fzf 0.36.0 through 0.74.5 contains an inefficient algorithmic complexity vulnerability in maskActionContents that allows local attackers to exhaust the --listen HTTP server through quadratic string concatenation. Attackers can repeatedly send POST bodies of about 1 MB to the unauthenticated localhost port, blocking the single-threaded server for about 30 seconds each time.
