CVE-2024-10891: Pdfcrowd Save As PDF

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The Save as PDF Plugin by Pdfcrowd plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'save_as_pdf_pdfcrowd' shortcode in all versions up to, and including, 4.2.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• Pdfcrowd Save As PDF: before 4.2.2 (fixed in 4.2.2)
