Auth bypass in Keywordrush Content Egg – Affiliate Product Importer & Price Comparison
CVE-2026-119751
Content Egg plugin for WordPress before 12.1.0 contains a broken access control vulnerability that allows unauthenticated attackers to retrieve Content Egg product data from unpublished posts by calling the REST route POST /wp-json/content-egg/v1/render-blocks, whose permission_check() improperly returns true when no X-WP-Nonce header is supplied. Attackers can supply the post_id and module id of a draft, pending, scheduled, or private post to handle_render(), which lacks a publish-status check, to disclose product titles, destination and affiliate URLs, merchant or domain information, and descriptions.
