CVE-2026-92116Network attack vectorHinoki check available

Open redirect via unchecked OAuth1 callback

Published Oct 12, 2026 · Updated Oct 12, 2026

Open redirect in Apache Allura 1.21.0 and earlier allows remote authenticated users to redirect browsers via OAuth1 callbacks. The OAuth1 flow accepts a caller-supplied callback without matching it against registered redirect URLs. A registered OAuth1 application and user authorization are required; the documented impact is redirection to an untrusted site.
