CVE-2026-113664 Details
Description
ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.0 of the import-export module, an authenticated importer can submit a tar entry whose normalized destination targets a directory while bypassing the literal parent-path substring guard. Opening that directory as a write stream emits an unhandled filesystem error that can terminate the Node.js process; the source establishes this static primitive but not an end-to-end exploit or controlled arbitrary file read or write. This issue is fixed in version 3.7.0.
A directory traversal vulnerability has been identified in the ApostropheCMS import-export module, affecting versions prior to 3.7.0. The issue allows an authenticated importer to upload a tar entry that bypasses the normal parent-path guard, targeting a directory instead. This misstep leads to an unhandled filesystem error when the directory is opened as a write stream, causing the Node.js process to terminate. While this vulnerability does not currently allow for controlled arbitrary file read or write operations, it does exploit a static primitive that could be leveraged in such a manner.
Users can update to ApostropheCMS import-export version 3.7.0 or later, where this vulnerability has been patched.
