## Overview

## 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This advisory has been withdrawn because it is a duplicate of GHSA-rpx2-p6hp-x5gj.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.

## Affected packages

- `github.com/siyuan-note/siyuan/kernel < 3.7.4`

## Remediation

Refer to the advisory for the patched release.
