Prior to versions 3.5.3 and 3.11.3, the client_secret field in the Azure AD remote write OAuth configuration (storage/remote/azuread) was typed as string instead of Secret. Prometheus redacts fields of type Secret when serving the configuration via the /-/config HTTP API endpoint. Because the field was a plain string, the Azure OAuth client secret was exposed in plaintext to any user or process with access to that endpoint. This issue has been patched in versions 3.5.3 and 3.11.3.</p> <p><strong>Affected:</strong> prometheus, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 10.0 Extended Update Support, Red Hat Enterprise Linux 9, Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions, Red Hat Enterprise Linux 9.6 Extended Update Support, Red Hat RHEM 1.0 for RHEL 9, Red Hat RHEM 1.1 for RHEL 10, Red Hat RHEM 1.1 for RHEL 9, Red Hat Logging for Red Hat OpenShift 6 and 45 more</p> <p>Prometheus is an open-source monitoring system and time series database.

An unauthenticated attacker can send a small payload that causes a huge heap allocation per request. Under concurrent load this can exhaust available memory and crash the Prometheus process.</p> <p>### Patches _Has the problem been patched? What versions should users upgrade to?_</p> <p>Fixed in 3.11.3 and 3.5.3 LTS. Users should upgrade to these versions or later.</p> <p>### Workarounds User who can not upgrade can place Prometheus behind a reverse proxy or firewall that requires authentication before requests reach /api/v1/read.</p> <p><strong>Affected:</strong> Go: github.com/prometheus/prometheus</p> <p>### Impact</p> <p>The remote read endpoint (`/api/v1/read`) does not validate the declared decoded length in a snappy-compressed request body before allocating memory.
