This link is maintained to preserve external references.\n\n## Original Description\n\nguzzlehttp/guzzle versions before 7.15.1 contain an information disclosure vulnerability in RedirectMiddleware. When the optional allow_redirects.referer setting is enabled, the middleware copies the URI fragment (the portion after '#') from the referring request into the generated Referer header when following a same-scheme redirect (e.g., HTTPS to HTTPS). An attacker who controls the redirect destination can read this fragment from the incoming Referer header, potentially disclosing one-time login secrets, access tokens, state values, or other sensitive client data to a server never meant to receive it. The referer setting is disabled by default. Fixed in 7.15.1, which strips the fragment before generating the Referer value.","public_affected_ranges":["ECOSYSTEM: introduced 0"]}],"null_published_at":"2026-10-31T21:53:28.063Z","source_updated_at":"2026-09-10T03:51:14.546Z","source_disclosed_at":"2026-08-01T15:30:30.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:42:30.982Z"}],"next_cursor":null,"snapshot_revision":"42594"}
