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.
