CyberRota Analysis
AI-GeneratedA heap buffer overflow vulnerability in PostgreSQL's regexp functionality allows attackers to execute arbitrary code as the operating system user running the database, particularly through specially crafted text that bypasses encoding validation. This issue arises from unexpected data growth during processing, posing a significant risk to database integrity and security. Organizations using affected versions prior to 18.5, 17.11, 16.15, 15.19, and 14.24 should prioritize patching to mitigate potential exploitation.
Original NVD Description
Heap buffer overflow in PostgreSQL regexp allows the query author to execute arbitrary code as the operating system user running the database, via text that would not pass encoding validation. This shares heritage with CVE-2026-2006, but this case involved unanticipated data growth when round-tripped through pg_wchar. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
