{"id":"BIT-keydb-2025-62507","summary":"Redis: Bug in XACKDEL may lead to stack overflow and potential RCE","details":"Redis is an open source, in-memory database that persists on disk. In versions 8.2.0 and above, a user can run the XACKDEL command with multiple ID's and trigger a stack buffer overflow, which may potentially lead to remote code execution. This issue is fixed in version 8.2.3. To workaround this issue without patching the redis-server executable is to prevent users from executing XACKDEL operation. This can be done using ACL to restrict XACKDEL command.","aliases":["BIT-redis-2025-62507","CVE-2025-62507","GHSA-jhjx-x4cf-4vm8"],"modified":"2026-09-08T08:48:07.615348188Z","published":"2025-11-07T08:40:53.783Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:redis:redis:*:*:*:*:*:*:*:*"]},"references":[{"type":"FIX","url":"https://github.com/redis/redis/commit/5f83972188f6e5b1d6f1940218c650a9cbdf7741"},{"type":"ARTICLE","url":"https://github.com/redis/redis/releases/tag/8.2.3"},{"type":"ADVISORY","url":"https://github.com/redis/redis/security/advisories/GHSA-jhjx-x4cf-4vm8"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-62507"}],"affected":[{"package":{"name":"keydb","ecosystem":"Bitnami","purl":"pkg:bitnami/keydb"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.2.0"},{"fixed":"8.2.3"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/keydb/BIT-keydb-2025-62507.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
