CVE-2026-41459
MediumCVSS 5.3Exploitation Probability (EPSS)
Elevated risk52th percentile - higher than 52% of all known CVEs
Summary
Xerte Online Toolkits versions 3.15 and earlier contain an information disclosure vulnerability that allows unauthenticated attackers to retrieve the full server-side filesystem path of the application root. Attackers can send a GET request to the /setup page to access the exposed root_path value rendered in the HTML response.
Risk Assessment
Exposing the system path facilitates exploitation of path-dependent vulnerabilities such as relative path traversal in connector.php, potentially leading to unauthorized file access.
Recommendation
Immediately update Xerte Online Toolkits to a version later than 3.15 which fixes this vulnerability. Until then, restrict access to the /setup page using firewall rules or authentication.
Other vulnerabilities in Xerte Online Toolkits
See all- CVE-2026-34415Critical
Xerte Online Toolkits versions 3.15 and earlier have an incomplete input validation vulnerability in the elFinder connector endpoint that fails to block the .php4 extension due to an incorrect regex pattern. Unauthenticated attackers can exploit this flaw combined with authentication bypass and path traversal to upload malicious PHP code and execute arbitrary system commands on the server.
- CVE-2026-34414High
A relative path traversal vulnerability in Xerte Online Toolkits versions 3.15 and earlier allows attackers to move files from project media directories to arbitrary filesystem locations via an unsanitized 'name' parameter in the rename command of the elFinder connector. This can lead to overwriting application files, stored cross-site scripting, or when combined with other vulnerabilities, unauthenticated remote code execution by moving PHP files to the application root.
- CVE-2026-34413High
Xerte Online Toolkits versions 3.15 and earlier have a missing authentication vulnerability in the elFinder connector endpoint. An HTTP redirect to unauthenticated callers does not call exit() or die(), allowing PHP execution to continue and process the full request server-side.
