{"id":"BIT-valkey-2026-25243","summary":"redis-server RESTORE invalid memory access may allow remote code execution","details":"Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE 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 is patched in version 8.6.3.","aliases":["BIT-keydb-2026-25243","BIT-redis-2026-25243","CVE-2026-25243"],"modified":"2026-05-07T12:26:25.304685978Z","published":"2026-05-07T11:52:00.374Z","database_specific":{"cpes":["cpe:2.3:a:valkey-io:valkey:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://github.com/redis/redis/releases/tag/8.6.3"},{"type":"WEB","url":"https://github.com/redis/redis/security/advisories/GHSA-c8h9-259x-jff4"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25243"}],"affected":[{"package":{"name":"valkey","ecosystem":"Bitnami","purl":"pkg:bitnami/valkey"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"7.2.13"},{"introduced":"8.0.0"},{"fixed":"8.0.8"},{"introduced":"8.1.0"},{"fixed":"8.1.7"},{"introduced":"9.0.0"},{"fixed":"9.0.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/valkey/BIT-valkey-2026-25243.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/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":"1.7.5"}
