CVE-2026-45296 OpenReplay: Cross-tenant information disclosure in app_apikey projectKey routes via missing tenant binding

OpenReplay is a self-hosted session replay suite. Prior to 1.26.0, OpenReplay's Python API exposes several appapikey routes that trust a caller-provided projectKey after validating only that the API key itself is valid and that the target projectKey exists. The authorization flow does not verify...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via the jwt.decode or jwt.decodecomplete functions when used with a PyJWK key. An attacker can bypass algorithm restrictions and gain unauthorized access to protected resources by signing...

Unintended Proxy or Intermediary ('Confused Deputy')

Overview Affected versions of this package are vulnerable to Unintended Proxy or Intermediary 'Confused Deputy' via the uri parameter being passed directly to urllib.request.urlopen, which allows fetching resources using unsupported schemes such as file, ftp, and data. An attacker can access...

Improper Cleanup on Thrown Exception

Overview Affected versions of this package are vulnerable to Improper Cleanup on Thrown Exception via the getsigningkey function. An attacker can exhaust system resources by sending numerous JWTs with attacker-controlled kid values, causing repeated outbound requests to the JWKS endpoint. Note:...

Improper Authentication

Overview Affected versions of this package are vulnerable to Improper Authentication when decoding JSON Web Tokens. An attacker can forge valid tokens by supplying a public key as the secret for the HMAC algorithm when both asymmetric and HMAC algorithms are supported. PoC python from jwt.apijws...

PYSEC-2026-177

PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, PyJWKClient.getsigningkey forces a fresh HTTP request to the JWKS endpoint for every JWT with an unknown kid value, with no rate limiting. Since kid comes from the unverified token header, an attacker can trigger unlimited...

PYSEC-0000-CVE-2026-48523

PyJWT is a JSON Web Token implementation in Python. From 2.9.0 to 2.12.1, there is a verifier-side algorithm allow-list bypass when jwt.decode or jwt.decodecomplete are called with a PyJWK key. The token header alg is checked against the caller-supplied algorithms allow-list, but signature...

DEBIAN-CVE-2026-48526

PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, when the verifier is decoding JSON Web Tokens, while supporting both asymmetric and HMAC algorithms, the library does not validate use of JSON Web Keys in HMAC algorithm, allowing attacker to use the issuer public key as the...

CVE-2026-44593

esm.sh is a no-build content delivery network CDN for web development. In 137 and earlier, the legacy router first retrieves a response from legacyServer, parses the incoming request path, and ultimately writes the data to storage via buildStorage.Put. The router concatenates the path components...
