Lifecycle Timeline
5DescriptionCVE.org
The Site Kit by Google WordPress plugin before 1.176.0 does not properly restrict a REST API write endpoint to administrators, allowing lower-privileged users who have been granted dashboard sharing access (such as Editors) to modify a site-wide Site Kit by Google WordPress plugin before 1.176.0 setting that should only be modifiable by administrators.
AnalysisAI
Insufficient REST API authorization in the Site Kit by Google WordPress plugin before version 1.176.0 permits users with dashboard sharing access - such as those granted the Editor role - to write to a site-wide settings endpoint that should be restricted to administrators. The integrity impact is confined to plugin-level configuration, but the flaw is significant because dashboard sharing is commonly granted to non-admin contributors on multi-author sites. A publicly available proof-of-concept exists per WPScan; exploitation probability remains very low (EPSS 0.13%, 3rd percentile) and the vulnerability is not listed in the CISA KEV catalog.
Technical ContextAI
Site Kit by Google is the official Google-published WordPress plugin that connects a site to Google services including Search Console, Analytics, AdSense, and PageSpeed Insights. It exposes REST API endpoints for administrative operations. The flaw is a missing or insufficient capability check on a write endpoint - conceptually aligned with CWE-862 (Missing Authorization) - where the plugin fails to enforce that only users with the WordPress 'manage_options' or equivalent administrator capability can modify the site-wide setting in question. CWE is listed as N/A in the NVD entry, but the description clearly indicates an authorization enforcement gap on a REST route. The affected CPE is cpe:2.3:a:unknown:site_kit_by_google:*:*:*:*:*:*:*:* covering all versions below 1.176.0.
RemediationAI
Update the Site Kit by Google WordPress plugin to version 1.176.0 or later; this is the vendor-released patch confirmed by WPScan (https://wpscan.com/vulnerability/824a5c04-c7d6-4286-a499-48452db4d002/). If an immediate upgrade is not feasible, the most effective compensating control is to revoke or minimize dashboard sharing grants: remove Editor-level dashboard sharing access from any untrusted users until the patch is applied, since the vulnerability is only exploitable by users who have been explicitly granted that access. Disabling the plugin entirely is a more disruptive alternative that fully removes the attack surface but breaks Google service integrations. There is no known server-side WAF rule that can reliably block this specific REST endpoint misuse without also blocking legitimate admin traffic to the same endpoint.
