CVE-2026-54431

A flaw was found in liboauth2. The Demonstrating Proof-of-Possession DPoP verifier incorrectly accepts a malformed DPoP proof. This proof contains private key material in its JSON Web Key JWK header, which should be rejected according to RFC 9449. This vulnerability could allow an attacker to...

CVE-2026-59096

Dapr Sentry’s OIDC discovery endpoint can be poisoned: the issuer and jwks_uri in /.well-known/openid-configuration are derived from the request Host via an attacker-controlled X-Forwarded-Host when oidc-allowed-hosts is not configured, and the document is cached for one hour. This allows remote ...

CVE-2026-59096 Dapr - OIDC Discovery Issuer and JWKS URI Injection via Unvalidated X-Forwarded-Host

Dapr Sentry's OIDC discovery endpoint derives the issuer and jwksuri of the /.well-known/openid-configuration document from the request Host, honoring an attacker-controlled X-Forwarded-Host header without validation when no allowed-hosts list is configured the default, and serves the document wi...

UBUNTU-CVE-2026-54431

In liboauth2 the Demonstrating Proof-of-Possession DPoP verifier accepts a proof whose JSON Web Key jwk header contains private key material. RFC 9449 section 4.3 step 7 requires the verifier to reject such a proof but oauth2tokenverify function returns success for a malformed DPoP proof that...

CVE-2026-54431

CVE-2026-54431 affects the liboauth2 DPoP verifier. The bug allows a DPoP proof whose JWK header embeds private key material to be accepted, violating RFC 9449 section 4.3 step 7, because the function oauth2_token_verify() returns success for a malformed DPoP proof that embeds the private EC key ...

EUVD-2026-41277

In liboauth2 the Demonstrating Proof-of-Possession DPoP verifier accepts a proof whose JSON Web Key jwk header contains private key material. RFC 9449 section 4.3 step 7 requires the verifier to reject such a proof but oauth2tokenverify function returns success for a malformed DPoP proof that...

CVE-2026-54431 Improper Data Validation in liboauth2

In liboauth2 the Demonstrating Proof-of-Possession DPoP verifier accepts a proof whose JSON Web Key jwk header contains private key material. RFC 9449 section 4.3 step 7 requires the verifier to reject such a proof but oauth2tokenverify function returns success for a malformed DPoP proof that...

python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens

A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

PYSEC-2026-287 Authlib JWS JWK Header Injection: Signature Verification Bypass

Description Summary A JWK Header Injection vulnerability in authlib's JWS implementation allows an unauthenticated attacker to forge arbitrary JWT tokens that pass signature verification. When key=None is passed to any JWS deserialization function, the library extracts and uses the cryptographic...
