CVE-2022-1902Public exploitNetwork attack vector

Privilege escalation via unsanitized GraphQL notifier retrieval

Published Sep 1, 2022 · Updated Aug 3, 2024

Information disclosure in Red Hat Advanced Cluster Security for Kubernetes 3 allows remote authenticated users to retrieve notifier secrets. GraphQL notifier queries used datastore paths that returned full notifier objects without applying the secret-scrubbing logic used by other retrieval paths. Any authenticated ACS account able to retrieve notifiers can obtain credentials such as PagerDuty API keys and use their downstream permissions to escalate access.
