pappl-retrofit directory traversal in PPD actions (CVE-2026-123747)
The flaw affects add-ppdfiles and delete-ppdfiles, with a fix planned for a release soon after the advisory.
Directory traversal in pappl-retrofit PPD upload and delete
pappl-retrofit does not sanitize user-supplied filenames when adding or deleting PostScript Printer Description (PPD) files. A remote attacker can submit path-traversal sequences to upload or delete arbitrary files on the system. That can corrupt data, cause denial of service, or lead to arbitrary command execution. Affected versions are not listed.
What to do: No fixed version is listed. Apply the maintainer update that addresses CVE-2026-123747.
