Hi, The following vulnerability was published for redis. CVE-2025-32023[0]: | Redis is an open source, in-memory database that persists on disk. | From 2.8 to before 8.0.3, 7.4.5, 7.2.10, and 6.2.19, an | authenticated user may use a specially crafted string to trigger a | stack/heap out of bounds write on hyperloglog operations, | potentially leading to remote code execution. The bug likely affects | all Redis versions with hyperloglog operations implemented. This | vulnerability is fixed in 8.0.3, 7.4.5, 7.2.10, and 6.2.19. An | additional workaround to mitigate the problem without patching the | redis-server executable is to prevent users from executing | hyperloglog operations. This can be done using ACL to restrict HLL | commands. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
