Welcart e-Commerce < 2.12.6 - Unauthenticated Open Redirect via 'usces_referer' Parameter

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 Welcart e-Commerce WordPress plugin before 2.12.6 does not validate a user-supplied URL before using it in a redirect, allowing unauthenticated attackers to redirect users to arbitrary external websites.
