CVE-2025-15522 in Uncanny Automator Plugin
Summary
by MITRE • 01/23/2026
The Uncanny Automator – Easy Automation, Integration, Webhooks & Workflow Builder Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the automator_discord_user_mapping shortcode in all versions up to, and including, 6.10.0.2 due to insufficient input sanitization and output escaping on the verified_message parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user with a verified Discord account accesses the injected page.

The vulnerability identified as CVE-2025-15522 affects the Uncanny Automator WordPress plugin, specifically targeting version 6.10.0.2 and earlier releases. This issue manifests as a stored cross-site scripting vulnerability within the automator_discord_user_mapping shortcode functionality. The flaw resides in the plugin's inadequate handling of user input, particularly in the verified_message parameter which fails to undergo proper sanitization and output escaping processes. Security researchers have identified that this vulnerability can be exploited by authenticated attackers who possess at least Contributor-level privileges within the WordPress environment.
The technical exploitation of this vulnerability occurs through the manipulation of the verified_message parameter within the automator_discord_user_mapping shortcode implementation. When an authenticated attacker with appropriate permissions injects malicious script code into this parameter, the malicious payload gets stored within the WordPress database. This stored script becomes persistent and executes whenever any user with a verified Discord account accesses a page containing the affected shortcode. The vulnerability operates under CWE-79 which classifies it as a cross-site scripting flaw, specifically a stored XSS variant where the malicious input is permanently saved and executed against other users.
The operational impact of this vulnerability extends beyond simple script execution as it creates a persistent threat vector within the WordPress environment. Attackers can leverage this weakness to execute arbitrary JavaScript code in the context of the victim's browser, potentially leading to session hijacking, credential theft, or redirection to malicious websites. The requirement for Contributor-level access or higher means that attackers who have gained access to user accounts with sufficient privileges can create a long-term threat that affects all users with verified Discord accounts. This attack vector particularly concerns administrators and content creators who may have elevated permissions and are more likely to interact with pages containing the vulnerable shortcode.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1566.002 which covers "Phishing: Spearphishing Attachment" and T1566.001 which covers "Phishing: Spearphishing Link". The stored nature of the XSS payload means that successful exploitation can affect multiple users without requiring repeated attacks, making it particularly dangerous in environments where multiple users interact with the same content. The vulnerability represents a significant risk to WordPress sites that utilize Discord integration features and have users with Contributor or higher privileges. Organizations should consider implementing additional security controls beyond the standard WordPress security measures, including content security policy implementations and regular security audits of plugin installations.
Mitigation strategies for this vulnerability include immediate patching of the affected plugin to version 6.10.0.3 or later, which should contain the necessary input sanitization and output escaping fixes. Administrators should also implement role-based access controls to limit the number of users with Contributor-level or higher privileges, reducing the attack surface. Additional defensive measures include implementing content security policies that restrict script execution, monitoring for suspicious shortcode usage, and conducting regular security assessments of all installed plugins. The vulnerability demonstrates the importance of proper input validation and output escaping practices in web applications, particularly those handling user-generated content and integration with third-party services.
