How to Fix CVE-2026-62280
To remediate this vulnerability, upgrade all affected Openam oauth2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.openidentityplatform.openam</groupId>
<artifactId>openam-oauth2</artifactId>
<version>16.1.2</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.openidentityplatform.openamHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-62280, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.openidentityplatform.openamAnalyze the terminal output to locate any version of Openam oauth2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 16.1.2), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.openidentityplatform.openam command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Openam oauth2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Description\nThe 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.\n\nThis is the same vulnerability class as CVE-2026-44203; that fix did not cover this code path.\n\n### Impact\nArbitrary 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.\n\n### Mitigation\n- Upgrade to 16.1.2 (or later).\n- Until then, restrict/limit access to the OAuth2 authorize endpoint and treat unsolicited `display=wap` authorize links as untrusted.",
