{"id":"BIT-keydb-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-redis-2026-25243","BIT-valkey-2026-25243","CVE-2026-25243","GHSA-c8h9-259x-jff4"],"modified":"2026-09-08T08:48:07.515428194Z","published":"2026-05-07T11:43:05.710Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:redis:redis:*:*:*:*:*:*:*:*"]},"references":[{"type":"ARTICLE","url":"https://github.com/redis/redis/releases/tag/8.6.3"},{"type":"ADVISORY","url":"https://github.com/redis/redis/security/advisories/GHSA-c8h9-259x-jff4"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25243"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:23229"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:25216"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:25219"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:25925"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:26008"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:26233"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:26306"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:26540"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:27716"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:27787"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:28139"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:28142"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:29817"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:33427"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-25243"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2466828"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-25243.json"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:14316"}],"affected":[{"package":{"name":"keydb","ecosystem":"Bitnami","purl":"pkg:bitnami/keydb"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"6.2.22"},{"introduced":"7.0.0"},{"fixed":"7.2.14"},{"introduced":"7.3.0"},{"fixed":"7.4.9"},{"introduced":"8.0.0"},{"fixed":"8.2.6"},{"introduced":"8.3.0"},{"fixed":"8.4.3"},{"introduced":"8.5.0"},{"fixed":"8.6.3"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/keydb/BIT-keydb-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":"1.9.0"}
