cve-program · CVE-2026-96460

Published

A flaw was found in the token exchange mechanism of Keycloak. When using Standard Token Exchange V2, the system issues new tokens with a fresh lifetime based on the requester clients configuration instead of limiting it to the original tokens expiration. This issue allows an authenticated requester to indefinitely extend access for service accounts by repeatedly exchanging tokens, even if the original client has been disabled by an administrator.

Affected versions, risk and source history

Exploitation and risk

Source status

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.

Risk history

Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.

When does an EPSS score appear as a change?

A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.

See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.

How advisory history works

Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
