The FlatGeobuf property metadata decoder verifies that a string length field is present but fails to verify that the subsequent string body is contained within the supplied buffer before materializing it into a SQL-visible value, enabling memory disclosure or denial of service.","published":"2026-08-13T16:19:05.333","modified":"2026-08-13T16:19:05.333","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://gitea.osgeo.org/postgis/postgis/raw/tag/3.7.0beta2/NEWS"},{"type":"WEB","url":"https://mehmetince.net/part-1-6-systemic-risks-in-the-managed-postgresql-industry-extension-risks-are-real-exploiting-postgis-memory-corruption-bug-at-neondb-supabase-and-many-more/"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/postgis-0beta2-out-of-bounds-read-via-flatgeobuf-buffer"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T16:19:05.333"}}
