CVE-2023-50265
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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. This issue is fixed in version 1.3.1.
