Description

OpenAM Reflected XSS in the OAuth2/OIDC wap consent page

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=wap authorize links as untrusted.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality low, integrity low, availability none.

Weakness class

CVE-2026-62280 is classified as CWE-79: Cross-site Scripting (XSS). User-supplied data is written into a page without escaping, so attacker script runs in the browser of anyone who views it.

CVE-2026-62280 is recorded against 1 package.
