AI-suggested

European organizations should immediately upgrade all instances of ConvertX to version 0.17.0 or later, where the vulnerability is patched. Until upgrades can be applied, organizations should implement strict network segmentation and firewall rules to limit access to the ConvertX service to trusted internal users only. Employ application-layer filtering or web application firewalls (WAFs) to detect and block requests containing path traversal sequences in the filename parameter. Review and harden file system permissions for the ConvertX server process to minimize the scope of files that can be deleted, ensuring it runs with the least privileges necessary. Implement monitoring and alerting on file deletion events and unusual activity on the server hosting ConvertX. Conduct regular backups of critical files and configurations to enable rapid recovery in case of malicious deletion. Finally, perform security assessments and code reviews on custom or third-party web applications to detect similar path traversal vulnerabilities proactively.

Description

CVE-2026-24741 is a high-severity path traversal vulnerability in C4illin ConvertX versions prior to 0.17.0. The vulnerability exists in the POST /delete endpoint, where the user-controlled filename parameter is used without proper validation to delete files via unlink. Attackers can exploit this by supplying path traversal sequences (e.g. , .. /) to delete arbitrary files outside the intended directory, constrained only by the server process permissions. This can lead to significant integrity and availability impacts on affected systems. The issue is fixed in version 0.
