CVE-2026-18470Public exploitNetwork attack vector

Unauthenticated email disclosure via recoverable response masking

Published Aug 10, 2026 · Updated Aug 10, 2026

Information disclosure in XootiX Login & Register Forms before 4.0.2 allows remote attackers to obtain registered users' email addresses. The lost-password AJAX handler accepts an account identifier without proving ownership and returns masking that preserves each address segment's length and structure; a complete candidate can also be confirmed. Exposure requires the non-default Send Verification Code mode, and the response can reveal administrator addresses without changing accounts or interrupting service.
