{"schema":"threatline.record/2","record":{"id":"CVE-2026-107816","aliases":["GHSA-wfqg-88r5-55f6"],"summary":"MariaDB: `qc_info` plugin can do OOB reads if query contains \\0","details":"MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the qc_info plugin could be confused by a query containing embedded null bytes. Reading information_schema.query_cache_info after such a query was cached could access data beyond the end of a heap-allocated buffer, potentially disclosing adjacent memory or crashing the server. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.","categories":["Databases"],"product":"server","vendor":"MariaDB","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107816","source_modified_at":"2026-10-13T20:27:21.152Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"server","vendor":"MariaDB","versions":[{"version":">= 10.6.1, < 10.6.28","status":"affected"},{"version":">= 10.11.1, < 10.11.19","status":"affected"},{"version":">= 11.4.1, < 11.4.13","status":"affected"},{"version":">= 11.8.1, < 11.8.9","status":"affected"},{"version":">= 12.3.1, < 12.3.3","status":"affected"},{"version":">= 13.0.1, < 13.0.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00312,"percentile":0.22834,"score_date":"2026-10-23"},"published_at":"2026-10-09T17:19:00.365Z","modified_at":"2026-10-13T20:27:21.152Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107816","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T20:27:21.152Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107816","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/MariaDB/server/security/advisories/GHSA-wfqg-88r5-55f6","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/MariaDB/server/commit/0931994096b84ecc9ffc8eb3517c7e09e6e8631e","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://jira.mariadb.org/browse/MDEV-40670","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-13T20:13:34.743204Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-13T20:27:21.152Z","content_hash":"ec91ce483c12260b20e45e3c60d609cc502a9b690c2c4515b33ff079d48ba08f"}}
