Arbitrary file write via unprotected add-asset endpoint
Published Jun 15, 2026 · Updated Jun 15, 2026
Arbitrary file write in Remotion Studio before 4.0.410 allows remote attackers to write files through the add-asset endpoint. The handleAddAsset route accepts an attacker-controlled filePath and request body without a randomized route prefix or same-origin validation. Exploitation requires network access to a running, exposed Remotion Studio server and can overwrite files or interrupt the service.
