The vendor was contacted early about this disclosure but did not respond in any way.
A denial-of-service vulnerability has been identified in phpMyAdmin SQL-Parser versions 6.0.0 and 6.0.1. The issue arises in the ExplainStatement parsing function, where an argument manipulation leads to incorrect type conversion. This flaw allows remote exploitation, causing an uncaught TypeError that terminates the process. The vulnerability has been publicly disclosed, and the author reported it to the vendor, who did not respond.
To address this vulnerability, the token type should be validated before assignment to ensure it is an integer. After applying this fix, the parser can handle the input without crashing and log an appropriate error.
