GHSA-9cqf-hhrq-7v45: SiYuan: getAttributeViewSearchTarget returns database row content to anonymous readers with no publish-access check, reopening the class closed one day earlier at the adjacent route

/api/av/getAttributeViewSearchTarget is registered with CheckAuth only and performs no authorization of any kind. Given a database identifier and a keyword, it searches that database’s rows and returns matching content, regardless of whether the caller may see the database, the rows, or the notebook holding them.

Commit 64c26e74b on 2026-07-26 closed a reader-reachable gap on getAttributeViewFieldViews by adding CheckReadonly at router line 536. 9b8e8956f, the following day, registered this endpoint at line 535 without it. The new route returns more than the one that was just closed: row content rather than field-visibility metadata.
