CVE-2009-4136 is a privilege escalation vulnerability affecting multiple versions of PostgreSQL (7.4.x through 8.4.x). It allows remote authenticated users to gain elevated privileges by exploiting improper session-local state management during index function execution by a superuser, specifically through crafted index functions that modify search_path or prepared statements. With a CVSS score of 6.5 (medium), this vulnerability has a network attack vector, low attack complexity, and can lead to partial confidentiality, integrity, and availability impacts. There is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or KEV listing, though it has garnered some community discussion.
