CVE-2024-12203: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in brandondove RSS Icon Widget
The RSS Icon Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘link_color’ parameter in all versions up to, and including, 5.2 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 RSS Icon Widget plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) via the 'link_color' parameter. Authenticated users with administrator privileges can inject arbitrary scripts due to improper input neutralization during page generation. This vulnerability affects multi-site installations or those with unfiltered_html disabled, in all plugin versions up to 5.2. The CVSS 3.1 base score is 4.4, reflecting network attack vector, high attack complexity, high privileges required, no user interaction, and partial impact on confidentiality and integrity. No patch or remediation is currently available from the vendor.
Potential Impact
An attacker with administrator-level access on affected WordPress installations can inject malicious scripts that execute in the context of users accessing the injected pages. This can lead to partial compromise of confidentiality and integrity of the affected site. The vulnerability does not impact availability. Exploitation is limited to multi-site or unfiltered_html-disabled environments and requires high privileges, reducing the overall risk.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrator access to trusted users only and consider disabling or removing the RSS Icon Widget plugin in multi-site or unfiltered_html-disabled environments. Monitor official vendor channels for updates or patches addressing this vulnerability.
