Medium (5.4) in 9001 copyparty. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in copyparty 1.20.11.
Copyparty is a portable file server. Prior to v1.20.11., the nohtml config option, intended to prevent execution of JavaScript in user-uploaded HTML files, did not apply to SVG images. A user with write-permission could upload an SVG containing embedded JavaScript, which would execute in the context of whichever user opens it. This has been fixed in v1.20.11.
