CVE-2026-116168SiYuan before 3.8.7 contains a path traversal vulnerability in the MCP asset tool because validateAssetUploadPaths relies on an incomplete sensitive-path blacklist that omits... Executive summary SiYuan, a self-hosted note-taking application, has a path traversal flaw in its MCP asset upload tool that lets an agent-facing caller copy sensitive files from the host, such as a home-directory .env file, into the workspace where they can be read back. The advisory rates it High. The advisory says the fix to be applied is version 3.8.7 and that the vendor's patch is incomplete, since the earlier sensitive-path blacklist omits some secret-bearing filenames. Technical summary The weakness is CWE-22 path traversal with information exposure (CWE-200): the MCP asset upload tool passes file paths through a sensitive-path blacklist (util.IsSensitivePath) that does not cover names such as .env, so a local file is copied into the workspace data/assets directory and served back over HTTP to authenticated sessions. The advisory states affected versions are 3.8.6 and earlier (<= 3.8.6) and the patched version is v3.8.7, but it describes the v3.8.7 fix as incomplete, and it does not state whether 3.8.7 itself fully resolves the issue. Preconditions include an API token for an agent or admin principal driving the MCP server and a file readable by the server process. The advisory's proof of concept was run against v3.8.6 in a Docker lab, and it reports the upload succeeded under the fixed build. No workarounds are stated. No detection guidance is stated. No CVE ID is assigned in the advisory. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
