{"id":"CVE-2026-73514","summary":"PostGIS address_standardizer Out-of-Bounds Write via standardize_address()","details":"The address_standardizer extension for PostGIS through 3.7.0, fixed in commit 423570b, contains an out-of-bounds write vulnerability that allows a database user with the ability to supply caller-controlled relation names to standardize_address() to trigger memory corruption by providing a rules table with a classification Type value exceeding the fixed class range. 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.","modified":"2026-08-15T16:52:31.940543Z","published":"2026-08-13T15:36:14.564Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-787"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73514.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"423570b0dbf6cd9f6fc36de28a636e7b6e9aa8aa"}]}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73514.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73514"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/postgis-address-standardizer-out-of-bounds-write-via-standardize-address"},{"type":"REPORT","url":"https://github.com/postgis/address_standardizer/pull/3"},{"type":"FIX","url":"https://github.com/postgis/address_standardizer/commit/423570b0dbf6cd9f6fc36de28a636e7b6e9aa8aa"},{"type":"FIX","url":"https://github.com/postgis/address_standardizer/pull/4"},{"type":"PACKAGE","url":"https://github.com/postgis/address_standardizer"},{"type":"EVIDENCE","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/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/postgis/address_standardizer","events":[{"introduced":"0"},{"fixed":"fa11ff53eb49b863d9ffff37f6afd5ff9299c581"},{"fixed":"423570b0dbf6cd9f6fc36de28a636e7b6e9aa8aa"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.7.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v3.7.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73514.json","vanir_signatures_modified":"2026-08-15T16:52:31Z","vanir_signatures":[{"target":{"file":"src/address_standardizer.c","function":"debug_standardize_address"},"deprecated":false,"digest":{"function_hash":"310506951008264446587210304497951151757","length":3616},"id":"CVE-2026-73514-19b9a13d","signature_type":"Function","signature_version":"v1","source":"https://github.com/postgis/address_standardizer/commit/fa11ff53eb49b863d9ffff37f6afd5ff9299c581"},{"source":"https://github.com/postgis/address_standardizer/commit/fa11ff53eb49b863d9ffff37f6afd5ff9299c581","target":{"file":"src/address_standardizer.c"},"deprecated":false,"digest":{"line_hashes":["14064042082914719957995780970075966614","236945478507379489297572981162242406697","66439846191087393758917437313737124263"],"threshold":0.9},"id":"CVE-2026-73514-7ff76562","signature_type":"Line","signature_version":"v1"}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
