Open Source Social Network (OSSN) versions up to 10.1 have a missing authorization vulnerability in the ossn_album_page_handler component. This flaw allows unauthenticated attackers to download files via album/getphoto and album/getcover endpoints. Attackers can enumerate sequential file GUIDs to access friends-only album photos and other stored files without any access control checks. The vulnerability has a CVSS 3.1 score of 5.3, indicating medium severity.

Open Source Social Network (OSSN) versions through 10.1 have an insecure direct object reference (IDOR) vulnerability in the ossn_com.php component of OssnMessages. This flaw allows authenticated users to access private message attachments of other users by requesting attachments via the /messages/attachment/{guid} endpoint without proper sender or recipient verification. The vulnerability enables unauthorized reading of private message attachments.

OSSN (Open Source Social Network) 8.6 is vulnerable to SQL Injection in /action/rtcomments/status via the timestamp parameter.

Open Source Social Network (OSSN) 8.6 is vulnerable to Cross Site Scripting (XSS) via the parameter param` at endpoint u/administrator/friends.
