high Tenable Cloud Security Plugin ID 434719

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2025-46569)
