With follow_redirect enabled, hackney:follow_redirect/10 in src/hackney.erl reissues the request to the Location target after hackney:maybe_strip_auth_on_redirect/3, which compared only the hostname of the current and the redirect URL. A redirect from https to http on the same host resent the Authorization and Cookie headers in cleartext, where an on-path attacker can read them, and a redirect to another port on the same host handed them to a different service. location_trusted forwards credentials to any target by design and is unchanged.\n\nThis issue affects hackney: from 2.0.0 before 4.9.0.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-522"],"vendors":[],"products":[],"references":[{"url":"https://cna.erlef.org/cves/CVE-2026-113440.html","tags":[]},{"url":"https://github.com/benoitc/hackney/commit/6548384b22ea196023a1963e2967d5715b6d9564","tags":[]},{"url":"https://github.com/benoitc/hackney/commit/8f944559bdb83da60b5c06f6cf6d842591278364","tags":[]},{"url":"https://github.com/benoitc/hackney/pull/979","tags":[]},{"url":"https://github.com/benoitc/hackney/releases/tag/4.9.0","tags":[]},{"url":"https://osv.dev/vulnerability/EEF-CVE-2026-113440","tags":[]}],"exploitRefs":[{"url":"https://github.com/benoitc/hackney/commit/6548384b22ea196023a1963e2967d5715b6d9564","tags":[]},{"url":"https://github.com/benoitc/hackney/commit/8f944559bdb83da60b5c06f6cf6d842591278364","tags":[]},{"url":"https://github.com/benoitc/hackney/pull/979","tags":[]},{"url":"https://github.com/benoitc/hackney/releases/tag/4.9.0","tags":[]}],"hasPoc":true,"ai":null}
