CVE-2019-25146Known exploitationPublic exploitNetwork attack vector

Stored script execution via unchecked settings save

Published Jun 7, 2023 · Updated Apr 8, 2026

Stored cross-site scripting in DELUCKS SEO 2.1.7 and earlier allows remote attackers to inject scripts through unauthenticated settings requests. The saveSettings() function accepts unsanitized settings without a capability check and stores them in the dpc_basic_metadata option for unescaped output on site pages. No account is required; the stored script runs in a visitor's browser whenever an affected page loads, enabling page-content modification and data access in that browser context.
