CVE-2026-22183
wpDiscuz before 7.6.47 contains a stored cross-site scripting vulnerability in the inline comment preview functionality that allows authenticated users to inject malicious scripts by submitting comments with unescaped content.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description
