Attackers can craft malicious rule rows with out-of-range Weight values to trigger out-of-bounds reads in the load_value array, causing the PostgreSQL backend process to crash and terminate all cluster sessions.","published":"2026-09-13T12:17:16.400","modified":"2026-09-13T12:17:16.400","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/postgis/address_standardizer/commit/a5cb4b1360a040973092f13b1af97a718e7e104a","label":"postgis/address_standardizer@a5cb4b1"},"references":[{"type":"WEB","url":"https://github.com/postgis/address_standardizer"},{"type":"WEB","url":"https://github.com/postgis/address_standardizer/blob/e987949e0fccff6a0e7a6d3f86814d5c7a01f481/NEWS.md"},{"type":"WEB","url":"https://github.com/postgis/address_standardizer/blob/v3.7.0/src/analyze.c#L860"},{"type":"WEB","url":"https://github.com/postgis/address_standardizer/blob/v3.7.0/src/gamma.c#L301-L311"},{"type":"WEB","url":"https://github.com/postgis/address_standardizer/commit/a5cb4b1360a040973092f13b1af97a718e7e104a"},{"type":"WEB","url":"https://github.com/postgis/address_standardizer/commit/e987949e0fccff6a0e7a6d3f86814d5c7a01f481"},{"type":"WEB","url":"https://github.com/postgis/address_standardizer/pull/6"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/postgis-address-standardizer-through-3.7.0-out-of-bounds-read-via-unvalidated-rule-weight"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-13T12:17:16.400"}}
