CVE-2025-46569
Description
A flaw was found in Open Policy Agent (OPA) that could lead to information disclosure and a denial of service. An attacker can inject malicious Rego code by sending specially crafted HTTP requests to the Data API. This injected code can then be leveraged to conduct Oracle attacks, potentially revealing sensitive information and impacting system availability.
Statement
This vulnerability is rated as an IMPORTANT severity because this flaw allows an attacker to craft a malicious HTTP request path that injects Rego code into the constructed policy query, allowing an attacker to determine query success or failure, and under certain circumstances, produce erroneous policy decision result, injected code can result in a Denial of Service (DoS) attack, impacting the availability of the OPA server.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
