CVE-2026-1805 in DA Media GigList Plugin
Summary
by MITRE • 03/07/2026
The DA Media GigList plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's damedia_giglist shortcode in all versions up to, and including, 1.9.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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 accesses an injected page.

The DA Media GigList plugin for WordPress presents a critical stored cross-site scripting vulnerability identified as CVE-2026-1805, affecting all versions up to and including 1.9.0. This vulnerability stems from inadequate input sanitization and output escaping mechanisms within the plugin's damedia_giglist shortcode implementation, creating a persistent security weakness that can be exploited by authenticated attackers. The flaw specifically targets user-supplied attributes within the shortcode functionality, allowing malicious actors to inject malicious scripts that execute in the context of other users' browsers when they access pages containing the compromised content.
The technical exploitation of this vulnerability occurs through the plugin's insufficient validation of input parameters passed to the damedia_giglist shortcode. When authenticated users with contributor-level privileges or higher create or modify content containing the vulnerable shortcode with malicious attributes, the plugin fails to properly sanitize these inputs before storing them in the database. This stored malicious content remains dormant until accessed by other users, at which point the injected scripts execute in their browsers, potentially leading to session hijacking, data theft, or further compromise of the affected WordPress installation. The vulnerability operates under CWE-79 which specifically addresses cross-site scripting flaws where insufficient input sanitization allows malicious code injection.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to leverage the privileges of authenticated users to perform actions that would otherwise be restricted. Contributors and above typically have the ability to create and edit posts, which when combined with this XSS vulnerability, allows attackers to inject malicious code into pages that will execute for other users with varying permission levels. This creates a persistent threat vector where attackers can establish backdoors, steal user credentials, manipulate content, or redirect users to malicious sites. The vulnerability is particularly concerning in multi-user environments where contributors may have access to sensitive information or content management capabilities.
Mitigation strategies for CVE-2026-1805 should prioritize immediate plugin updates to versions that address the input sanitization and output escaping deficiencies. Organizations should implement comprehensive security monitoring to detect unauthorized shortcode modifications and establish strict content review processes for all user-generated content. Network-level protections such as web application firewalls can help detect and block malicious payload delivery, while regular security audits should verify that all plugins and themes maintain proper input validation and output escaping practices. The ATT&CK framework categorizes this vulnerability under T1059.005 for command and scripting interpreter, as attackers can use the XSS to execute malicious scripts in victim browsers, and T1547.001 for registry run keys for persistence mechanisms that could be established through the compromised user sessions.
