Summary

CVE-2026-41131 is a medium-severity Use of Incorrectly-Resolved Name or Reference (CWE-706) vulnerability in Openfga Helm Charts. Its CVSS base score is 5.0 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-24 (Access Control Decisions) and AC-25 (Reference Monitor) — see the control section below for these in your framework.

Vulnerability Data

OpenFGA is an authorization/permission engine built for developers. Prior to version 1.14.1, in specific scenarios, models using conditions with caching enabled can result in two different check requests producing the same cache key. This could result in OpenFGA reusing an…

earlier cached result for a subsequent request. The preconditions for vulnerability are the model having relations which rely on condition evaluation and the user having caching enabled. OpenFGA v1.14.1 contains a fix.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 directly requires correct enforcement of authorization decisions on every access request, structurally preventing incorrect checks.

AC-24 ensures access-control decisions are made and applied consistently, reducing the chance of an incorrect authorization result.

A reference monitor that is always invoked and tamper-proof forces every authorization decision through a verified, correct path.

Information flow enforcement can constrain flows that result from an incorrectly resolved name or reference.

Least-privilege assignments shrink the set of authorizations that must be checked correctly, limiting exposure to flawed checks.

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

Secure-development practices directly prevent incorrect name/reference resolution bugs during coding.

finds

Security testing can detect incorrect name or reference resolution through fuzzing and negative test cases.

prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

degrades

Network segmentation and routing policies reduce the chance that a mis-resolved name leads to an unintended external resource.

degrades

Segregated networks limit the blast radius when a name or reference resolves outside the intended control sphere.

prevents

Secure SDLC practices include design reviews that can catch incorrect name or reference handling before deployment.
