{"id":"BIT-keydb-2026-23631","summary":"redis-server Lua use-after-free may allow remote code execution","details":"Redis is an in-memory data structure store. In all versions of redis-server with Lua scripting, an authenticated attacker can exploit the master-replica synchronization mechanism to trigger a use-after-free on replicas where replica-read-only is disabled or can be disabled, which may lead to remote code execution. A workaround is to prevent users from executing Lua scripts or avoid using replicas where replica-read-only is disabled. This is patched in version 8.6.3.","aliases":["BIT-redis-2026-23631","BIT-valkey-2026-23631","CVE-2026-23631","GHSA-8ghh-qpmp-7826"],"modified":"2026-09-10T16:01:41.493987030Z","published":"2026-05-07T08:42:54.096Z","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-8ghh-qpmp-7826"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23631"},{"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-2026:26306"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:26540"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:33444"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-23631"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2466788"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-23631.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":"7.2.0"},{"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-2026-23631.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.9.0"}
