What is CVE-2026-81652?
CVE-2026-81652 is a low-severity missing authorization vulnerability in Unknown Photo Gallery, Sliders, Proofing and Themes, published on 20 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
The Photo Gallery, Sliders, Proofing and WordPress plugin before 4.5.0 does not verify that the requesting user is entitled to a given image record before returning it, allowing users with the Contributor role and above to read the stored metadata of any image on the site, including images in galleries belonging to other users. The disclosed data includes the image's stored EXIF subset, covering camera make and model and capture timestamp, along with internal checksums and identifiers that the Photo Gallery, Sliders, Proofing and WordPress plugin before 4.5.0's own capability-gated read path reserves to administrators.
