Critical 10.0 RCE Flaw in Redis Exposes 60,000 Instances

⚠ The popular Redis in-memory data store received an urgent patch for a critical use-after-free vulnerability tracked as CVE-2025-49844 (RediShell), which can escape the Lua script sandbox and achieve remote code execution on the host. Exploitation requires authentication, but many deployments disable it; researchers estimate roughly 60,000 internet-exposed instances lack authentication. Redis released fixes on Oct. 3 across multiple branches and administrators are urged to patch exposed servers immediately and enable hardening controls.

Critical Redis Flaw 'RediShell' Exposes 60,000 Servers

🚨 Redis has a critical, decade‑old vulnerability identified as CVE-2025-49844 (RediShell) in its embedded Lua scripting engine that can let authenticated users escape the sandbox and execute arbitrary code on the host. Researchers at Wiz report roughly 330,000 Redis instances are exposed online, with about 60,000 lacking authentication. Redis and Wiz disclosed the issue on October 3 and published patches; administrators should apply updates, restrict access, and disable Lua scripting if not required.

Redis 13-Year Use-After-Free Flaw Rated CVSS 10.0 Severity

⚠️ Redis disclosed a maximum-severity vulnerability, CVE-2025-49844 (RediShell), a use-after-free bug in its Lua scripting implementation that has been assigned a CVSS score of 10.0. An authenticated user can submit crafted Lua scripts to manipulate the garbage collector, trigger a use-after-free, and potentially achieve remote code execution on the host. The issue affects all Redis versions with Lua and was fixed in 6.2.20, 7.2.11, 7.4.6, 8.0.4, and 8.2.2 (released Oct 3, 2025). Administrators should immediately restrict EVAL/EVALSHA via ACLs, avoid exposing Redis instances to the internet, enforce strong authentication, and apply the patches without delay.

Redis warns of critical Lua RCE flaw in many instances

🔒 The Redis security team has released patches for CVE-2025-49844, a maximum-severity use-after-free in the bundled Lua interpreter that can enable remote code execution when an attacker supplies a specially crafted Lua script. Wiz researchers, who disclosed the issue at Pwn2Own Berlin and dubbed it RediShell, found approximately 330,000 Redis instances exposed online and at least 60,000 requiring no authentication. Administrators should apply the published fixes (for example, 7.22.2-12 and later; OSS/CE/Stack variants also updated) immediately and implement mitigations such as enabling authentication, disabling Lua scripting where possible, running Redis as a non-root user, and restricting network access.

GeoServer Exploits, PolarEdge, Gayfemboy Expand Cybercrime

🛡️ Cybersecurity teams report coordinated campaigns exploiting exposed infrastructure and known flaws to monetize or weaponize compromised devices. Attackers have abused CVE-2024-36401 in GeoServer to drop lightweight Dart binaries that monetize bandwidth via legitimate passive-income services, while the PolarEdge botnet and Mirai-derived gayfemboy expand relay and DDoS capabilities across consumer and enterprise devices. Separately, TA-NATALSTATUS targets unauthenticated Redis instances to install stealthy cryptominers and persistence tooling.
