Vulnerability details
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to improper access control in the web-accessible /Images/Person/ and /Images/Family/ directories when requesting predictable static file paths for uploaded photos. A remote attacker can request crafted direct file paths to disclose sensitive information.
Uploaded person and family photos are intended to be retrieved through authenticated API endpoints, but numeric entity IDs are used as filenames for directly served PNG files.
