CVE-2026-87973: Unknown If-So Dynamic Content

Low severity, CVSS 3.1. EPSS: 0.1% chance of exploitation in the next 30 days.

The If-So Dynamic Content WordPress plugin before 1.10.2 does not sanitize a conversion name before storing it, nor escape it when rendering the analytics page, allowing users with editor-level access to store JavaScript that executes in the session of a higher-privileged user who views that page.

Affected products

• Unknown If-So Dynamic Content: from 1.9.9, before 1.10.2 (fixed in 1.10.2)
