Technical summary

The Page and Post Restriction plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to and including 1.4.0. The plugin's REST guards — papr_restrict_page_post_rest_api() and the the_posts filter registered by papr_filter_posts() — source their restricted-ID list exclusively from papr_get_restricted_posts_id(), which only reads per-page metabox options and never consults global toggles for making all Pages and Posts private.

Defensive priority

High priority due to high CVSS score and potential for widespread exploitation

Recommended defensive actions

• Upgrade to a patched version of the Page and Post Restriction plugin
• Review and adjust the plugin's configuration to ensure proper access controls
• Monitor for potential exploitation attempts
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

Evidence from the CVE record and source item indicates that the Page and Post Restriction plugin for WordPress is vulnerable to Sensitive Information Exposure. The plugin's REST guards do not properly consider global toggles for making all Pages and Posts private, allowing unauthenticated access to published content.
