HAXcms: Mass Token Exfiltration and Cross-Tenant Hijack

Summary An attack chain utilizing Stored XSS alongside dynamic token exposure in the /system/api/connectionSettings endpoint allows an authenticated attacker to perform a complete cross-tenant account takeover. The API dynamically leaks the active session's authentication tokens including the jwt...

HAXcms: Private Key Disclosure via Broken HMAC Implementation

Summary The hmacBase64 function in the HAXcms Node.js backend contains two critical cryptographic implementation errors that together allow any unauthenticated attacker to extract the system’s private signing key and forge arbitrary admin-level JSON Web Tokens JWTs allowing them to get full admin...

GHSA-C32J-VQHX-RX3X ruby-jwt: Empty-key HMAC bypass; cross-language sibling of CVE-2026-44351

JWT.decodetoken, '', true, algorithm: 'HS256' accepts an attacker-forged token. OpenSSL::HMAC.digest'SHA256', '', payload returns a valid digest under an empty key, and no raise InvalidKeyError if key.empty? precondition exists in the HMAC algorithm. JWT.decodetoken, "", true, algorithm: 'HS256' ...

Improper Authentication

Overview Affected versions of this package are vulnerable to Improper Authentication in the signing and verification logic before applying JWT.decode. An attacker can forge valid JWTs by supplying a crafted token that passes signature verification due to the acceptance of empty keys. Note: This i...

CVE-2026-44699

A flaw was found in libjwt. This vulnerability allows a remote attacker to bypass authentication by forging a valid JSON Web Token JWT. The flaw occurs because libjwt accepts an RSA JSON Web Key JWK that does not contain an 'alg' parameter as the verification key for HMAC-based tokens. This leads...

CVE-2021-47942

Home Assistant Community Store HACS prior to 1.10.0 contains a path traversal vulnerability that allows unauthenticated attackers to read sensitive files by traversing directories via the /hacsfiles/ endpoint. Attackers can retrieve the .storage/auth file containing user credentials and refresh...

Origin Validation Error

Dozzle is vulnerable to Origin Validation Error. The vulnerability is due to improper origin validation in the WebSocket upgrader, where connections from any origin are accepted and authenticated with the victim's JWT cookie, allowing attackers to hijack authenticated sessions and gain unauthoriz...

Use Of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

Cloudreve is vulnerable to Use of Cryptographically Weak Pseudo-Random Number Generator PRNG. The vulnerability is due to the generation of security-sensitive secrets using math/rand seeded with predictable timestamps, which allows an attacker to recover the secret key, forge JWTs, and gain...

Server-Side Request Forgery (SSRF)

github.com/centrifugal/centrifug is vulnerable to Server-Side Request Forgery SSRF. The vulnerability is due to improper handling of dynamic JWKS endpoint template variables, which allows an unauthenticated attacker to craft a malicious JWT with manipulated iss or aud claims to force Centrifugo t...

Sensitive Information Exposure

Portainer Community Edition is vulnerable to Exposure of Sensitive Information. The vulnerability is due to the authentication middleware accepting JWT bearer tokens through the ?token= URL query parameter, which allows an attacker to obtain authentication tokens from browser history, proxy logs,...

EUVD-2026-30560

LibJWT is a C JSON Web Token Library. From 3.0.0 to 3.3.2, libjwt accepts an RSA JWK that does not contain an alg parameter as the verification key for an HS256/HS384/HS512 token. In the OpenSSL backend, this causes HMAC verification to run with a zero-length key, so an attacker can forge a valid...

Improper Authentication

github.com/openbao/openbao is vulnerable to improper authentication. The vulnerability is due to missing user confirmation during JWT/OIDC authentication when using callbackmode=direct, which allows an attacker to initiate a malicious authentication request and trick a victim into automatically...

Inadequate Encryption Strength

Overview Affected versions of this package are vulnerable to Inadequate Encryption Strength due to insufficient enforcement of length and entropy requirements for the JWTSECRET configuration value. An attacker can gain unauthorized access to user accounts by forging authentication tokens using we...

User Impersonation

Overview Affected versions of this package are vulnerable to User Impersonation due to improper validation of JWT aud and iss claims in the Windows MDM authentication flow. An attacker can enroll unauthorized devices by presenting a valid Microsoft-signed Azure AD token from any tenant. This is...
