7.5
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A memory leak flaw was found in cockpit-ws. The login page handler leaks a heap allocation on every unauthenticated request that carries a CockpitLang cookie, allowing a remote unauthenticated attacker to exhaust memory on the host and cause a denial of service.
Affected Software
| Vendor | Product | Version Range | Status |

Weaknesses
- CWE-401: Missing Release of Memory after Effective Lifetime
Workarounds
Restrict network access to the cockpit port to trusted clients until a fix is available. No configuration-level mitigation removes the flaw entirely, since the login page must remain reachable without authentication.
