Deeper analysis
wkhtmltopdf 0.12.6 contains a server-side request forgery vulnerability tracked as CVE-2022-35583 and assigned CWE-918. The flaw arises when the tool processes HTML containing an iframe tag whose source attribute references an internal IP address, allowing the application to issue requests to assets that should remain inaccessible from outside the target environment. The issue carries a CVSS 3.1 score of 9.8.
An unauthenticated remote attacker can exploit the weakness by supplying a crafted HTML document to wkhtmltopdf. Successful exploitation grants the attacker initial network access to internal systems and the ability to interact with further assets, potentially leading to full infrastructure compromise.
The EPSS score for the CVE currently stands at 0.5860 with a recorded peak of 0.5942.
