Attackers can craft a malicious rules table entry with an oversized rule type value that is used without bounds checking as an index into an internal output-link table, resulting in an out-of-bounds write.","published":"2026-08-13T16:19:05.190","modified":"2026-08-13T16:19:05.190","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/postgis/address_standardizer/commit/423570b0dbf6cd9f6fc36de28a636e7b6e9aa8aa","label":"postgis/address_standardizer@423570b"},"references":[{"type":"WEB","url":"https://github.com/postgis/address_standardizer/commit/423570b0dbf6cd9f6fc36de28a636e7b6e9aa8aa"},{"type":"WEB","url":"https://github.com/postgis/address_standardizer/pull/3"},{"type":"WEB","url":"https://github.com/postgis/address_standardizer/pull/4"},{"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-address-standardizer-out-of-bounds-write-via-standardize-address"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T16:19:05.190"}}
