Alert meAnalysisAI
In Wiki.js before version 2.5.151, directory traversal outside of Wiki.js context is possible when a storage module with local asset cache fetching is enabled. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Path Traversal vulnerability could allow attackers to access files and directories outside the intended path.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Validate and canonicalize file paths. Use chroot or sandboxing. Reject input containing path separators or '../' sequences.

Technical ContextAI · show details
This vulnerability is classified as Path Traversal (CWE-22), which allows attackers to access files and directories outside the intended path. In Wiki.js before version 2.5.151, directory traversal outside of Wiki.js context is possible when a storage module with local asset cache fetching is enabled. A malicious user can potentially read any file on the file system by crafting a special URL that allows for directory traversal. This is only possible when a storage module implementing local asset cache (e.g Local File System or Git) is enabled and that no web application firewall solution (e.g. cloudflare) strips potentially malicious URLs. Commit 084dcd69d1591586ee4752101e675d5f0ac6dcdc fixes this vulnerability by sanitizing the path before it is passed on to the storage module. The sanitization step removes any directory traversal (e.g. .. and .) sequences as well as invalid filesystem characters from the path. As a workaround, disable any storage module with local asset caching capabilities such as Local File System and Git. Affected products include: Requarks Wiki.Js. Version information: version 2.5.151.
