CVE-2023-50265 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Bazarr manages and downloads subtitles. Prior to 1.3.1, the /api/swaggerui/static endpoint in bazarr/app/ui.py does not validate the user-controlled filename variable and uses it in the send_file function, which leads to an arbitrary file read on the system. EPSS estimates a 0.92% chance of exploitation in the next 30 days.
