Five Star Business Profile and Schema 2.3.20 - 2.3.21 - Author+ Sensitive Data Disclosure via Schema Field Default Callback

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.

The Five Star Business Profile and Schema WordPress plugin before 2.4.0 does not properly restrict the callbacks used to resolve schema field default values, allowing authenticated users with Author-level access and above to store input that discloses sensitive data, including other users' password hashes and arbitrary site option values, in public output readable by unauthenticated visitors.
