CVE-2026-49466 in Draft List Plugin
Summary
by MITRE • 08/12/2026
Draft List is a WordPress plugin to manage and promote unpublished content. Versions 2.6.3 and below are vulnerable to stored Cross-Site Scripting (XSS) in the `[drafts]` shortcode and Draft List widget when the documented custom `template` option places the `{{draft}}` placeholder inside an HTML attribute. The vulnerable code inserts the raw draft `post_title` into `{{draft}}` when the current viewer cannot edit posts. Because the template is sanitized before `{{draft}}` replacement, a Contributor can store a quote-only title payload that breaks out of an attribute in a site-configured Draft List template and executes JavaScript for visitors who load the public page. Version 2.6.4 fixes the issue.

The Draft List WordPress plugin presents a significant security vulnerability through stored cross-site scripting attacks that can compromise user sessions and execute malicious code on victim browsers. This vulnerability specifically affects versions 2.6.3 and earlier, where the plugin's handling of draft content templates creates an opening for attackers to inject persistent JavaScript payloads. The flaw manifests within the `[drafts]` shortcode and Draft List widget functionality when administrators configure custom templates containing the `{{draft}}` placeholder inside HTML attributes, creating a direct pathway for malicious input to be executed as code.
The technical mechanism behind this vulnerability stems from improper input sanitization and output escaping practices within the plugin's template processing logic. When a contributor user creates a post with a specially crafted title containing JavaScript code, the system stores this content unfiltered in the database. During template rendering, the raw `post_title` value gets inserted into the `{{draft}}` placeholder without adequate HTML entity encoding or context-appropriate escaping. This allows malicious payloads to break out of their intended text context and execute within HTML attributes, bypassing standard security measures that typically protect against such attacks.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to perform session hijacking, defacement, and data exfiltration attacks against unsuspecting visitors. The stored nature of the XSS means that once a malicious payload is injected into a draft title and published, it persists in the system until manually removed, continuously affecting all users who view pages containing the vulnerable shortcode or widget. This creates a persistent threat vector that can be exploited by attackers with minimal privileges, as contributor-level users can manipulate content templates to inject malicious code.
This vulnerability aligns with CWE-79 (Cross-site Scripting) and follows patterns commonly found in web application security flaws where insufficient output escaping creates opportunities for attackers to inject malicious payloads. The attack vector demonstrates characteristics consistent with ATT&CK technique T1566.001 (Phishing: Spearphishing Attachment) as attackers can craft malicious draft titles that appear legitimate but execute harmful scripts when viewed by other users. The exploitation requires only contributor-level privileges, making it particularly dangerous as it can be leveraged by users who should normally have restricted capabilities within the WordPress environment.
The fix implemented in version 2.6.4 addresses this vulnerability through proper input sanitization and output escaping mechanisms that ensure all draft content is properly encoded before insertion into HTML attributes. Security researchers and system administrators should immediately update to version 2.6.4 or later to protect against exploitation, while monitoring for any indicators of compromise in affected installations. Organizations using this plugin should also review their contributor user permissions and implement additional security measures such as content filtering and regular audit checks to detect potential malicious activity within draft content areas.
The vulnerability highlights the importance of context-aware output escaping in web applications and demonstrates why proper input validation should occur at multiple layers of application processing. It underscores the need for developers to consider all possible contexts where user-provided data may be rendered, particularly when dealing with template systems that allow for dynamic content insertion. This case study serves as a reminder that even seemingly benign plugin functionalities can create significant security risks when proper sanitization practices are not implemented throughout the entire code execution path.
