CVE-2026-128027

FrankenPHP before 1.1.11 Delayed Propagation of Base Image Security Fixes

  • Critical 9.8

Description

FrankenPHP Docker images before 1.1.11 were rebuilt only when new base image tags were created, so security fixes that Alpine, PHP, and Go applied under existing tags were not propagated. Remote attackers could exploit known flaws in the stale system libraries, such as CVE-2025-15467 in libcrypto3, to execute code.
