CVE-2024-42515: Pebbleroad Glossarizer

Critical severity, CVSS 9.9. EPSS: 0.5% chance of exploitation in the next 30 days.

Glossarizer through 1.5.2 improperly tries to convert text into HTML. Even though the application itself escapes special characters (e.g., <>), the underlying library converts these encoded characters into legitimate HTML, thereby possibly causing stored XSS. Attackers can append a XSS payload to a word that has a corresponding glossary entry.

Affected products

• Pebbleroad Glossarizer: up to and including 1.5.2
