GHSA-M93H-GJV2-FMQ2
Vulnerability from github – Published: 2026-06-12 18:32 – Updated: 2026-06-29 21:31SimpleHelp versions 5.5.15 and prior and 6.0 pre-release versions contain an authentication bypass vulnerability in the OIDC authentication flow. When OIDC authentication is configured, identity tokens submitted during login are accepted without verifying their cryptographic signature. In a vulnerable configuration, a remote, unauthenticated attacker can submit a forged token containing arbitrary identity claims to obtain a fully authenticated technician session. In some configurations, this may also allow bypass of multi-factor authentication. No user interaction is required.

GHSA-M95P-425X-X889
Vulnerability from github – Published: 2025-11-25 20:41 – Updated: 2025-11-27 08:59Impact
cggmp21 concerns a missing check in the ZK proof that enables an attack in which a single malicious signer can reconstruct full private key.
Patches
cggmp21 v0.6.3is a patch release that contains a fix that introduces this specific missing check- However, cggmp21 recommends upgrading to
cggmp24 v0.7.0-alpha.2which contains many other security checks as a precaution. Follow migration guideline to upgrade.
Workarounds
Update to cggmp21 v0.6.3, a minor release that contains a minimal security patch.
However, for full mitigation, users will need to upgrade to cggmp24 v0.7.0-alpha.2 as it contains many more security check implementations.

GHSA-M974-647V-WHV7
Vulnerability from github – Published: 2022-10-12 22:05 – Updated: 2022-10-18 03:11Impact
A remote attacker may be able to bypass SAML authentication on a website using passport-saml. A successful attack requires that the attacker is in possession of an arbitrary IDP signed XML element. Depending on the IDP used, fully unauthenticated attacks (e.g without access to a valid user) might also be feasible if generation of a signed message can be triggered.
Patches
Users should upgrade to passport-saml 3.2.2 or newer. The issue was also present in the beta releases of node-saml before v4.0.0-beta.5.
Workarounds
Disable SAML authentication.

GHSA-MCGX-2GCR-P3HP
Vulnerability from github – Published: 2025-02-25 17:48 – Updated: 2026-06-05 17:54Impact
Only users that has configured a JupyterHub installation to use the authenticator class LTI13Authenticator are influenced.
LTI13Authenticator that was introduced in jupyterhub-ltiauthenticator 1.3.0 wasn't validating JWT signatures. This is believed to allow the LTI13Authenticator to authorize a forged request granting access to existing and new user identities.
Patches
None.
Workarounds
None.
References
- This code segment didn't validate a JWT signature.

CAPEC-463: Padding Oracle Crypto Attack
An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
