{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/82960?format=json","vulnerability_id":"VCID-tfk1-p53r-5ucs","summary":"A security issue was discovered in ingress-nginx where the protection afforded by the `auth-url` Ingress annotation may not be effective in the presence of a specific misconfiguration.\n\nIf the ingress-nginx controller is configured with a default custom-errors configuration that includes HTTP errors 401 or 403, and if the configured default custom-errors backend is defective and fails to respect the X-Code HTTP header, then an Ingress with the `auth-url` annotation may be accessed even when authentication fails.\n\nNote that the built-in custom-errors backend works correctly. To trigger this issue requires an administrator to specifically configure ingress-nginx with a broken external component.","aliases":[{"alias":"CVE-2026-24513"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://github.com/kubernetes/kubernetes/issues/136679","reference_id":"136679","reference_type":"","scores":[{"value":"3.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-02-04T18:20:39Z/"}],"url":"https://github.com/kubernetes/kubernetes/issues/136679"}],"weaknesses":[{"cwe_id":754,"name":"Improper Check for Unusual or Exceptional Conditions","description":"The product does not check or incorrectly checks for unusual or exceptional conditions that are not expected to occur frequently during day to day operation of the product."}],"exploits":[],"severity_range_score":"3.1 - 3.1","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-tfk1-p53r-5ucs"}
