CVE-2026-45230: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in DumbWareio DumbAssets
DumbAssets through 1.0.11 contains a path traversal vulnerability in the POST /api/delete-file endpoint and filesToDelete array parameters that allows unauthenticated attackers to delete arbitrary files by supplying ../ sequences that bypass directory boundary validation. Attackers can exploit the optional and disabled-by-default authentication control to traverse outside the intended application directory and delete critical files such as server.js or package.json, causing complete denial of service.
AI Analysis
Technical Summary
CVE-2026-45230 is a path traversal vulnerability in DumbAssets through version 1.0.11. The issue exists in the POST /api/delete-file endpoint and the filesToDelete array parameter, where directory boundary validation is insufficient. Attackers can supply ../ sequences to traverse outside the intended directory and delete arbitrary files without authentication, as the authentication control is optional and disabled by default. This can cause critical files to be deleted, leading to denial of service.
Potential Impact
Successful exploitation allows unauthenticated attackers to delete arbitrary files on the server, including critical application files like server.js and package.json. This results in complete denial of service of the affected application.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, it is recommended to enable and enforce authentication controls if possible and restrict access to the vulnerable endpoint. Monitor for updates from DumbWareio regarding an official fix.
