## Summary LINE webhook handler lacks shared pre-auth concurrency budget before signature verification ## Current Maintainer Triage - Status: open - Normalized severity: low - Assessment: Shipped v2026.3.28 lacks a shared pre-auth concurrency budget on the public LINE webhook path, but the effect is bounded transient availability loss only, so low fits. ## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version: `2026.3.31` - Vulnerable version range: `<=2026.3.28` - Patched versions: `>= 2026.3.31` - First stable tag containing the fix: `v2026.3.31` ## Fix Commit(s) - `57c47d8c7fbf5a2e70cc4dec2380977968903cad` — 2026-03-31T19:34:25+09:00 OpenClaw thanks @nexrin for reporting.
