CVE-2025-68476

Description

A flaw was found in KEDA, a Kubernetes-based Event Driven Autoscaling component. This arbitrary file read vulnerability allows an attacker with permissions to create or modify a TriggerAuthentication resource to read any file from the node's filesystem where the KEDA pod resides. This is due to insufficient path validation when handling Service Account Tokens during HashiCorp Vault authentication. Successful exploitation can lead to the exfiltration of sensitive system information, such as secrets or configuration files.

Statement

This vulnerability is rated Important because an attacker with permissions to create or modify a KEDA TriggerAuthentication resource can perform arbitrary file reads from the node's filesystem. This impacts Red Hat OpenShift products that utilize KEDA with HashiCorp Vault authentication.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Integrity,Confidentiality,Availability

Technical Impact: Execute Unauthorized Code or Commands

The attacker may be able to create or overwrite critical files that are used to execute code, such as programs or libraries.

Integrity

Technical Impact: Modify Files or Directories

The attacker may be able to overwrite or create critical files, such as programs, libraries, or important data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, appending a new account at the end of a password file may allow an attacker to bypass authentication.

Confidentiality

Technical Impact: Read Files or Directories

The attacker may be able read the contents of unexpected files and expose sensitive data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, by reading a password file, the attacker could conduct brute force password guessing attacks in order to break into an account on the system.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

The attacker may be able to overwrite, delete, or corrupt unexpected critical files such as programs, libraries, or important data. This may prevent the product from working at all and in the case of protection mechanisms such as authentication, it has the potential to lock out product users.
