CVE-2025-46569— Open Policy Agent 安全漏洞

OPA server Data API HTTP path injection of Rego

Open Policy Agent (OPA) is an open source, general-purpose policy engine. Prior to version 1.4.0, when run as a server, OPA exposes an HTTP Data API for reading and writing documents. Requesting a virtual document through the Data API entails policy evaluation, where a Rego query containing a single data document reference is constructed from the requested path. This query is then used for policy evaluation. A HTTP request path can be crafted in a way that injects Rego code into the constructed query. The evaluation result cannot be made to return any other data than what is generated by the requested path, but this path can be misdirected, and the injected Rego code can be crafted to make the query succeed or fail; opening up for oracle attacks or, given the right circumstances, erroneous policy decision results. Furthermore, the injected code can be crafted to be computationally expensive, resulting in a Denial Of Service (DoS) attack. This issue has been patched in version 1.4.0. A workaround involves having network access to OPA’s RESTful APIs being limited to `localhost` and/or trusted networks, unless necessary for production reasons.

Open Policy Agent 安全漏洞

Open Policy Agent（OPA）是Open Policy Agent开源的一个开源的通用策略引擎，可在整个堆栈中实现统一的、上下文感知的策略实施。 Open Policy Agent 1.4.0之前版本存在安全漏洞，该漏洞源于HTTP Data API允许注入Rego代码，可能导致拒绝服务攻击或错误策略决策。
