## Summary Tlon media downloads can bypass core safety limits and exhaust disk ## Current Maintainer Triage - Status: narrow - Normalized severity: low - Assessment: Shipped v2026.3.28 Tlon media downloads bypassed core size/count/cleanup limits, but this is availability-only resource exhaustion in a bundled plugin path, so low. ## 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) - `2194587d70d2aef863508b945319c5a7c88b12ce` — 2026-03-31T19:40:15+09:00 ## Release Process Note - The fix is already present in released version `2026.3.31`. - This draft looks ready for final maintainer disposition or publication, not additional code-fix work. Thanks @AntAISecurityLab for reporting.
