A critical flaw in Forminator Forms, a WordPress plugin with more than 600,000 installations, lets unauthenticated attackers upload executable PHP files and take over a site. Tracked as CVE-2026-15748 and scored 9.8, the bug chains weaknesses in the plugin's upload handling: an attacker smuggles a forged record through a Select field that declares itself a file upload, then slips a PHP file past a blocklist that only checks exact extensions. Exploitation requires a form with both a file upload field and a select field, and it affects all versions up to 1.56.1. Because it needs no authentication, automated scanners can hunt for vulnerable sites at scale.
Researchers at Wordfence found that attackers compromised the upstream infrastructure of BdThemes, a popular WordPress plugin vendor, and poisoned a remote JSON feed that its plugins fetch to show promotional banners in the admin dashboard. Because the malicious code lives in that feed rather than in the plugin source, no plugin update was needed and nothing changed on disk. The injected script runs in every logged-in administrator's browser, creates hidden rogue admin accounts through the site's own interface, and installs a fake plugin containing a web shell for persistence. Seven plugins including Element Pack and Prime Slider were affected, and the flaw sat unnoticed for about five months.
WordPress patched a pre-authentication reflected cross-site scripting flaw in the login screen that researchers showed can chain into PHP code execution and full server takeover, naming the chain XSS2Shell. Tracked as CVE-2026-64638 and scored 8.9, the cross-site scripting bug affects all WordPress versions and needs no login to trigger. On its own it runs script in a visitor's browser, but when a logged-in administrator is lured to an attacker-controlled page, the chain can reach code execution on the server. Because WordPress runs a large share of the web, a flaw affecting every version and needing no authentication has broad reach.
Public exploit code is now available for wp2shell, a pair of WordPress core flaws that chain into pre-authentication remote code execution against a stock site with no plugins installed. CVE-2026-63030 is a route confusion bug in the REST API batch endpoint, which has shipped enabled by default since 2020, and CVE-2026-60137 is a SQL injection in the author parameter handling of WP_Query. Chained, an anonymous HTTP request can run code on the server. The chain affects WordPress 6.9.0 through 6.9.4 and 7.0.0 through 7.0.1, fixed in 6.9.5 and 7.0.2, and WordPress enabled forced automatic updates given the severity.
Australia's Cyber Security Centre has warned of a large-scale global campaign in which attackers scan websites and exploit known vulnerabilities in content management systems and their plugins to plant web shells. The affected software spans WordPress, Joomla, Craft CMS, and others, with the flaws typically allowing unauthenticated file upload, remote code execution, or server-side request forgery. Once a web shell is installed, attackers can take a site offline, deface it, steal data stored on the server, or pivot deeper into the network. Many small and medium-sized businesses have already been hit, and the agency notes the campaign may be accelerated by AI, which helps attackers scale exploitation of newly disclosed flaws.
A cybercrime group left its own server exposed on the internet for weeks, revealing a mass website-hacking operation that researchers at SOCRadar now track as WP-SHELLSTORM. The crew breaks into sites at scale, plants hidden backdoors, and resells the access to other criminals. Rather than using zero-days, it automated attacks against 27 known vulnerabilities in outdated WordPress and Joomla plugins; a single flaw in the Breeze caching plugin accounted for over 17,000 backdoored sites. Target lists named more than 1.4 million domains, with roughly 25,000 confirmed compromised. The same server also revealed an earlier campaign that stole cloud credentials and database passwords from exposed configuration servers.
Attackers are mass-exploiting a flaw in Gravity SMTP, a WordPress email plugin installed on about 100,000 sites, to harvest credentials without any login. The bug (CVE-2026-4020) leaves a REST API endpoint with a permission check that always passes, so a single unauthenticated request returns a 365 KB system report containing API keys, secrets, and OAuth tokens for connected email services like Amazon SES, Mailjet, and Zoho, plus detailed software-stack information. Wordfence has blocked more than 17 million attempts, with activity spiking around June 6 and 7. A patch shipped in version 2.1.5, but updating does not revoke keys attackers may have already grabbed.
Attackers compromised the build pipeline of ShapedPlugin, a WordPress plugin maker, and slipped malware into legitimate updates delivered to paying customers through the vendor's own update system. The tainted releases install a fake plugin that impersonates WooCommerce components, steals site credentials, and gives attackers the ability to write files remotely. Three paid plugins are affected: Product Slider Pro for WooCommerce, Real Testimonials Pro, and Smart Post Show Pro. The backdoor was injected into Pro builds on May 21, with the first customer reports on June 10. Versions on WordPress.org stayed clean, pointing to a compromise of the vendor's release infrastructure rather than the plugins themselves.
Attackers compromised the content-delivery network of Awesome Motive, one of the biggest WordPress plugin makers, and injected malicious JavaScript into files served for OptinMonster, TrustPulse, and PushEngage, plugins running on more than 1.2 million sites. Discovered by Sansec, the code only triggered when a logged-in WordPress administrator viewed an affected site, at which point it stole authentication tokens, created a hidden rogue admin account, and installed a self-concealing backdoor plugin that exposed a web shell. The bad files were served on June 12 to 14. Awesome Motive says attackers stole a CDN API key after breaching its marketing site, and has since rotated credentials.
Wordfence reports active exploitation of CVE-2026-3300 (CVSS 9.8), a remote code execution flaw in the Everest Forms Pro WordPress plugin (about 4,000 active installations) affecting all versions up to 1.9.12. The Calculation Addon's process_filter() function concatenates user-submitted form-field values into a PHP string and passes it to eval() without proper escaping; sanitize_text_field() does not escape single quotes, so unauthenticated attackers can inject and run arbitrary PHP by submitting a crafted value in any string-type field when a form uses the Complex Calculation feature. Exploitation began April 13; Wordfence has blocked 29,300+ attempts. The common payload creates a rogue admin named 'diksimarina.' Patch 1.9.13 shipped March 18.
