CVE-2006-4031

CVE-2006-4031 describes a privilege escalation vulnerability in MySQL versions 4.1.x prior to 4.1.21 and 5.0.x prior to 5.0.24. A local attacker could retain access to a table via a previously created MERGE table, even after their privileges for the original table were revoked, potentially bypassing security policies. With a CVSS score of 2.1 (low severity), this vulnerability requires local access and has a low attack complexity, primarily impacting confidentiality. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this decade-old flaw.
