CVE-2026-40318

SiYuan prior to 3.6.4 is affected by a server-side path traversal in the /api/av/removeUnusedAttributeView endpoint, where the user-controlled id is concatenated into a path (via filepath.Join(util.DataDir, "storage", "av", id+".json")) without boundary checks. An attacker can supply traversal se...

SiYuan 安全漏洞

These vulnerabilities stemmed from the /api/av/removeUnusedAttributeView endpoint, which used a user-controlled id parameter to construct fil...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the removeUnusedAttributeView process. An attacker can delete arbitrary .json files within the workspace by supplying crafted path traversal sequences in the id parameter, allowing removal of files outside the...
