AnalysisAIv1 – Sep 15, 2026

Cross-site scripting (CWE-79) in IBM Verify Identity Access 11.0.0 through 11.0.3 Interim Fix 001 and IBM Security Verify Access 10.0.0 through 10.0.9.2 Interim Fix 001, including the corresponding container editions, allows a remote unauthenticated attacker to run script in the browser of a logged-in user who follows a crafted link, potentially hijacking an authenticated session or performing actions as that user. The CVSS 3.1 base score is 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N), which reflects the need for victim interaction and the limited but scope-changing confidentiality and integrity impact typical of reflected XSS. There is no public exploit code identified at time of analysis, no confirmed active exploitation (not in CISA KEV), and the EPSS probability is only 0.20% (10th percentile), so this is a patching-hygiene issue rather than an emergency response item.

What every action level means
Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.
Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.
This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.
This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.
Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
