Summary
FrankenPHP 1.8.0 before 1.13.2 Out-of-Bounds Write via Bundled Brotli Decoder
Details

FrankenPHP standalone static binaries 1.8.0 before 1.13.2 bundle the PHP brotli extension statically linked with Brotli 1.2.0, whose decoder contains an out-of-bounds write (CVE-2026-111497). Unauthenticated remote attackers can send crafted data to applications that pass it to brotli_uncompress_add() to crash the entire FrankenPHP process, and possibly cause memory disclosure or code execution.
