CVE-2026-45778 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. 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. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
