AI-Generated

PostgreSQL versions prior to 18.5, 17.11, 16.15, 15.19, and 14.24 are vulnerable due to an integer wraparound in the tsvector and tsquery functions, allowing unprivileged database users to exploit out-of-bounds memory writes. This vulnerability could lead to arbitrary code execution with the privileges of the database server user, posing a significant risk to database integrity and security. Database administrators and organizations using affected PostgreSQL versions should prioritize patching to mitigate potential exploitation.

Original NVD Description

Integer wraparound in PostgreSQL tsvector and tsquery data type functions allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds, via crafted large inputs. This may execute arbitrary code as the operating system user running the database. These types are typically sourced from application logic, not taken from the application's user. Hence, application users attacking the database, through the application as a conduit, are unlikely. CVE-2026-6473 had fixed similar problems. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
