CVE-2025-12538: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in iworks Fleet Manager
The Fleet Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.5.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-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 Fleet Manager plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Authenticated users with editor or higher privileges can inject arbitrary scripts through the plugin's admin settings. These scripts execute when any user accesses the affected pages. The issue specifically affects multi-site WordPress setups or installations with unfiltered_html disabled. The vulnerability has a CVSS v3.1 base score of 4.4, reflecting a medium impact with network attack vector, high attack complexity, and no user interaction required. There is no vendor-provided patch or advisory available at this time.
Potential Impact
Successful exploitation allows an authenticated user with editor-level or higher permissions to inject persistent malicious scripts into pages managed by the Fleet Manager plugin. This can lead to limited confidentiality and integrity impacts, such as session hijacking or unauthorized actions performed in the context of other users viewing the injected pages. The vulnerability does not affect availability. The scope is limited to multi-site WordPress installations or those with unfiltered_html disabled, reducing the overall attack surface.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict editor-level permissions to trusted users only and consider disabling or limiting use of the Fleet Manager plugin in multi-site environments or where unfiltered_html is disabled. Monitor vendor channels for updates and apply patches promptly once available.
