CVE-2026-100520: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in crivion Laranode
Laranode versions before 1.2.1 contain a path traversal vulnerability in the POST /filemanager/upload-file endpoint that allows authenticated users to write arbitrary files outside their home directory. Attackers can supply directory traversal sequences in the path parameter to write PHP files into other tenants' web roots and execute code as those tenants.
AI Analysis
Technical Summary
CVE-2026-100520 is a path traversal vulnerability (CWE-22) in crivion's Laranode product affecting versions prior to 1.2.1. The flaw exists in the POST /filemanager/upload-file endpoint, where authenticated users can manipulate the path parameter to escape their restricted directory and write files arbitrarily on the server. This enables attackers to upload malicious PHP files into other tenants' web root directories, resulting in remote code execution under the context of those tenants.
Potential Impact
Successful exploitation allows authenticated users to write arbitrary files outside their authorized directories, leading to remote code execution in the context of other tenants. This compromises tenant isolation and can result in full compromise of affected tenants' web applications and data.
Mitigation Recommendations
Upgrade Laranode to version 1.2.1 or later where this vulnerability is fixed. Since the vulnerability is patched in 1.2.1, applying this official fix fully mitigates the issue.
