CVE-2026-108950
Open Source Social Network (OSSN) through 10.1 contains a missing authorization vulnerability in ossn_album_page_handler that allows unauthenticated attackers to download files via album/getphoto and album/getcover.
Does this matter?
Lower severity and a low EPSS score (0.33%). Track it; it rarely justifies an emergency change on its own.
