CVE-2025-1835Network attack vector

Authenticated dangerous-file upload via API handler

Published Mar 2, 2025 · Updated Mar 3, 2025

Unrestricted file upload in osuuu LightPicture 1.2.2 allows remote authenticated users to upload dangerous files through its API. The upload function in app/controller/Api.php accepts a manipulated file argument without enforcing the intended upload restriction; public records do not identify the omitted validation check. A valid low-privilege session is required, and public sources do not establish code execution or disclose the uploaded file's storage path.
