What is CVE-2026-73514?
CVE-2026-73514 is a high-severity memory corruption vulnerability in PostGIS address_standardizer, published on 13 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-787
