A Server-Side Request Forgery (SSRF) in JGM Pandoc v3.6.4 allows attackers to gain access to and compromise the whole infrastructure via injecting a crafted iframe. Note: Some users have stated that Pandoc by default can retrieve and parse untrusted HTML content which can enable SSRF vulnerabilities. Using the ‘--sandbox’ option or ‘pandoc-server’ can mitigate such vulnerabilities. Using pandoc with an external ‘--pdf-engine’ can also enable SSRF vulnerabilities, such as CVE-2022-35583 in wkhtmltopdf.

Pandoc versions prior to 3.1.6 contain a vulnerability that allows arbitrary file write. This occurs when processing crafted image elements in input while generating files using the --extract-media option or when outputting to PDF format. The flaw stems from an incomplete fix for a previous vulnerability (CVE-2023-35936) related to double encoded path names. Exploitation requires passing untrusted input to Pandoc with these specific options enabled, and the impact depends on the privileges of the Pandoc process.
