Aug 24, 2026BetterLinks – Link Shortener, Link Cloaking, Redirects, Affiliate Link Manager & MCP: Authorization bypassCVE-2026-19801 · WordPress plugins & themes · reported by WordfenceMedium 4.3
The BetterLinks – Link Shortener, Link Cloaking, Redirects, Affiliate Link Manager & MCP plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.1.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to create arbitrary BetterLinks short URLs with attacker-controlled slugs and redirect destinations, enabling phishing and SEO abuse. Exploitation requires the Fluent Boards companion plugin to be installed and active (so that the FLUENT_BOARDS constant is defined), and is further facilitated by the betterlinks_admin_nonce nonce being emitted on every frontend page via wp_localize_script, making it accessible to any authenticated user.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
