Protected-content disclosure via hard-coded encryption key
Published Jun 27, 2023 · Updated Apr 8, 2026
Sensitive information exposure in EmbedPress 3.7.3 and earlier allows remote attackers to read password-protected content. The lock_content_form_handler and display_password_form functions encrypt content-protection data with a hard-coded key, allowing captured ciphertext to be decrypted outside the site. No WordPress account is required, but a site must publish content protected by the affected EmbedPress password feature; the flaw exposes that content without granting write access.
