• build: bump go to 1.24.2 (#​7544) (authored by @​sspaink)
  Addressing CVE-2025-22870 and CVE-2025-22871 vulnerabilities in the Go runtime.

v1.4.0

Compare Source

This release contains a security fix addressing CVE-2025-46569.
It also includes a mix of new features, bugfixes, and dependency updates.

Security Fix: CVE-2025-46569 - OPA server Data API HTTP path injection of Rego (GHSA-6m8w-jc87-6cr7)

A vulnerability in the OPA server's Data API allows an attacker to craft the HTTP path in a way that injects Rego code into the query that is evaluated.
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.

Users are only impacted if all of the following apply:

• OPA is deployed as a standalone server (rather than being used as a Go library)
• The OPA server is exposed outside of the local host in an untrusted environment.
• The configured authorization policy does not do exact matching of the input.path attribute when deciding if the request should be allowed.

or, if all of the following apply:

• OPA is deployed as a standalone server.
• The service connecting to OPA allows 3rd parties to insert unsanitised text into the path of the HTTP request to OPA’s Data API.

Note: With no Authorization Policy configured for restricting API access (the default configuration), the RESTful Data API provides access for managing Rego policies; and the RESTful Query API facilitates advanced queries.
Full access to these APIs provides both simpler, and broader access than what the security issue describes here can facilitate.
As such, OPA servers exposed to a network are not considered affected by the attack described here if they are knowingly not restricting access through an Authorization Policy.

This issue affects all versions of OPA prior to 1.4.0.

See the Security Advisory for more details.
