Summary
copyparty allows Regex Denial of Service (ReDoS) in the upload listing
Details

Summary

The filter parameter for the "Recent uploads" page allows arbitrary Regexes. If this feature is enabled (which is the default), an attacker can craft a filter which deadlocks the server.

PoC

https://127.0.0.1:3923/?ru&filter=(.+)+x

Impact

The server becomes fully inaccessible for a long time.
