Cross-Site Scripting (XSS) in org.openidentityplatform.openam:openam-oauth2 (CVE-2026-62280)
Summary
Cross-site scripting in org.openidentityplatform.openam:openam-oauth2 (CVE-2026-62280). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 16.1.2 or later.
Original description
The description as published by the source.
Description
The OAuth2/OIDC consent page rendered for display=wap authorize requests reflected several request-derived values into the HTML response without escaping. An attacker who induces a user with an active OpenAM session to follow a crafted authorize link can execute arbitrary JavaScript in the OpenAM origin.
This is the same vulnerability class as CVE-2026-44203; that fix did not cover this code path.
Impact
Arbitrary JavaScript execution in the OpenAM origin in the victim's authenticated context — enabling session/cookie theft, CSRF-token exfiltration, and actions on behalf of the victim, up to administrative takeover if the victim is an administrator. Reachable on any deployment with at least one registered OAuth2 client; no attacker-controlled client and no special configuration required.
Mitigation
- Upgrade to 16.1.2 (or later).
- Until then, restrict/limit access to the OAuth2 authorize endpoint and treat unsolicited
display=wapauthorize links as untrusted.
