jose-swift has JWT Signature Verification Bypass via None Algorithm

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 complete...

The vulnerability of the LTI13Authenticator function of the JupyterHub jupyterhub-ltiauthenticator, related to cryptographic signature verification errors, allows a perpetrator to execute remote code, thereby enabling them to influence the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the LTI13Authenticator function of the JupyterHub jupyterhub-ltiauthenticator component is related to errors in verifying the cryptographic signature. Exploiting this vulnerability could allow an attacker to influence the confidentiality, integrity, and accessibility of the...

User Impersonation

Overview n8n-nodes-base is a Base nodes of n8n Affected versions of this package are vulnerable to User Impersonation via the Stripe Trigger node that does not verify incoming webhook requests against Stripe webhook signing secret. An attacker with valid webhook URL can execute unauthorized...

n8n's Missing Stripe-Signature Verification Allows Unauthenticated Forged Webhooks

Impact An authentication bypass in the Stripe Trigger node allows unauthenticated parties to trigger workflows by sending forged Stripe webhook events. The Stripe Trigger creates and stores a Stripe webhook signing secret when registering the webhook endpoint, but incoming webhook requests were n...
