AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Unauthenticated network stored-XSS (PR:N/AV:N/AC:L) needs a victim to view the console (UI:R); admin-session/cluster takeover crosses scope (S:C) with high C/I, but A:H is overstated for XSS so A:L.
Primary rating from Vendor (suse).

An unauthenticated update of public UI settings could be used by remote attackers to execute a stored cross-site scripting attack in the Rancher UI, in SUSE Rancher 2.15 before 2.15.2, 2.14 before 2.14.6, 2.13 before 2.13.10, 2.12 before 2.12.14 and 2.11 before 2.11.18.

AnalysisAI
Stored cross-site scripting in the SUSE Rancher UI allows unauthenticated remote attackers to inject malicious script through updates to public UI settings, which then executes in the browser of any user-including administrators-who later views the affected interface. Affected versions are SUSE Rancher 2.15 before 2.15.2, 2.14 before 2.14.6, 2.13 before 2.13.10, 2.12 before 2.12.14, and 2.11 before 2.11.18. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the Rancher instance expose the update of 'public UI settings' to unauthenticated callers (the described default behavior of the affected versions), and that a victim - realistically a Rancher administrator or user - subsequently load the Rancher UI so the stored payload renders and executes (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Vendor CVSS 3.1 rates this 9.6 (Critical) with vector AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H - network-reachable, low-complexity, no privileges, requiring only that a victim view the page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: SUSE Rancher 2.15.2, 2.14.6, 2.13.10, 2.12.14, and 2.11.18. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all SUSE Rancher deployments and determine whether any run 2.15 before 2.15.2, 2.14 before 2.14.6, 2.13 before 2.13.10, 2.12 before 2.12.14, or 2.11 before 2.11.18; because exploitation requires network reachability to the Rancher management endpoint, immediately restrict that endpoint to trusted administrative networks, VPN, or bastion access and remove any public internet exposure, then audit current UI public settings for unexpected or injected content and force re-authentication of administrative sessions. …
