CVE-2026-42151 is a credential-disclosure vulnerability in the Azure AD remote-write OAuth configuration of Prometheus. The OAuthConfig.ClientSecret field is typed as a plain string rather than the Secret type used for configuration redaction. Consequently, the configuration HTTP API returns the Azure OAuth client secret in plaintext to any user or process able to access it. The issue is fixed in Prometheus 3.5.3 LTS and 3.11.3.
