## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-rpx2-p6hp-x5gj. This link is maintained to preserve external references. ## Original Description SiYuan 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.
