Flame through 2.4.0 Admin Token Insufficient Session Expiration

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Flame through 2.4.0 contains an insufficient session expiration vulnerability in the login endpoint that allows attackers with former admin access to obtain tokens with arbitrary lifespans by supplying unvalidated duration parameters. Attackers can mint near-permanent administrator tokens that survive password changes, retaining full control of the dashboard since tokens are verified only against a static JWT secret that is never rotated.
