CVE-2026-102265 PyJWT: Uncaught RecursionError in jwt.decode() on deeply nested token header

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWS.load in jwt/apijws.py is affected because parser catches ValueError but not RecursionError. This occurs when a deeply nested token header reaches json.loads. As a result, RecursionError escapes the...

CVE-2026-102275

The PyJWT Python library (versions 2.1.0 through 2.15.0 ) is vulnerable in the PyJWT.OKPAlgorithm.from_jwk function within jwt/algorithms.py. The root cause is that the private-JWK import path fails to compare the public key derived from d with x . This allows an attacker to provide non-correspon...

CVE-2026-102275 PyJWT accepts inconsistent OKP x/d JWKs, causing public/private key identity confusion

PyJWT is a Python implementation of JSON Web Token standards. From 2.1.0 until 2.15.0, PyJWT OKPAlgorithm.fromjwk in jwt/algorithms.py is affected because private-JWK import path does not compare the public key derived from d with x. This occurs when an OKP private JWK supplies non-corresponding ...

CVE-2026-102273

The PyJWT Python library (versions 2.13.0 through 2.14.0 ) contains a vulnerability in HMACAlgorithm.prepare_key . The flaw occurs because the HMAC key guard fails to recognize container representations, allowing public JWK containers to be accepted as HMAC secrets when an application supports bo...

CVE-2026-102273

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because HMAC key guard only recognizes top-level public JWK forms and misses container representations. This occurs when an application allows HMAC and asymmetric...

CVE-2026-102273 PyJWT accepts public JWK containers as HMAC secrets

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because HMAC key guard only recognizes top-level public JWK forms and misses container representations. This occurs when an application allows HMAC and asymmetric...

CVE-2026-102272

The PyJWT library (versions 2.13.0 up to 2.14.0) contains a vulnerability in the HMACAlgorithm.prepare_key function within jwt/algorithms.py. The root cause is that the raw-JWK detector fails to normalize accepted Unicode byte-order marks (BOM) before performing JSON checks. When a public JWK is ...

EUVD-2026-88539

PyJWT is a Python implementation of JSON Web Token standards. From 2.4.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because asymmetric-key guard relies on textual markers that are absent from DER encoding. This occurs when an application mixes HMAC and asymmetric algorithms and...

CVE-2026-102270 PyJWT: ReDoS vulnerability when calling the `is_pem_format` function.

PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT ispemformat is affected because lazy PEM regular expression backtracks extensively. This occurs when a certificate-like input contains repeated BEGIN markers without a matching END marker. As a result, ispemforma...

EUVD-2026-88484

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.fromjwk is affected because PyJWK verification path used the decoded key without applying preparekey validation. This occurs when a trusted JWK Set contains an oct entry with an empty k value. As...

CVE-2026-102266 PyJWK accepts empty HMAC keys, bypassing PyJWT's empty-key validation

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.fromjwk is affected because PyJWK verification path used the decoded key without applying preparekey validation. This occurs when a trusted JWK Set contains an oct entry with an empty k value. As...

CVE-2026-101918 PyJWT: Unauthenticated RecursionError DoS in pre-verification payload parse (PyJWKClient.get_signing_key_from_jwt / verify_signature=False)

PyJWT is a Python implementation of JSON Web Token standards. From 2.0.0a1 until 2.15.0, PyJWT PyJWKClient.getsigningkeyfromjwt is affected because payload parser catches ValueError but not RecursionError. This occurs when an attacker-controlled recursively nested payload reaches json.loads. As a...

CVE-2026-101918 PyJWT: Unauthenticated RecursionError DoS in pre-verification payload parse (PyJWKClient.get_signing_key_from_jwt / verify_signature=False)

PyJWT is a Python implementation of JSON Web Token standards. From 2.0.0a1 until 2.15.0, PyJWT PyJWKClient.getsigningkeyfromjwt is affected because payload parser catches ValueError but not RecursionError. This occurs when an attacker-controlled recursively nested payload reaches json.loads. As a...

CVE-2026-101917

The PyJWT Python library (prior to version 2.14.0 ) is vulnerable to a denial-of-service vector due to how it handles unknown keys in the get_signing_key_from_jwt function. Because the library lacks a negative cache or minimum refresh interval, repeated requests using unknown or varying kid value...

EUVD-2026-88478

PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT getsigningkeyfromjwt is affected because unknown kid misses force refreshes without a negative cache or minimum refresh interval. This occurs when unauthenticated tokens repeatedly use the same unknown kid or...

CVE-2026-101861

Langflow 1.0.16 before 1.12.0 and 0.0.94 before 1.12.0 contain an unsafe eval vulnerability in schema.py that allows authenticated attackers to achieve code execution by placing a Python object with a malicious repr method into component input options lists. The eval sink is triggered when a...
