      <title>CVE-2025-24018 — YesWiki Vulnerable to Authenticated Stored XSS</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2025-24018</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; yeswiki&lt;/p&gt;
&lt;p&gt;YesWiki is a wiki system written in PHP. In versions up to and including 4.4.5, it is possible for an authenticated user with rights to edit/create a page or comment to trigger a stored XSS which will be reflected on any page where the resource is loaded. The vulnerability makes use of the content edition feature and more specifically of the `{{attach}}` component allowing users to attach files/medias to a page. When a file is attached using the `{{attach}}` component, if the resource contained in the `file` attribute doesn&amp;#39;t exist, then the server will generate a file upload button containing the filename. This vulnerability allows any malicious authenticated user that has the right to create a comment or edit a page to be able to steal accounts and therefore modify pages, comments, permissions, extract user data (emails), thus impacting the integrity, availability and confidentiality of a YesWiki instance. Version 4.5.0 contains a patch for the issue.&lt;/p&gt;</description>
