CVE-2024-9169: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in litespeedtech LiteSpeed Cache
The LiteSpeed Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via plugin debug settings in all versions up to, and including, 6.4.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, 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 LiteSpeed Cache WordPress plugin versions up to 6.4.1 contain a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in plugin debug settings. Authenticated administrators can inject malicious scripts that persist and execute in the context of users visiting the injected pages. This vulnerability affects multi-site setups or installations with unfiltered_html disabled, increasing the risk of persistent script injection. The CVSS 3.1 base score is 5.5, reflecting medium severity with low complexity for an attacker who already has high privileges. No patch or official fix information is currently available.
Potential Impact
An attacker with administrator-level access can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin debug settings. This can lead to limited confidentiality and integrity impacts, such as executing arbitrary scripts in the context of other users, potentially leading to session hijacking or unauthorized actions. There is no indication of availability impact. The vulnerability is limited to multi-site or restricted HTML capability environments and requires high privileges, reducing the attack surface.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit administrator access to trusted users only and consider disabling or restricting the use of plugin debug settings in multi-site or unfiltered_html-disabled environments. Monitor official LiteSpeed Cache communications for updates on patches or mitigations.
