CVE-2020-10752Network attack vector

Account impersonation via panic-log OAuth token disclosure

Published Jun 12, 2020 · Updated Aug 4, 2024

Credential disclosure in Red Hat OpenShift API Server allows remote authenticated users to obtain OAuth tokens from panic logs. The panic-recovery path writes OAuthToken identifiers containing usable token values to API server logs instead of nonsecret hashes. Exploitation requires the ability to trigger an API server error and read control-plane logs; a recovered token grants its holder that token's API access.
