OpenFGA: Cache-key delimiter injection in openfga/openfga shared-iterator and v2 iterator caches enables intra-store authorization-decision poisoning

Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

cve-program · CVE-2026-48096

Published

OpenFGA is an authorization/permission engine built for developers. Prior to version 1.16.0, when iterator caching is enabled, two distinct check requests can produce the same cache key, leading to OpenFGA reusing an earlier cached result for a subsequent request. This issue has been patched in version 1.16.0.
