Mongoose is an embedded web server and network library. Prior to 7.23, a network attacker can impersonate a TLS server to a Mongoose client configured with a multi-certificate CA bundle. In src/tlsbuiltin.c, the mgtlsinit function stores the bundle in tls-cabundleder while tls-cader.len remains...

CVE-2026-73251 Mongoose Built-in TLS: CA-bundle certificate chain accepted without any signature verification

Mongoose is an embedded web server and network library. Prior to 7.23, a network attacker can impersonate a TLS server to a Mongoose client configured with a multi-certificate CA bundle. In src/tlsbuiltin.c, the mgtlsinit function stores the bundle in tls-cabundleder while tls-cader.len remains...

CVE-2026-73251

Mongoose (embedded web server and network library) prior to 7.23 contains a critical TLS certificate verification flaw in src/tls_builtin.c. When a client is configured with a multi-certificate CA bundle, mg_tls_init() stores the bundle in tls->ca_bundle_der while tls->ca_der.len remains ze...

CVE-2026-9697

Impact: undici's ProxyAgent silently drops the requestTls option when configured with a SOCKS5 proxy URI socks5:// or socks://. The target HTTPS connection through the SOCKS5 tunnel falls back to Node's default trust store, ignoring user-configured ca, cert, key, rejectUnauthorized, and servernam...

CVE-2026-40944

Oxia is a metadata store and coordination system. Prior to 0.16.2, the trustedCertPool function in the TLS configuration only parses the first PEM block from CA certificate files. When a CA bundle contains multiple certificates e.g., intermediate + root CA, only the first certificate is loaded...

Oxia's TLS CA certificate chain validation fails with multi-certificate PEM bundles

Summary The trustedCertPool function in the TLS configuration only parses the first PEM block from CA certificate files. When a CA bundle contains multiple certificates e.g., intermediate + root CA, only the first certificate is loaded. This silently breaks certificate chain validation for mTLS...

CVE-2026-25645

Requests is a HTTP library. Prior to version 2.33.0, the requests.utils.extractzippedpaths utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker...

CVE-2026-25645 Requests has Insecure Temp File Reuse in its extract_zipped_paths() utility function

Requests is a HTTP library. Prior to version 2.33.0, the requests.utils.extractzippedpaths utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker...

CVE-2026-25645

The CVE describes an insecure temp-file extraction in the Requests library prior to v2.33.0. The vulnerable function requests.utils.extract_zipped_paths() writes the CA bundle into /tmp using a predictable, non-unique filename (e.g., cacert.pem) and reuses an existing file if present, rather than...
