Weglot < 6.4.3 - Unauthenticated Stored XSS via Translated Page Link Rewriting

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 Translate WordPress with Weglot 2.0 WordPress plugin before 6.4.3 does not escape the URLs it re-inserts into a page when rewriting links for a translated language, and reverses the encoding that was applied to them beforehand, allowing unauthenticated users to store a payload which executes in the browser of anyone viewing the page in a translated language.
