CVE-2026-41131: OpenFGA has Improper Policy Enforcement

MediumCVSS 5.0 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 20/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.14% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: github.com/openfga/openfga (Go) 1.14.1.

Low priority for now. Upgrade to github.com/openfga/openfga (Go) 1.14.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
