CVE-2026-105114: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in OpenIdentityPlatform OpenAM
OpenAM before 16.1.3 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject script by supplying crafted parameters rendered unencoded on the OAuth2 authorization error page. Attackers can lure victims to a crafted /oauth2/authorize link with repeated parameters to run JavaScript in the OpenAM origin, acting within existing sessions or redirecting to phishing pages.
AI Analysis
Technical Summary
CVE-2026-105114 is a reflected XSS vulnerability in OpenIdentityPlatform's OpenAM prior to version 16.1.3. The vulnerability arises because input parameters supplied to the OAuth2 authorization error page are rendered without proper encoding, allowing injection of arbitrary JavaScript. Attackers can exploit this by crafting URLs with repeated parameters that trigger script execution when visited by victims, potentially compromising session integrity or facilitating phishing attacks.
Potential Impact
Successful exploitation allows execution of arbitrary JavaScript in the context of the vulnerable OpenAM instance. This can lead to session hijacking, unauthorized actions within the user's session, or redirection to malicious phishing pages. The vulnerability requires user interaction (visiting a crafted URL) but does not require authentication.
Mitigation Recommendations
A fix is available in OpenAM version 16.1.3. Users should upgrade to version 16.1.3 or later to remediate this vulnerability. No additional mitigation steps are indicated in the provided data.
