fzf vulnerable to denial of service through quadratic HTTP request-body accumulation

fzf is vulnerable to a Denial of Service DoS due to inefficient HTTP body processing in the --listen mode due to inefficient HTTP body processing using repeated string concatenation, resulting in quadratic time complexity On². A crafted POST request with many small segments can trigger excessive...

Inefficient Algorithmic Complexity

Overview Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity in the --listen process due to inefficient HTTP body processing using repeated string concatenation, which results in quadratic time complexity. An attacker can cause excessive CPU usage and monopolize...
