CVE-2021-23263Network attack vector

Unauthenticated textual file disclosure through FreeMarker

Published Dec 2, 2021 · Updated Sep 16, 2024

Information disclosure in CrafterEngine 3.1 before 3.1.15 allows remote attackers to read textual project files through FreeMarker. FreeMarker resource handling exposes files under /scripts and /templates and some nonbinary files under /.git; the vendor has not disclosed the exact flawed resolver or operation. No authentication or user interaction is required, but the published impact is limited to reading textual content rather than modifying data or interrupting service.
