AIOHTTP: Multipart Header Size Bypass
Summary
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, a response with an excessive number of multipart headers may be allowed to use more memory than intended, potentially allowing a DoS vulnerability. This issue has been patched in version 3.13.4.

AIOHTTP: Late size enforcement for non-file multipart fields causes memory DoS
Summary
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, for some multipart form fields, aiohttp read the entire field into memory before checking client_max_size. This issue has been patched in version 3.13.4.

Summary
urllib3 is an HTTP client library for Python. From 1.23 to before 2.7.0, cross-origin redirects followed from the low-level API via ProxyManager.connection_from_url().urlopen(..., assert_same_host=False) still forward these sensitive headers. This vulnerability is fixed in 2.7.0.

Title
urllib3: Decompression-bomb safeguards bypassed in parts of the streaming API
Summary
urllib3 is an HTTP client library for Python. From 2.6.0 to before 2.7.0, urllib3 could decompress the whole response instead of the requested portion (1) during the second HTTPResponse.read(amt=N) call when the response was decompressed using the official Brotli library or (2) when HTTPResponse.drain_conn() was called after the response had been read and decompressed partially (compression algorithm did not matter here). These issues could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This could result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data) on the client side. This vulnerability is fixed in 2.7.0.

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
critcarries 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

When a JWS token contains a `crit` array listing\nextensions that PyJWT does not understand, the library accepts the token\ninstead of rejecting it. This violates the **MUST** requirement in the RFC.\n\nThis is the same class of vulnerability as CVE-2025-59420 (Authlib),\nwhich received CVSS 7.5 (HIGH).\n\n---\n\n## RFC Requirement\n\nRFC 7515 \u00a74.1.11:\n\n\u003e The \"crit\" (Critical) Header Parameter indicates that extensions to this\n\u003e specification and/or [JWA] are being used that **MUST** be understood and\n\u003e processed. [...] If any of the listed extension Header Parameters are\n\u003e **not understood and supported** by the recipient, then the **JWS is invalid**.\n\n---\n\n## Proof of Concept\n\n```python\nimport jwt # PyJWT 2.8.0\nimport hmac, hashlib, base64, json\n\n# Construct token with unknown critical extension\nheader = {\"alg\": \"HS256\", \"crit\": [\"x-custom-policy\"], \"x-custom-policy\": \"require-mfa\"}\npayload = {\"sub\": \"attacker\", \"role\": \"admin\"}\n\ndef b64url(data):\n return base64.urlsafe_b64encode(data).rstrip(b\"=\").decode()\n\nh = b64url(json.dumps(header, separators=(\",\", \":\")).encode())\np = b64url(json.dumps(payload, separators=(\",\", \":\")).encode())\nsig = b64url(hmac.new(b\"secret\", f\"{h}.{p}\".encode(), hashlib.sha256).digest())\ntoken = f\"{h}.{p}.{sig}\"\n\n# Should REJECT \u2014 x-custom-policy is not understood by PyJWT\ntry:\n result = jwt.decode(token, \"secret\", algorithms=[\"HS256\"])\n print(f\"ACCEPTED: {result}\")\n # Output: ACCEPTED: {\u0027sub\u0027: \u0027attacker\u0027, \u0027role\u0027: \u0027admin\u0027}\nexcept Exception as e:\n print(f\"REJECTED: {e}\")\n```\n\n**Expected:** `jwt.exceptions.InvalidTokenError: Unsupported critical extension: x-custom-policy`\n**Actual:** Token accepted, payload returned.\n\n### Comparison with RFC-compliant library\n\n```python\n# jwcrypto \u2014 correctly rejects\nfrom jwcrypto import jwt as jw_jwt, jwk\nkey = jwk.JWK(kty=\"oct\", k=b64url(b\"secret\"))\njw_jwt.JWT(jwt=token, key=key, algs=[\"HS256\"])\n# raises: InvalidJWSObject(\u0027Unknown critical header: \"x-custom-policy\"\u0027)\n```\n\n---\n\n## Impact\n\n- **Split-brain verification** in mixed-library deployments (e.g., API\n gateway using jwcrypto rejects, backend using PyJWT accepts)\n- **Security policy bypass** when `crit` carries enforcement semantics\n (MFA, token binding, scope restrictions)\n- **Token binding bypass** \u2014 RFC 7800 `cnf` (Proof-of-Possession) can be\n silently ignored\n- See CVE-2025-59420 for full impact analysis\n\n---\n\n## Suggested Fix\n\nIn `jwt/api_jwt.py`, add validation in `_validate_headers()` or\n`decode()`:\n\n```python\n_SUPPORTED_CRIT = {\"b64\"} # Add extensions PyJWT actually supports\n\ndef _validate_crit(self, headers: dict) -\u003e None:\n crit = headers.get(\"crit\")\n if crit is None:\n return\n if not isinstance(crit, list) or len(crit) == 0:\n raise InvalidTokenError(\"crit must be a non-empty array\")\n for ext in crit:\n if ext not in self._SUPPORTED_CRIT:\n raise InvalidTokenError(f\"Unsupported critical extension: {ext}\")\n if ext not in headers:\n raise InvalidTokenError(f\"Critical extension {ext} not in header\")\n```\n\n---\n\n## CWE\n\n- CWE-345: Insufficient Verification of Data Authenticity\n- CWE-863: Incorrect Authorization\n\n## References\n\n- [RFC 7515 \u00a74.1.11](https://www.rfc-editor.org/rfc/rfc7515.html#section-4.1.11)\n- [CVE-2025-59420 \u2014 Authlib crit bypass (CVSS 7.5)](https://osv.dev/vulnerability/GHSA-9ggr-2464-2j32)\n- [RFC 7800 \u2014 Proof-of-Possession Key Semantics](https://www.rfc-editor.org/rfc/rfc7800)",

Summary
Tornado has incomplete validation of cookie attributes
Details
Values passed to the domain, path, and samesite arguments of RequestHandler.set_cookie were not completely validated in versions of Tornado prior to 6.5.5. In particular, semicolons would be allowed, which could be used to inject attacker-controlled values for other cookie attributes.
Severity
5.4 (Medium)
