A double extension technique allows an authenticated user with author or higher privileges to upload files that bypass the VTT sanitization and are stored on the server. This flaw can be used to place malicious scripts or other executable files, potentially leading to remote code execution if the attacker can subsequently invoke the uploaded file.", "risk_and_exploitability": "The flaw carries a CVSS score of 8.8, indicating high severity. The EPSS score of less than 1% suggests that exploitation is currently unlikely, and it is not listed in the CISA KEV catalog.
