CVE-2025-59716 Medium · 5.3 Public exploit CWE-200 Nov 5, 2025
Exposure of Sensitive Information in Owncloud Guests
ownCloud Guests before 0.12.5 allows unauthenticated user enumeration via the /apps/guests/register/{email}/{token} endpoint. Because of insufficient validation of the supplied token in showPasswordForm, the server responds differently when an e-mail address corresponds to a valid pending guest user rather than a non-existent user.
