CVE-2026-41580: Stirling PDF

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. Prior to 2.0.0, Stirling-PDF's /get-info-on-pdf endpoint rendered PDF Title and Author metadata fields without proper HTML encoding or sanitization, allowing a crafted PDF to execute attacker-controlled JavaScript in the browser of a user who views the resulting page. This issue is fixed in version 2.0.0.

Affected products

• Stirling Stirling PDF: before 2.0.0 (fixed in 2.0.0)
