CVE-2026-16766
CriticalCVSS 9.8Exploitation Probability (EPSS)
Elevated risk68th percentile - higher than 68% of all known CVEs
Summary
In Catalyst::View::Wkhtmltopdf for Perl versions before 0.6.1, shell command injection (RCE) is possible via PDF render options. Options are passed directly to the wkhtmltopdf command without sanitization, allowing arbitrary command execution.
Risk Assessment
The risk includes remote code execution (RCE) by an attacker controlling options like page_size, orientation, or margins, potentially leading to full server compromise.
Recommendation
Upgrade immediately to version 0.6.1 or later. Since wkhtmltopdf is no longer maintained, consider migrating to alternative solutions.
Original NVD description (English source)
Catalyst::View::Wkhtmltopdf versions before 0.6.1 for Perl allow shell command injection (RCE) via PDF render options. Options are passed directly to the wkhtmltopdf command without sanitization. Any web application that passes user-controlled options such as the page_size, orientation or margins without validation allows shell command injection. Version 0.6.0 was released with an incomplete fix for this issue. Note that the wkhtmltopdf project is no longer being developed, and users of this package should migrate to alternative solutions.
