CVE-2026-45778: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ubccr xdmod
OpenXDMoD is an open framework for collecting and analyzing HPC metrics. Prior to version 11.0.3, an authenticated attacker can inject malicious JavaScript into their Open XDMoD user profile and abuse the password reset functionality to email a link to an HTML page, which when visited by the victim, reflects and executes the unsanitized payload in the victim's browser, potentially leading to credential capture and Open XDMoD account takeover. All deployments of Open XDMoD prior to 11.0.3 are impacted. This issue was reported privately on 2026-04-06, and at this time there is no evidence that this vulnerability has been exploited in the wild. The vulnerability was patched in Open XDMoD 11.0.3 on 2026-05-12. As a workaround, apply the patch manually.
AI Analysis
Technical Summary
CVE-2026-45778 is a CWE-79 cross-site scripting vulnerability in Open XDMoD before version 11.0.3. An authenticated attacker can inject malicious JavaScript into their user profile and exploit the password reset feature to send a crafted email containing a link to an HTML page that reflects and executes the unsanitized payload in the victim's browser. This can result in credential capture and account takeover. The issue was privately reported on 2026-04-06 and patched in version 11.0.3 released on 2026-05-12. There is no evidence of exploitation in the wild.
Potential Impact
Successful exploitation allows an authenticated attacker to execute arbitrary JavaScript in the context of the victim's browser via a reflected XSS attack. This can lead to credential theft and compromise of Open XDMoD user accounts. The vulnerability affects all deployments prior to version 11.0.3.
Mitigation Recommendations
Apply the official patch by upgrading Open XDMoD to version 11.0.3 or later. As a workaround, manually apply the patch if immediate upgrade is not possible. No other vendor advisories indicate alternative mitigations or that the issue is already mitigated.
