CVE-2026-73514

CVE-2026-73514 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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.. EPSS estimates a 0.82% chance of exploitation in the next 30 days.
