Security readout for executives and security teams
Plain-English summary
CVE-2015-10101 is a cross-site scripting issue in the WordPress Google Analytics Top Content Widget Plugin through version 1.5.6. It could let an authenticated remote attacker affect page integrity. Sources identify version 1.5.7 as the fix. No provided source reports active exploitation.
Executive priority
Treat this as a moderate maintenance risk, not an emergency unless the plugin is present on important public WordPress sites. The known fix is straightforward: upgrade to 1.5.7 or remove the plugin.
Technical view
The vulnerability is CWE-79 in class-tgm-plugin-activation.php within Google Analytics Top Content Widget Plugin versions 1.5.0 through 1.5.6. CVSS v2 is 4.0 with network access, low complexity, authentication required, partial integrity impact, and no confidentiality or availability impact. Patch reference is commit 25bb1dea113716200a6f0f3135801d84a7a65540.
Likely exposure
Exposure is likely limited to WordPress sites that have this specific plugin installed at versions 1.5.6 or earlier. Sites without the plugin, or already upgraded to 1.5.7, are not indicated as affected by the supplied sources.
Exploitation context
The source bundle says the attack can be launched remotely, but the CVSS vector requires authentication. KEV is false, and no cited source states active exploitation. The affected functionality is described only as unknown, so precise attack preconditions are incomplete.
Researcher notes
The public description does not identify the exact parameter, route, or function involved, only the file name and XSS class. Avoid assuming unauthenticated exploitability; the CVSS vector states authentication is required. Validate exposure by plugin version and patch presence.
Mitigation direction
- Upgrade Google Analytics Top Content Widget Plugin to version 1.5.7.
- Remove or disable the plugin if it is unused or cannot be upgraded.
- Prioritize externally reachable WordPress sites with authenticated user access.
- Check vendor and WordPress plugin guidance for any additional remediation details.
Validation and detection
- Inventory WordPress sites for Google Analytics Top Content Widget Plugin installations.
- Confirm installed versions are 1.5.7 or later.
- Check whether class-tgm-plugin-activation.php includes the referenced patch commit changes.
- Document any affected site that cannot be upgraded immediately.
- Review authenticated WordPress user access on affected sites.
