CVE-2026-53528: CWE-23: Relative Path Traversal in perber leafwiki
Description
LeafWiki versions 0.3.0 through 0.10.0 contain a relative path traversal vulnerability in the asset rename functionality. An authenticated user with editor permissions can exploit this flaw to move files accessible to the LeafWiki server into a page's asset directory, potentially exposing sensitive local files such as the application database. Version 0.10.1 and later address this issue. Operators should run LeafWiki with least privilege and restrict editor access until patched.

Technical Analysis
CVE-2026-53528 is a relative path traversal vulnerability (CWE-23) in LeafWiki's asset rename feature affecting versions 0.3.0 through 0.10.0. An authenticated editor can move arbitrary files accessible by the server process into a page asset directory, enabling unauthorized download of sensitive files like the application database. This vulnerability arises from insufficient validation of file paths during asset renaming. The issue is fixed in LeafWiki version 0.10.1.
Potential Impact
Successful exploitation allows an authenticated user with editor privileges to access and download sensitive local files by moving them into publicly accessible asset directories. This compromises confidentiality, integrity, and availability of the application data, including the database. The CVSS 3.1 score is 8.8 (high severity), reflecting network attack vector, low attack complexity, required privileges, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
A fix is available in LeafWiki version 0.10.1 and later; users should update promptly. Until patched, operators should restrict editor permissions to trusted users only and run the LeafWiki process with the least privileges necessary, ensuring it does not have access to sensitive files outside required directories.
