      <title>CVE-2026-63458 — Perses project query parameter authorization bypass exposes cross-project resources</title>
      <link>https://db.gcve.eu/vuln/cve-2026-63458</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; perses&lt;/p&gt;
&lt;p&gt;Perses is an open-source dashboard and visualization project for observability data. Prior to 0.54.0-beta.3, an authenticated user with viewer access to one project can supply another project through the project query parameter on project-scoped list endpoints, including /api/v1/projects/{project}/dashboards and /api/v1/datasources. The request-controlled project value is used to select dashboards, datasources, and variables without enforcing the caller&amp;#39;s authorization for that selected project, which breaks project-level tenant isolation and exposes complete resource specifications belonging to other projects. This issue is fixed in version 0.54.0-beta.3.&lt;/p&gt;</description>
