before or after connection authentication. Cisco has released software updates to address the flaw.

Homebrew 7.0.0 is out, here’s what changed for security

Homebrew 7.0.0 closes eight security advisories, including a High sudo execution bug fixed in 6.0.12, and ships brew vulns vulnerability scanning.

Homebrew 7.0.0 closes eight security advisories rated one High, two Moderate, and five Low. The High flaw let unsigned cask removal metadata execute commands with sudo (fixed in 6.0.12), while the 7.0.0 Moderate closes a LaunchServices escape that let a malicious cask execute code outside the macOS install sandbox. The release ships brew vulns, which checks installed formulae against OSV.dev, extends build attestation verification to third-party tap bottles, and replaces Bubblewrap with Landlock sandboxing on Linux.

Parallels Desktop Flaw Lets Non-Admin Mac Users Gain Root, but Intel Macs Can't Install Fix

JFrog disclosed CVE-2026-90894, a 7.8-rated local privilege escalation in Parallels Desktop for Mac, patched only in version 27, which Intel Macs cannot install.

JFrog researcher Yuval Moravchick disclosed CVE-2026-90894 (dubbed ParaShells, CVSS 7.8), a local privilege escalation in Parallels Desktop for Mac that lets non-admin users run code as root. The root-level prl_disp_service listens on a world-writable socket, and argument injection into a tar command via QProcess::splitCommand and the --use-compress-program option yields code execution as root, demonstrated on Parallels Desktop 26.4.0 build 57513 on Apple silicon. The fix appears in version 27.0.0, but Parallels Desktop 27 requires Apple silicon, leaving Intel Macs on the 26.x line with no build JFrog describes as fixed. No exploitation in the wild has been reported and Parallels has not published a statement.
