CVE-2026-29000-pac4j-jwt

pac4j-jwe-forge CVE-2026-29000 Proof-of-concept for CVE-2026-29000. Targets pac4j-jwt versions prior to 4.5.9, 5.7.9, and 6.3.3. The vulnerability is straightforward: the library accepts a PlainJWT unsigned, alg=none as long as it's wrapped inside a valid JWE. Since the server exposes its RSA...

CVE-2026-116587 Go JOSE: DoS when parsing JWKs that contain RSA keys

Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption JWE, JSON Web Signature JWS, and JSON Web Token JWT standards. Prior to 4.1.6, go-jose parses attacker-controlled RSA modulus and prime values from...

CVE-2026-116587

The go-jose library (prior to version 4.1.6 ) is vulnerable to a Remote Denial of Service (DoS) due to inefficient algorithmic complexity. When parsing JSON Web Keys (JWKs) from untrusted sources, the library fails to enforce size and consistency bounds on RSA modulus and prime values before pass...

CVE-2026-89314

jwkFields.CheckConsistency detected duplicate keyops entries with a pairwise nested loop, making validation cost grow with the square of the entry count. Because the check runs on every JWK and JWKS unmarshal, a modestly sized but hostile JWKS document could occupy a CPU core for many seconds...

CVE-2026-89313

JwksTrustStore.Get assigned each parsed key to the function's named return value while refreshing the JWKS cache. When the requested kid was not present, the trailing naked return handed the caller the last key in the JWKS document together with a nil error — a confidently wrong answer instead of...

jwkFields.CheckConsistency detected duplicate keyops entries with a pairwise nested loop, making validation cost grow with the square of the entry count. Because the check runs on every JWK and JWKS unmarshal, a modestly sized but hostile JWKS document could occupy a CPU core for many seconds...

CVE-2026-89314

The jwkFields.CheckConsistency function is vulnerable to a quadratic-time complexity issue during the duplicate check of key_ops entries. Because the validation uses a pairwise nested loop, the processing cost grows with the square of the entry count. An attacker can provide a modestly sized (sub...

CVE-2026-89314 Quadratic-time key_ops duplicate check lets a sub-1 MB JWKS body pin a CPU core for ~15 s

jwkFields.CheckConsistency detected duplicate keyops entries with a pairwise nested loop, making validation cost grow with the square of the entry count. Because the check runs on every JWK and JWKS unmarshal, a modestly sized but hostile JWKS document could occupy a CPU core for many seconds...

CVE-2026-89313 JwksTrustStore.Get returns the last fetched JWKS key (err=nil) when the requested kid is absent, instead of nil

JwksTrustStore.Get assigned each parsed key to the function's named return value while refreshing the JWKS cache. When the requested kid was not present, the trailing naked return handed the caller the last key in the JWKS document together with a nil error — a confidently wrong answer instead of...

CVE-2026-89313

The JwksTrustStore.Get function in the gose library is vulnerable to a logic error where it returns the last fetched JWKS key with a nil error when a requested kid is absent. This occurs because the function assigns parsed keys to a named return value during cache refreshes, and a trailing naked ...

pyjwt: pyjwt: Verification key substitution via unvalidated JWKS redirects

A flaw was found in PyJWT. When retrieving cryptographic keys from a JSON Web Key Set JWKS endpoint, PyJWKClient fails to validate HTTP redirect destinations against trusted domain boundaries. A remote attacker who can influence the response of a trusted endpoint can redirect key requests to an...

CVE-2026-108062

The CVE-2026-108062 vulnerability involves pre-authentication OIDC discovery and JWKS fetches running synchronously on the asyncio event loop . This synchronous execution causes a single unauthenticated request to stall the entire service, leading to a CWE-400 Uncontrolled Resource Consumption is...

CVE-2026-67409

A flaw was found in rabbitmq-server. When retrieving cryptographic signing keys from an identity provider's JSON Web Key Set JWKS endpoint, the server fails to validate HTTP response status codes. If an error response is returned with valid JSON lacking key data, all previously cached signing key...
