CVE-2021-26939Public exploitNetwork attack vector

SQL dump disclosure via search-indexed content

Published Feb 10, 2021 · Updated Aug 3, 2024

Information disclosure in henriquedornas 5.2.17 allows remote attackers to read phpMyAdmin SQL dump contents through web search. The only public artifact supplies a Google advanced-search query that locates indexed phpMyAdmin dump markers and an administrator string; it identifies no flawed application code or request handler. MITRE marks the claim disputed because third parties describe the exposure as site-specific, so the record does not establish a generally affected software product.
