Textpattern

Textpattern CMS 4.9.0 contains a Broken Access Control vulnerability in the article management system that allows authenticated users with low privileges to modify articles owned by users with higher privileges. By manipulating the article ID parameter during the duplicate-and-save workflow in textpattern/include/txp_article.php, an attacker can bypass authorization checks and overwrite content belonging to other users.Show less

Textpattern CMS version 4.9.0 contains a second-order cross-site scripting vulnerability that allows attackers to inject malicious scripts by exploiting improper sanitization of user-supplied input in Atom feed XML elements. Attackers can embed unescaped payloads in parameters such as category that are reflected into Atom fields like and , which execute as JavaScript when feed readers or CMS aggregators consume the feed and insert content into the DOM using unsafe methods.Show less

Textpattern CMS 4.8.8 contains a stored cross-site scripting vulnerability in the article excerpt field that allows authenticated users to inject malicious scripts. Attackers can insert JavaScript payloads into the excerpt, which will execute when the article is viewed by other users.Show less

Textpattern CMS v4.8.7 and older vulnerability exists through Sensitive Cookie in HTTPS Session Without 'Secure' Attribute via textpattern/lib/txplib_misc.php. The secure flag is not set for txp_login session cookie in the application. If the secure flag is not set, then the cookie will be transmitted in clear-text if the user visits any HTTP URLs within the cookie's scope. An attacker may be able to induce this event by feeding a user suitable links, either directly or via another web site.Show less

textpattern 4.8.7 is vulnerable to Cross Site Scripting (XSS) via /textpattern/index.php,Body. A remote and unauthenticated attacker can use XSS to trigger remote code execution by uploading a webshell. To do so they must first steal the CSRF token before submitting a file upload request.Show less

A cross-site scripting vulnerability was discovered in the Comments parameter in Textpattern CMS 4.8.4 which allows remote attackers to execute arbitrary code via a crafted payload entered into the URL field.
