Severity
5.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L
Summary
Lara Dashboard before 1.3.2 fails to authorize access to the post-builder image and video upload endpoints, allowing authenticated accounts without content permissions to upload files. Attackers can upload polyglot files with attacker-chosen extensions to the public web root and execute code if the deployment permits execution of the uploaded file type.
