CVE-2025-53276Network attack vector

Stored script execution via unsanitized SVG content

Published Jun 27, 2025 · Updated May 13, 2026

Stored cross-site scripting in Omnipress 1.6.4 and earlier allows remote authenticated users to execute scripts in visitors' browsers. The plugin accepts attacker-controlled SVG page content without sufficient input sanitization and later renders it without safe output escaping. Contributor-level access is sufficient, and execution occurs when another user visits the affected WordPress page.
