Redis Patch Bypass Enables Multiple RCE Exploits as PoCs for TLS and Stream Vulnerabilities Go Public
Multiple remote code execution vulnerabilities have been disclosed in Redis over the past month, including a critical patch bypass for CVE-2026-25243 that reintroduces Double Free flaws via crafted stream operations. The latest issue, QVD-2026-58458 affecting the TLS pending list, now has full technical details and a working PoC available, following the earlier QVD-2026-55651 disclosure. All three flaws impact nearly every production version still in use, from Redis 6.2.22 and below through 7.4.9 and 8.6.4. Although authentication is required, widespread weak or empty password configurations and exposed instances make exploitation trivial for attackers. Successful compromise grants arbitrary code execution in the Redis process context, enabling standard post-exploitation steps such as credential harvesting and lateral movement across internal networks. Organizations are urged to inventory all instances, apply the latest patches immediately, restrict network access via ACLs, and monitor for anomalous use of commands like XGROUP, EVAL, and RESTORE.
