A Local File Inclusion (LFI) and a Server-Side Request Forgery (SSRF) vulnerability was found in the InsertFromHtmlString() function of the Apryse HTML2PDF SDK thru 11.6.0. These vulnerabilities could allow an attacker to read local files on the server or make arbitrary HTTP requests to internal or external services. Both vulnerabilities could lead to the disclosure of sensitive data or potential system takeover.
