CVE-2026-25589
RedisBloom RESTORE invalid memory access may allow remote code execution
Description
RedisBloom is a probabilistic data structures module for Redis. In all versions of RedisBloom before 2.8.20, the module does not properly validate serialized values processed through the Redis RESTORE command. An authenticated attacker with permission to execute RESTORE on a server with the RedisBloom module loaded can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This issue is fixed in version 2.8.20.

Action Type Old Value New Value Added Translation Title: RedisBloom, Description: RedisBloom es un módulo de estructuras de datos probabilísticas para Redis. En todas las versiones de RedisBloom anteriores a la 2.8.20, el módulo no valida correctamente los valores serializados procesados a través del comando RESTORE de Redis. Un atacante autenticado con permiso para ejecutar RESTORE en un servidor con el módulo RedisBloom cargado puede proporcionar una carga útil serializada manipulada que desencadena un acceso a memoria no válido y puede conducir a la ejecución remota de código. Una solución alternativa es restringir el acceso al comando RESTORE con reglas ACL. Este problema está solucionado en la versión 2.8.20. -
