Many web applications provide a PDF generation functionality which may contain dynamic user input. Some of these generators may be vulnerable due to HTML injection, allowing several attacks. PDF Library Enumeration Determining the PDF generation library used by a web application may be pretty easy: most of them add information in the metadata of the generated file such as the library name and version. To display the metadata of a PDF file, there are multiple options:

Here is the revised and expanded SSRF reference. Your original tools, parameter list, and Gopher POST example are preserved; the additions cover the areas that decide whether an SSRF is a reportable finding or a full cloud compromise: cloud metadata exploitation (IMDSv1/v2), DNS rebinding, redirect-based bypasses, protocol smuggling, modern localhost bypasses, and OOB confirmation for blind SSRF. Server-Side Request Forgery (SSRF) occurs when an attacker can coerce the server into making requests to an arbitrary URL. In cloud environments, a single SSRF often pivots to full account compromise via the instance metadata service (IMDS) — which is why it is consistently one of the highest-impact bug classes.
