CVE-2026-42151

A flaw was found in Prometheus, an open-source monitoring system. The `client_secret` field within the Azure Active Directory (AD) remote write OAuth configuration was incorrectly handled as a plain string instead of a secure Secret type. This misconfiguration allowed any user or process with access to the `/-/config` HTTP API endpoint to view the Azure OAuth client secret in plaintext. This vulnerability leads to information disclosure, potentially compromising the security of integrated Azure AD services.

CVE-2026-42154

A flaw was found in Prometheus. An unauthenticated attacker can exploit the remote read endpoint (`/api/v1/read`) by sending a specially crafted, small snappy-compressed payload. This payload causes a disproportionately large memory allocation, leading to memory exhaustion and a Denial of Service (DoS) by crashing the Prometheus process.
