Summary
The PrePost SEO WordPress plugin through 3.0 does not properly sanitize some of its settings, which could allow high-privilege users to perform Stored Cross-Site Scripting (XSS) attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)
Exploit prediction
0.63% chance of exploitation in the next 30 days, higher than 50% of all scored CVEs (FIRST EPSS, 2026-11-08).
