CVE-2026-28479: Openclaw

Critical severity, CVSS 9.1. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
