{"id":"CVE-2026-120651","published":"2026-11-04T00:17:26.633","lastModified":"2026-11-04T00:17:26.633","description":"CGI versions before 5.00 for Perl allow an infinite loop on a short request body when $DISABLE_UPLOADS is set.\n\nWhen $CGI::PUTDATA_UPLOAD or an upload hook is set, read_postdata_putdata takes a request body that is not a form submission. 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-835"],"vendors":[],"products":[],"references":[{"url":"https://github.com/leejo/CGI.pm/commit/16d9f61acf8b844b7360e8d726338e3ce34dfa9f.patch","tags":[]},{"url":"https://github.com/leejo/CGI.pm/commit/8a78305065690461ae283fa24e5ebe4ec8a22fbc.patch","tags":[]},{"url":"https://metacpan.org/release/LEEJO/CGI-4.72/source/lib/CGI.pm","tags":[]},{"url":"https://metacpan.org/release/LEEJO/CGI-5.00/changes","tags":[]}],"exploitRefs":[{"url":"https://github.com/leejo/CGI.pm/commit/16d9f61acf8b844b7360e8d726338e3ce34dfa9f.patch","tags":[]},{"url":"https://github.com/leejo/CGI.pm/commit/8a78305065690461ae283fa24e5ebe4ec8a22fbc.patch","tags":[]}],"hasPoc":true,"ai":null}
