CVE-2026-28479

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.

Summary		(es) Versiones de OpenClaw anteriores a 2026.2.15 utilizan SHA-1 para aplicar hash a las claves de caché de identificadores de sandbox para configuraciones de sandbox de Docker y de navegador, lo cual está obsoleto y es vulnerable a ataques de colisión. Un atacante puede explotar las colisiones de SHA-1 para causar envenenamiento de caché, permitiendo que una configuración de sandbox sea malinterpretada como otra y habilitando la reutilización insegura del estado del sandbox.
