EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 4.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5% (39th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

SiYuan is an open-source personal knowledge management system. Prior to 3.7.1, POST /api/file/globalCopyFiles accepts attacker-supplied absolute source paths and relies on util.IsSensitivePath in kernel/util/path.go, whose denylist misses common home-directory credential files such as .git-credentials, .netrc, .pgpass, .kube/config, .docker/config.json, and .gnupg, allowing an authenticated administrator or API-token user to copy those files into the workspace and exfiltrate them through the file API. This issue is fixed in versions 3.7.1-alpha.2 and 3.7.1.
