This affects the function rename of the file /editor/elfinder/php/connector.php of the component elFinder Connector Endpoint. Such manipulation of the argument Name leads to path traversal. This vulnerability is listed as CVE-2026-34414. The attack may be performed from remote. There is no available exploit. It is suggested to upgrade the affected component. Detailsinfo A vulnerability, which was classified as critical, has been found in thexerteproject xerteonlinetoolkits up to 3.13.0/3.14.0/3.15.0. Affected by this issue is the function rename of the file /editor/elfinder/php/connector.php of the component elFinder Connector Endpoint. The manipulation of the argument name with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. CVE summarizes: Xerte Online Toolkits versions 3.15 and earlier contain a relative path traversal vulnerability in the elFinder connector endpoint at /editor/elfinder/php/connector.php where the name parameter in rename commands is not sanitized for path traversal sequences. Attackers can supply a name value containing directory traversal sequences to move files from project media directories to arbitrary locations on the filesystem, potentially overwriting application files, achieving stored cross-site scripting, or combining with other vulnerabilities to achieve unauthenticated remote code execution by moving PHP code files to the application root.
