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.","publishedAt":"2025-11-04T21:24:44.802Z","updatedAt":"2026-02-26T17:47:18.954Z","severity":{"score":7.7,"label":"High","version":"4.0","vector":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["redis redis"],"affected":[{"vendor":"redis","product":"redis","versions":[{"version":">= 8.2.0, < 8.2.3","status":"affected"}]}],"references":["https://github.com/redis/redis/security/advisories/GHSA-jhjx-x4cf-4vm8","https://github.com/redis/redis/commit/5f83972188f6e5b1d6f1940218c650a9cbdf7741","https://github.com/redis/redis/releases/tag/8.2.3"],"weaknesses":["CWE-20","CWE-121"],"ingestedAt":"2026-10-29T20:09:48.677Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/62xxx/CVE-2025-62507.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-62507","state":"PUBLISHED","datePublished":"2025-11-04T21:24:44.802Z","dateUpdated":"2026-02-26T17:47:18.954Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-10-15T15:03:28.133Z"},"containers":{"cna":{"title":"Redis: Bug in XACKDEL may lead to stack overflow and potential RCE","descriptions":[{"lang":"en","value":"Redis is an open source, in-memory database that persists on disk.
