Hono JWT Middleware's JWT Algorithm Confusion via Unsafe Default (HS256) Allows Token Forgery and Auth Bypass
Summary 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 algorithm. This could enable JWT algorithm confusion and, in certain configurations, allow forged tokens to be...

GHSA-88Q6-JCJG-HVMW jose-swift has JWT Signature Verification Bypass via None Algorithm
Summary An authentication bypass vulnerability allows any unauthenticated attacker to forge arbitrary JWT tokens by setting "alg": "none" in the token header. The library's verification functions immediately return true for such tokens without performing any cryptographic verification, enabling...
CVE-2023-25403
CleverStupidDog yf-exam v 1.8.0 is vulnerable to Authentication Bypass. The program uses a fixed JWT key, and the stored key uses username format characters. Any user who logged in within 24 hours. A token can be forged with his username to bypass authentication...
CVE-2022-31053
Biscuit is an authentication and authorization token for microservices architectures. The Biscuit specification version 1 contains a vulnerable algorithm that allows malicious actors to forge valid Γ-signatures. Such an attack would allow an attacker to create a token with any access level. The...

CVE-2020-36913 All-Dynamics Software enlogic:show 2.0.2 Session Fixation Authentication Bypass
All-Dynamics Software enlogic:show 2.0.2 contains a session fixation vulnerability that allows attackers to set a predefined PHP session identifier during the login process. Attackers can forge HTTP GET requests to welcome.php with a manipulated session token to bypass authentication and...
CVE-2025-11723
The Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.6.9.5 via the hash function due to use of a hardcoded fall-back salt. This makes it possible for...
Improper Cryptographic Key Management
Apache StreamPark is vulnerable to Improper Cryptographic Key Management. The vulnerability is due to using the user’s password directly as the HMAC signing key for JWTs, which allows an attacker to brute-force passwords offline or forge valid tokens to impersonate users and take over accounts...
Use Of Hard-coded Cryptographic Key
AstrBot is vulnerable to the Use of Hard-coded Cryptographic Key. The vulnerability is due to the presence of a hard-coded signing key in the application, which allows an attacker to forge tokens and execute arbitrary commands by installing a malicious plugin...
CVE-2025-53960
When issuing JSON Web Tokens JWT, Apache StreamPark directly uses the user's password as the HMAC signing key e.g., with the HS256 algorithm. An attacker can exploit this vulnerability to perform offline brute-force attacks on the user's password using a captured JWT, or to arbitrarily forge...
