Doc Text:
A flaw was found in xhtml2pdf. This vulnerability allows an attacker to execute arbitrary commands by convincing a user to process a file with a specially crafted name while using the viewer option. Because the software fails to properly sanitize the file name before passing it to the operating system, the injected commands run with the permissions of the user executing the tool.

Description OSIDB Bzimport 2026-10-14 14:32:27 UTC
xhtml2pdf before 0.2.19 contains an OS command injection vulnerability in pisa.startViewer() that allows attackers to execute commands by interpolating unescaped file names into os.system. Attackers can supply an input file whose name contains a double quote and shell metacharacters, which runs OS commands as the invoking user when the pisa tool is used with -s/--start-viewer.
