Textpattern Cms
Monthly
TextPattern CMS 4.9.0-dev contains a remote code execution vulnerability that allows authenticated attackers to upload arbitrary PHP files by exploiting the plugin upload functionality. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
TextPattern CMS 4.8.7 contains a remote code execution vulnerability that allows authenticated attackers to execute arbitrary commands by uploading malicious PHP files through the file upload. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
A second-order XSS vulnerability exists in Textpattern CMS version 4.9.0 where user-supplied input (such as category parameters) is improperly sanitized and lacks contextual XML escaping in Atom feed XML elements like <id> and <link href>. While the payload does not execute directly in raw XML contexts within modern browsers, it becomes exploitable when feed readers, admin dashboards, or CMS aggregators consume the feed and insert its content into the DOM using unsafe methods like innerHTML, resulting in arbitrary JavaScript execution in a trusted context. A public proof-of-concept exploit is available, making this an active threat to administrators and users consuming feeds from vulnerable Textpattern instances.
