Credential disclosure via retained redirect headers
Published Nov 11, 2024 · Updated Nov 12, 2024
Information disclosure in affected Moodle LMS releases allows attackers to receive HTTP authorization headers through cross-host redirects. The cURL wrapper's emulated redirect path clears HTTPAUTH and USERPWD but reuses CURLOPT_HTTPHEADER without removing Authorization on a different host. Exposure requires a Moodle cURL request carrying that header to follow a cross-host redirect; affected lines end at 4.1.11, 4.2.8, 4.3.5, and 4.4.1.
