LightRAG data falsification vulnerability
LightRAG is an open-source retrieval-enhanced generation application developed by the Data Intelligence Laboratory at the Hong Kong University HKU. Versions of LightRAG prior to 1.4.14 contained a data manipulation vulnerability caused by JWT algorithm exploitation attacks. This vulnerability...
CVE-2026-39413: Improper Verification of Cryptographic Signature
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'...

SUSE CVE-2026-28802
Authlib is a Python library which builds OAuth and OpenID Connect servers. From version 1.6.5 to before version 1.6.7, previous tests involving passing a malicious JWT containing alg: none and an empty signature was passing the signature verification step without any changes to the application co...

Name of the Vulnerable Software and Affected Versions Authlib versions 1.6.5 through 1.6.7 Description Authlib, a Python library for building OAuth and OpenID Connect servers, had a flaw in signature verification. Specifically, tests involving a malicious JWT with 'alg: none' and an empty signatu...
CVE-2026-27804
Parse Server versions prior to 8.6.3 and 9.1.1-alpha.4 are vulnerable to unauthenticated login via forged Google tokens (alg: none). The root cause is trusting the JWT header for algorithm selection; the fix hardcodes RS256 and shifts key validation to jwks-rsa, rejecting unknown key IDs. Affecte...
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-2025-61152
The python-jose library (through version 3.3.0 ) allows JWT tokens using 'alg=none' to be decoded and accepted without cryptographic signature verification. This allows an attacker to craft forged tokens with arbitrary claims to bypass authentication, potentially leading to privilege escalation o...
CVE-2025-61152
python-jose thru 3.3.0 allows JWT tokens with 'alg=none' to be decoded and accepted without any cryptographic signature verification. A malicious actor can craft a forged token with arbitrary claims e.g., isadmin=true and bypass authentication checks, leading to privilege escalation or unauthoriz...
