CVE-2026-4805: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in duongancol Woostify
The Woostify plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.5.0 This is due to insufficient input sanitization and output escaping in the bundled Lity.js lightbox library, where user-controlled input from the href attribute is concatenated directly into a jQuery HTML string without sanitization. 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.
AI Analysis
Technical Summary
CVE-2026-4805 is a stored cross-site scripting vulnerability in the Woostify WordPress plugin (versions up to 2.5.0). The issue arises from insufficient sanitization and escaping of user input in the href attribute within the bundled Lity.js lightbox library. Authenticated attackers with Contributor-level privileges or higher can inject arbitrary JavaScript code into pages, which executes when other users access those pages. This vulnerability can lead to partial compromise of confidentiality and integrity but does not affect availability. The CVSS 3.1 base score is 6.4 (medium severity). No patch or official remediation has been documented as of the publication date.
Potential Impact
Successful exploitation allows authenticated users with Contributor-level access or above to inject persistent malicious scripts into pages. This can lead to unauthorized actions performed in the context of other users viewing the injected content, potentially compromising confidentiality and integrity of user data. There is no impact on availability. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider disabling or replacing the Woostify plugin if possible. Monitor vendor channels for updates and apply patches promptly once available.
