8.7 highEPSS 0.2%

High (8.7) in openclaw openclaw. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in openclaw 2026.2.15.

OpenClaw versions prior to 2026.2.15 use SHA-1 to hash sandbox identifier cache keys for Docker and browser sandbox configurations, which is deprecated and vulnerable to collision attacks. An attacker can exploit SHA-1 collisions to cause cache poisoning, allowing one sandbox configuration to be misinterpreted as another and enabling unsafe sandbox state reuse.
