CVE-2026-85588 Details
Description
phpMyFAQ versions before 4.1.8 include live TOTP shared secrets in plaintext within user data export ZIP files. Attackers obtaining exported archives can extract the TOTP seed and generate valid one-time codes to bypass two-factor authentication.
A vulnerability exists in phpMyFAQ versions prior to 4.1.8, where live TOTP shared secrets are included in plaintext within user data export ZIP files. This issue allows attackers who obtain these exported archives to extract the TOTP seed and generate valid one-time codes, effectively bypassing two-factor authentication. The vulnerability arises because the export function includes the raw TOTP seed from user data without any redaction, contrary to the proper exclusion of password hashes.
The recommended remediation is to remove the TOTP secret from the export data and establish a clear allowlist of non-credential fields that can be exported. Additionally, audit user data columns for sensitive information that should not be included in exports.
