With $CGI::DISABLE_UPLOADS set, it discards the body by reading until Content-Length bytes have arrived. Once a body shorter than its Content-Length runs out, every read returns 0, so the loop never ends.\n\nA client can keep a server process spinning with one such request.","epss":null,"exploits":[],"kev":null,"metrics":[],"modifiedAt":1793749277179,"publishedAt":1793749277179,"references":[{"source":"CNA: CPANSec","tags":["technical-description"],"url":"https://metacpan.org/release/LEEJO/CGI-4.72/source/lib/CGI.pm"},{"source":"CNA: CPANSec","tags":["release-notes"],"url":"https://metacpan.org/release/LEEJO/CGI-5.00/changes"},{"source":"CNA: CPANSec","tags":["patch"],"url":"https://github.com/leejo/CGI.pm/commit/16d9f61acf8b844b7360e8d726338e3ce34dfa9f.patch"},{"source":"CNA: CPANSec","tags":["patch"],"url":"https://github.com/leejo/CGI.pm/commit/8a78305065690461ae283fa24e5ebe4ec8a22fbc.patch"}],"remediation":[{"kind":"fix","source":"CNA: CPANSec","text":"Upgrade to CGI 5.00 or later."},{"kind":"fix","source":"CNA: CPANSec","text":"The reporting source identifies this reference as a patch.
