From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, ST_AsText can write beyond an allocated output buffer when converting deeply nested GeometryCollections because recursive WKT serialization does not account for bytes consumed or reserve sufficient space. A low-privileged remote attacker can submit a specially crafted GIS object to corrupt memory and potentially achieve code execution when combined with another vulnerability. 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.","evidence":"cve:CVE-2026-85746","products":[{"name":{"value":"server","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"critical","structured":{"id":"CVE-2026-85746","aliases":["CVE-2026-85746"],"metrics":[{"cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":9.9,"attackVector":"NETWORK","baseSeverity":"CRITICAL","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"MariaDB","product":"server","versions":[{"status":"affected","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"}]}],"modified":"2026-10-16T17:05:31.146Z","provider":"cve","references":["https://github.com/MariaDB/server/security/advisories/GHSA-8fvj-c57c-pggx","https://github.com/MariaDB/server/commit/5c04ca5524385356ff7cf84974a7d491974c1f85","https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","https://jira.mariadb.org/browse/MDEV-40329"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-85746","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-10-16T16:49:55.618818Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-16T17:05:31.146Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-10-16T16:27:36.763Z"}}},"related_cves":[{"value":"CVE-2026-85746","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"},"priority":{"reasons":["publisher_severity"],"severity":"critical","linked_cves":[],"fix_available":false,"known_exploited":false,"publisher_severity":"critical"},"context_update":false}],"next_after":32838,"next_before":32838}
