Description
A SMB force-authentication vulnerability exists in all versions of OPA for Windows prior to v0.68.0. The vulnerability exists because of improper input validation, allowing a user to pass an arbitrary SMB share instead of a Rego file as an argument to OPA CLI or to one of the OPA Go library’s functions.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/open-policy-agent/opa, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/open-policy-agent/opa to 0.68.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-8260 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
The SMB force-authentication vulnerability in OPA for Windows builds is classified as moderate severity due to its specific exploitation requirements and potential impact. The flaw arises from improper input validation, allowing an attacker to supply an arbitrary SMB share instead of a Rego file. However, exploitation…
