Unauthenticated sensitive data exposure in Bookly plugin versions ≤27.4 allows attackers to view confidential information.
Vulnerability
Bookly, a WordPress appointment booking plugin, versions up to and including 27.4 contain an unauthenticated sensitive data exposure vulnerability [1]. The issue allows any unauthenticated user to access information that should be restricted to authorized users only.
Exploitation
An attacker can exploit this vulnerability by sending a crafted HTTP request to the vulnerable endpoint, without requiring any prior authentication or user interaction [1]. This can be done remotely by anyone with network access to the site.
Impact
Successful exploitation leads to exposure of sensitive data that is normally hidden from regular users [1]. This could include client information, appointment details, or other confidential records, potentially enabling further attacks or privacy violations.
Mitigation
The vulnerability is fixed in version 27.5 or later. Users are advised to update the plugin immediately [1]. For those unable to update, Patchstack offers a mitigation rule that blocks attacks until the update is applied [1].
