Prior to 8.6.4, MapServer's PostGIS runtime filter translation in src/mappostgis.cpp and msPostGISLayerTranslateFilter() treats a filteritem as numeric when CONNECTIONTYPE POSTGIS and metadata such as gml_<item>_type=Integer are configured, but it does not verify that attacker-controlled CGI qstring or OGC API Features featureId input is a numeric literal. The unquoted input is concatenated into the generated PostgreSQL/PostGIS predicate, allowing an unauthenticated remote attacker with access to an affected query endpoint to bypass predicates, enumerate unintended records, perform boolean-based or time-based SQL injection, and increase database load. The issue does not by itself establish database modification capabilities. This issue is fixed in version 8.6.4.","published":"2026-09-17T21:17:15.260","modified":"2026-09-17T21:17:15.260","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/MapServer/MapServer/commit/65f1b53c258df2abdf6ce1f437c29e75e9976247","label":"MapServer/MapServer@65f1b53"},"references":[{"type":"WEB","url":"https://github.com/MapServer/MapServer/commit/65f1b53c258df2abdf6ce1f437c29e75e9976247"},{"type":"WEB","url":"https://github.com/MapServer/MapServer/commit/bd59d49779d2ecc64ca8dc1281c53231a50b698e"},{"type":"WEB","url":"https://github.com/MapServer/MapServer/pull/7516"},{"type":"WEB","url":"https://github.com/MapServer/MapServer/releases/tag/rel-8-6-4"},{"type":"WEB","url":"https://github.com/MapServer/MapServer/security/advisories/GHSA-xp29-8wp5-wc3p"},{"type":"WEB","url":"https://mapserver.org/development/changelog/changelog-8-6.html#changelog-8-6"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-17T21:17:15.260"}}
