2DescriptionCVE.org
SiYuan is an open-source personal knowledge management system. Prior to 3.7.0, the patch for CVE-2026-41894 ("Path Traversal via Double URL Encoding") sanitized the /export/ route but the identical root cause remains in the /assets/*path route. In publish mode (anonymous read-only HTTP endpoint, default port 6808), an unauthenticated remote attacker can read arbitrary files inside WorkspaceDir - including conf/conf.json (which contains the AccessAuthCode SHA256 hash, API token, and sync keys), temp/siyuan.db, temp/blocktree.db, and siyuan.log - by double-URL-encoding .. segments. This vulnerability is fixed in 3.7.0.
AnalysisAI
Arbitrary file disclosure in SiYuan personal knowledge management system before 3.7.0 lets an unauthenticated remote attacker read any file inside the workspace directory through its publish-mode HTTP endpoint (default port 6808). The flaw is an incomplete fix for CVE-2026-41894: the earlier patch sanitized the /export/ route but left the identical double-URL-encoding path traversal in the /assets/*path route, exposing conf/conf.json (AccessAuthCode SHA256 hash, API token, sync keys), the temp SQLite databases, and siyuan.log. Publicly available exploit code exists; no public active exploitation has been confirmed.
Technical ContextAI
SiYuan is a self-hosted, open-source note-taking and knowledge-management application written in Go that serves content over an embedded HTTP server. In publish mode it exposes an anonymous, read-only endpoint (default port 6808) so notebooks can be shared without authentication. The vulnerability is CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). The /assets/*path handler resolves a user-supplied path relative to the workspace, but it decodes percent-encoded input such that double-URL-encoded '..' sequences (e.g. %252e%252e) survive a single normalization pass and resolve to parent directories. The affected component is cpe:2.3:a:siyuan-note:siyuan, all versions prior to 3.7.0. Because the prior CVE-2026-41894 patch only hardened the /export/ route, the same decoding weakness persisted unaddressed in the assets route.
RemediationAI
Vendor-released patch: upgrade SiYuan to version 3.7.0 or later, which fixes the double-URL-encoding path traversal in the /assets/*path route; see the advisory at https://github.com/siyuan-note/siyuan/security/advisories/GHSA-p4m3-mgmm-c664. If immediate upgrade is not possible, disable publish mode so the anonymous endpoint is not served, which removes the unauthenticated attack surface at the cost of losing public notebook sharing. Alternatively, restrict network access to the publish-mode port (default 6808) using a firewall or reverse proxy allowlist so only trusted clients can reach it, and place the endpoint behind an authenticating proxy; note this breaks anonymous sharing for legitimate external users. Because the exposed conf/conf.json may have already leaked secrets, after patching rotate the API token, sync keys, and reset the AccessAuthCode, since prior exposure cannot be ruled out.
