CVE-2026-1401: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in jackdewey Tune Library
The Tune Library plugin for WordPress is vulnerable to Stored Cross-Site Scripting via CSV import in all versions up to, and including, 1.6.3. This is due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the injected page. The vulnerability exists because the CSV import functionality lacks authorization checks and doesn't sanitize imported data, which is later rendered without escaping through the [tune-library] shortcode.
AI Analysis
Technical Summary
CVE-2026-1401 is a stored cross-site scripting vulnerability in the Tune Library WordPress plugin (versions up to 1.6.3). The flaw exists because the CSV import functionality lacks authorization checks and fails to sanitize user-supplied attributes, allowing authenticated users with low privileges to inject arbitrary scripts. These scripts are rendered without proper escaping through the [tune-library] shortcode, leading to script execution in users' browsers. The CVSS 3.1 base score is 6.4, indicating a medium severity vulnerability with network attack vector, low attack complexity, and no user interaction required.
Potential Impact
An attacker with Subscriber-level or higher access can inject malicious scripts that execute in the context of other users viewing the affected pages. This can lead to information disclosure and integrity impacts as indicated by the CVSS vector (confidentiality and integrity impacts are low, availability is not affected). The vulnerability does not require user interaction and can be exploited remotely over the network.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict CSV import functionality to trusted users only and consider disabling the Tune Library plugin if possible. Monitor for updates from the vendor and apply any official patches promptly once available.
