CVE-2026-85618 Details
Description
ConvertX 0.17.0 contains an arbitrary file read vulnerability in the xelatex converter that allows authenticated users to read files by uploading LaTeX files with input directives. Attackers can upload .tex files containing \\input{path} or \\verbatiminput{path} directives to have the TeX engine read arbitrary files accessible to the server process and include them in downloadable PDF output.
A vulnerability allowing arbitrary file read has been identified in ConvertX version 0.17.0, specifically within the XeLaTeX converter. This issue arises from the converter's handling of LaTeX files, which can be exploited by authenticated users. Attackers can upload .tex files that include \input or \verbatiminput directives, prompting the TeX engine to read and include the contents of arbitrary files accessible to the server process into the generated PDF. The vulnerability takes advantage of the fact that the XeLaTeX converter executes without inspecting or restricting the file content, allowing sensitive files to be exfiltrated through the PDF output.
