Unauthenticated file disclosure via predictable upload filenames
Published Aug 10, 2026 · Updated Aug 10, 2026
Information exposure in Contact Form to Any API before 3.0.7 allows remote attackers to download files uploaded by other users. The plugin copies Contact Form 7 uploads into a public directory using a filename composed of the form ID, Unix timestamp, and extension instead of a random token. Exploitation requires an active file-upload form, successful mail delivery, and the default disabled entry-hiding option; attackers can sweep likely timestamps and extensions without authentication.
