Description

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: `= 2026.3.31` • 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.
