This link is maintained to preserve external references.\n\n## Original Description\nSiYuan versions before v3.7.4 fail to validate that packageName matches the downloaded package content in bazaar install endpoints. Attackers with same-origin access can overwrite existing trusted plugins by supplying mismatched packageName and repoURL parameters, achieving persistence across application restarts.\n\n## Affected packages\n\n- `github.com/siyuan-note/siyuan/kernel < 3.7.4`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":36.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
