CVE-2026-11571: CWE-200 Information Exposure in Everest Forms
The Everest Forms WordPress plugin before 3.5.0 does not reliably delete temporary CSV files generated during email-notification processing and leaves them publicly accessible in the uploads directory, allowing unauthenticated attackers to retrieve other users' form submission records via predictable, enumerable filenames.
AI Analysis
Technical Summary
CVE-2026-11571 is an information exposure vulnerability (CWE-200) in the Everest Forms WordPress plugin versions prior to 3.5.0. The plugin fails to reliably delete temporary CSV files generated during email-notification processing, leaving them accessible in the uploads directory. Because the filenames are predictable and enumerable, unauthenticated attackers can retrieve sensitive form submission records belonging to other users.
Potential Impact
The vulnerability allows an unauthenticated attacker to access sensitive user-submitted form data by downloading temporary CSV files that should have been deleted. This results in a confidentiality breach with high impact, as sensitive information can be exposed without authentication or user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting access to the uploads directory or disabling email-notification processing that generates these temporary CSV files to prevent unauthorized access.
