Severity by source
AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
Remote unauthenticated network trigger (AV:N/PR:N/UI:N); AC:H because exploitation depends on the non-default UrlRoot configuration; pure availability crash so C:N/I:N/A:H.

3DescriptionNVD
A flaw was found in cockpit-ws. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending a specially crafted request. When the WebService.UrlRoot is configured and a request is made to the exact URL-root prefix without a trailing slash, cockpit-ws can terminate unexpectedly. This issue leads to the unavailability of the Cockpit web service.
AnalysisAI
Denial of service in Red Hat's cockpit-ws web service lets a remote, unauthenticated attacker crash the process by sending a request to the exact configured WebService.UrlRoot prefix without a trailing slash, taking the Cockpit management interface offline. The flaw is only reachable on installations that have explicitly set the non-default WebService.UrlRoot option; default deployments are unaffected, and impact is availability-only with no data exposure or code execution. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that cockpit-ws be deployed with the non-default WebService.UrlRoot option configured; the attacker then sends a request to the exact configured URL-root prefix with no trailing slash to trigger the crash. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but bounded issue. … 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 | No vendor-released patch identified at time of analysis: the supplied references (https://access.redhat.com/security/cve/CVE-2026-91147 and https://bugzilla.redhat.com/show_bug.cgi?id=2479230) provide no fixed version or errata identifier, so check the Red Hat CVE page and advisory 2479230 for an updated cockpit-ws package before assuming a fix is unavailable. … Detailed patch versions, workarounds, and compensating controls in full report. |
