  • May 5, 2026RedisBloom is a probabilistic data structures module for Redis.CVE-2026-25589 · Other software · RedisBloom · reported by GitHubHigh 7.7

    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.

  • Jan 8, 2025RedisBloom adds a set of probabilistic data structures to Redis.CVE-2024-55656 · Other software · RedisBloom · reported by GitHubHigh 8.8

    RedisBloom adds a set of probabilistic data structures to Redis. There is an integer overflow vulnerability in RedisBloom, which is a module used in Redis. The integer overflow vulnerability allows an attacker (a redis client which knows the password) to allocate memory in the heap lesser than the required memory due to wraparound. Then read and write can be performed beyond this allocated memory, leading to info leak and OOB write. The integer overflow is in CMS.INITBYDIM command, which initialize a Count-Min Sketch to dimensions specified by user. It accepts two values (width and depth) and uses them to allocate memory in NewCMSketch(). This vulnerability is fixed in 2.2.19, 2.4.12, 2.6.14, and 2.8.2.

    RedisBloom adds a set of probabilistic data structures to Redis. Starting in version 2.0.0 and prior to version 2.4.7 and 2.6.10, authenticated users can use the `CF.RESERVE` command to trigger a runtime assertion and termination of the Redis server process. The problem is fixed in RedisBloom 2.4.7 and 2.6.10.

    RedisBloom adds a set of probabilistic data structures to Redis. Starting in version 2.0.0 and prior to version 2.4.7 and 2.6.10, specially crafted `CF.LOADCHUNK` commands may be used by authenticated users to perform heap overflow, which may lead to remote code execution. The problem is fixed in RedisBloom 2.4.7 and 2.6.10.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
