Answer in brief
CVE-2026-16766 records a Unknown severity vulnerability in Catalyst::View::Wkhtmltopdf versions before 0.6.1 for Perl allow shell command injection (RCE) via PDF render options. The current sources do not mark it as known exploited. The current feed maps RRWO/Catalyst::View::Wkhtmltopdf (generic). Check affected ranges and fixed versions before updating.

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.
