RedisBloom RESTORE invalid memory access may allow remote code execution (CVE-2026-25589)
RedisBloom versions prior to 2.8.20 contain a vulnerability in the RESTORE command handling that allows an authenticated attacker with RESTORE permission to supply crafted serialized payloads. This can cause invalid memory access and potentially lead to remote code execution. The issue is fixed in RedisBloom version 2.8.20. A workaround is to restrict RESTORE command access using ACL rules.
AI Analysis
Technical Summary
RedisBloom, a Redis module for probabilistic data structures, improperly validates serialized values processed via the Redis RESTORE command in all versions before 2.8.20. An authenticated attacker with permission to execute RESTORE can provide a crafted serialized payload that triggers invalid memory access, potentially resulting in remote code execution. The vulnerability affects Redis versions >=8.0.0 <8.2.6, >=8.3.0 <8.4.3, and >=8.5.0 <8.6.3 when RedisBloom is loaded. The issue is resolved in RedisBloom 2.8.20.
Potential Impact
An attacker with authentication and RESTORE command permission on a Redis server running a vulnerable RedisBloom module can cause invalid memory access and potentially execute arbitrary code remotely. This elevates the risk of full system compromise or service disruption if exploited.
Mitigation Recommendations
Upgrade RedisBloom to version 2.8.20 or later, where this vulnerability is fixed. Alternatively, restrict access to the RESTORE command using Redis ACL rules to prevent unauthorized use. No other mitigation is indicated by the vendor advisory.
