CVE-2025-15483: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ajferg Link Hopper
The Link Hopper plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘hop_name’ parameter in all versions up to, and including, 2.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
AI Analysis
Technical Summary
The Link Hopper plugin for WordPress suffers from a stored XSS vulnerability (CWE-79) via the 'hop_name' parameter due to improper neutralization of input during web page generation. This vulnerability affects multi-site installations with unfiltered_html disabled and requires administrator-level privileges to exploit. The vulnerability allows injection of arbitrary web scripts that execute in the context of users viewing the injected pages. The CVSS 3.1 vector indicates network attack vector, high attack complexity, high privileges required, no user interaction, and impacts confidentiality and integrity with no availability impact.
Potential Impact
An authenticated attacker with administrator privileges on a multi-site WordPress installation can inject malicious scripts via the 'hop_name' parameter. These scripts execute in the browsers of users who visit the affected pages, potentially leading to information disclosure or integrity violations within the affected site context. The impact is limited to confidentiality and integrity with no direct availability impact. This vulnerability does not affect single-site installations or those with unfiltered_html enabled.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Administrators should review plugin usage on multi-site WordPress installations and consider restricting administrator access or disabling the Link Hopper plugin until a fix is released. Monitor the vendor's advisory channels for updates. Since this vulnerability requires administrator privileges and specific configuration (multi-site with unfiltered_html disabled), limiting administrative access and carefully controlling plugin installations can reduce risk.
