CVE-2026-82454 Omnivore before android-0.227.0 Authentication Bypass via Apple Sign-in

The Omnivore API packages/api before the fix in commit abf53d6 contains an authentication bypass in Apple sign-in token verification. The decodeAppleToken function extracted the 'alg' field from the attacker-supplied JWT header and passed it as the sole allowed algorithm to jwt.verify. Using...

Name of the Vulnerable Software and Affected Versions Omnivore API packages/api versions prior to commit abf53d6 Description An authentication bypass exists in the Apple sign-in token verification process. The decodeAppleToken function extracts the alg field from the JWT header provided by the us...

BIT-KEYCLOAK-2026-11800 Org.keycloak:keycloak-services: keycloak: authentication bypass via jwt algorithm confusion

A flaw was found in Keycloak. This JWT algorithm confusion vulnerability in the JWT Authorization Grant flow allows an attacker with valid client credentials to bypass signature verification. By forging an assertion, the attacker can create unauthorized access tokens. This enables the attacker to...

CVE-2026-55165 Lemur : JWT verifier trusts attacker-supplied alg from token header — defense-in-depth gap; chain-dependent ATO with secret disclosure

Lemur manages TLS certificate creation. Prior to 1.9.2, the JWT verifier in lemur/auth/service.py:130-137 used fetchtokenheader to read headerdata"alg" from an unverified token and passed that attacker-controlled value to decodewithmultiplesecrets. PyJWT 2.x rejects alg=none with the configured...

CVE-2026-11800: Improper Verification of Cryptographic Signature

A flaw was found in Keycloak. This JWT algorithm confusion vulnerability in the JWT Authorization Grant flow allows an attacker with valid client credentials to bypass signature verification. By forging an assertion, the attacker can create unauthorized access tokens. This enables the attacker to...

CVE-2026-39999 Apache APISIX: JWT Algorithm Confusion allows authentication bypass

Authentication Bypass by Spoofing vulnerability in Apache APISIX. The attacker can completely bypass authentication capitalising on certain configurations of jwt-auth plugin. This issue affects Apache APISIX: from v2.2 through v3.16.0. Users are recommended to upgrade to version v3.17.0, which...

CVE-2026-39413 LightRAG has a JWT Algorithm Confusion Vulnerability in LightRAG API

LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.4.14, the LightRAG API is vulnerable to a JWT algorithm confusion attack where an attacker can forge tokens by specifying 'alg': 'none' in the JWT header. Since the jwt.decode call does not explicitly deny the 'none'...

CVE-2026-34950 fast-jwt has an incomplete fix for CVE-2023-48223: JWT Algorithm Confusion via Whitespace-Prefixed RSA Public Key

fast-jwt provides fast JSON Web Token JWT implementation. In 6.1.0 and earlier, the publicKeyPemMatcher regex in fast-jwt/src/crypto.js uses a ^ anchor that is defeated by any leading whitespace in the key string, re-enabling the exact same JWT algorithm confusion attack that CVE-2023-48223 patch...

CVE-2026-34950: Use of a Broken or Risky Cryptographic Algorithm

fast-jwt provides fast JSON Web Token JWT implementation.

CVE-2026-33322: Improper Authentication

MinIO is a high-performance object storage system. From RELEASE.2022-11-08T05-27-07Z to before RELEASE.2026-03-17T21-25-16Z, a JWT algorithm confusion vulnerability in MinIO's OpenID Connect authentication allows an attacker who knows the OIDC ClientSecret to forge arbitrary identity tokens and...

Parse Server: Account takeover via JWT algorithm confusion in Google auth adapter

Impact An unauthenticated attacker can forge a Google authentication token with alg: "none" to log in as any user linked to a Google account, without knowing their credentials. All deployments with Google authentication enabled are affected. Patches The fix hardcodes the expected RS256 algorithm...

CVE-2026-22817 JWT Algorithm Confusion via Unsafe Default (HS256) in Hono JWT Middleware Allows Token Forgery and Auth Bypass

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.11.4, there is a flaw in Hono’s JWK/JWKS JWT verification middleware allowed the JWT header’s alg value to influence signature verification when the selected JWK did not explicitly specify an algorith...

CVE-2025-68925 Jervis has a JWT Algorithm Confusion Vulnerability

Jervis is a library for Job DSL plugin scripts and shared Jenkins pipeline libraries. Prior to 2.2, the code doesn't validate that the JWT header specifies "alg":"RS256". This vulnerability is fixed in 2.2...

CVE-2023-48223 fast-jwt JWT Algorithm Confusion

fast-jwt provides fast JSON Web Token JWT implementation. Prior to version 3.3.2, the fast-jwt library does not properly prevent JWT algorithm confusion for all public key types. The 'publicKeyPemMatcher' in 'fast-jwt/src/crypto.js' does not properly match all common PEM formats for public keys. ...
