Risk & exploitation
EPSS (FIRST) estimates a elevated likelihood of exploitation in the next 30 days (2026-06-10). Priority blends CVSS, EPSS, KEV and public-exploit availability — operational prioritization, not a NIS2/DORA reporting determination.
Summary
A XSS vulnerability was identified in the ServiceNow UI page assessment_redirect. To exploit this vulnerability, an attacker would need to persuade an authenticated user to click a maliciously crafted URL. Successful exploitation potentially could be used to conduct various client-side attacks, including, but not limited to, phishing, redirection, theft of CSRF tokens, and use of an authenticated user's browser or session to attack other systems.
Auto-generated stub from NVD. Detection signals and per-release fixed-in are pending manual authoring/verification; until a signal carries a verified match, the exposure check returns DORMANT/INVESTIGATE — never a false EXERCISED.Affected releases & fixed-in
