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.

CVE-2026-44431

A flaw was found in urllib3, an HTTP client library for Python. When using the low-level API via `ProxyManager.connection_from_url().urlopen()` with `assert_same_host=False`, cross-origin redirects can still forward sensitive headers. This could allow a remote attacker to gain unauthorized access to sensitive information.

CVE-2026-44432

A flaw was found in urllib3, an HTTP client library for Python. This vulnerability allows a remote attacker to cause excessive resource consumption, such as high CPU usage and massive memory allocation, on the client side. This occurs when urllib3 attempts to decompress an entire HTTP response, even if only a partial read was requested, or when draining the connection after a partial decompression. This can lead to a Denial of Service (DoS) condition.

CVE-2026-45409

A flaw was found in the idna library, which handles Internationalized Domain Names in Python applications. A remote attacker could exploit this vulnerability by sending specially crafted, excessively long inputs to the library's encoding function. This could cause the system to consume significant resources, leading to a Denial of Service (DoS), where the affected application becomes unavailable to legitimate users. This issue stems from an incomplete fix for a previously identified vulnerability.

CVE-2026-48990

A flaw was found in joserfc, a Python library for JSON Object Signing and Encryption (JOSE). This vulnerability allows a remote attacker to cause resource exhaustion, leading to a Denial of Service (DoS), by sending oversized JSON Web Signature (JWS) payloads. The library fails to apply size limits, specifically JWSRegistry.max_payload_length, when processing RFC7797 b64=false JWS payloads.
