AI-suggested
Upgrade to HTTP::Body version 1.25 or later, which limits the size and number of lines in the trailer and mitigates the quadratic parsing time vulnerability. No other mitigation is indicated.
Description
HTTP::Body versions before 1.24_02 for Perl have a performance vulnerability where parsing the trailer section occurs in quadratic time relative to the number of repeated header fields. This can cause excessive CPU usage when processing specially crafted requests with many repeated trailer fields. Version 1.25 mitigates this by limiting the size and number of lines in the trailer.
