WordPress pre-auth login XSS can chain to full server takeover

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.

Check
Update WordPress to the patched release across every site, including forgotten and staging installs, and put a web application firewall in front of internet-facing sites.
Affected
All WordPress sites on versions before the fix (CVE-2026-64638); an unauthenticated attacker can run script in the login page, and luring an administrator to a crafted page can chain to code execution.
Fix
Apply the WordPress update, confirm automatic updates ran, use a web application firewall, and remind administrators to avoid unexpected links, since the chain to code execution runs through an admin's browser.

Public exploits released for WordPress core flaws that give anonymous code execution

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.

Check
Confirm every WordPress site you run, including forgotten and staging instances, is on 6.9.5 or 7.0.2 or later, then check logs and web directories for web shells.
Affected
Any site on WordPress 6.9.0 to 6.9.4 or 7.0.0 to 7.0.1 (CVE-2026-63030, CVE-2026-60137); no plugins, login, or user interaction are needed, and working exploits are public.
Fix
Update to WordPress 6.9.5 or 7.0.2, confirm auto-updates applied, put a web application firewall in front of exposed sites, and treat unpatched internet-facing installs as potentially compromised.

Australia warns of a global campaign hitting websites through known CMS flaws

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.

Check
Inventory your public websites and their CMS platforms, themes, and plugins, apply outstanding security updates, remove unused components, and review access and network logs and existing accounts for signs of compromise.
Affected
Organizations running internet-facing CMS platforms like WordPress, Joomla, or Craft CMS with unpatched plugins; attackers automatically exploit known flaws to plant web shells, disproportionately hitting small and medium-sized businesses.
Fix
Patch CMS software and plugins promptly, enable automatic updates where possible, make web directories read-only where feasible, restrict access to sensitive directories, and restore from a known-clean backup if compromise is found.

Exposed server reveals crew that backdoored thousands of WordPress sites for resale

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.

Check
Update WordPress and Joomla plugins, especially the Breeze caching plugin and Joomla's JCE editor, and hunt for webshells with suspicious names and fake kernel-worker processes that indicate a backdoor.
Affected
Organizations running WordPress or Joomla sites with outdated, vulnerable plugins; the crew automatically exploits known flaws to plant backdoors, then sells that access, making even low-profile sites worthwhile footholds.
Fix
Keep plugins patched on a regular cadence, put a web application firewall in front of anything you cannot patch immediately, scan for known webshell indicators, and rotate credentials on exposed configuration servers.

Hackers mass-exploit Gravity SMTP WordPress flaw to steal email API keys

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.

Check
Identify WordPress sites running Gravity SMTP at version 2.1.4 or earlier, and review web server access logs for requests to the /wp-json/gravitysmtp/v1/tests/mock-data endpoint, which indicate attempted or successful data exposure.
Affected
WordPress sites running Gravity SMTP through 2.1.4 with email integrations configured (CVE-2026-4020); exposed API keys and OAuth tokens let attackers abuse connected email services and map the site for follow-on attacks.
Fix
Update Gravity SMTP to 2.1.5 or later, then assume compromise: rotate all API keys, secrets, and OAuth tokens set in the plugin's email connectors, and block the published attacker IPs.

Hacked WordPress plugin updates push credential-stealing backdoor to paying sites

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.

Check
Check whether your WordPress sites run ShapedPlugin's Product Slider Pro, Real Testimonials Pro, or Smart Post Show Pro, and look for unfamiliar plugins impersonating WooCommerce components and new admin or file-write activity.
Affected
WordPress sites that updated the paid plugins Product Slider Pro (before 3.5.4), Real Testimonials Pro 3.2.5, or Smart Post Show Pro (before 4.0.2) between May 21 and the fix (tracked as CVE-2026-10735).
Fix
Update the affected ShapedPlugin products to fixed versions, remove any rogue WooCommerce-impersonating plugin, rotate all site and admin credentials, and scan the site for web shells and unauthorized file changes.

WordPress plugin supply-chain attack backdoors sites via Awesome Motive CDN

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.

Check
If your site runs OptinMonster, TrustPulse, or PushEngage, check for rogue admin accounts like developer_api1 or dev_xxxxxx and inspect wp-content/plugins for hidden backdoor plugins.
Affected
WordPress sites running OptinMonster, TrustPulse, or PushEngage where an administrator was logged in during the June 12 to 14 injection window; other Awesome Motive plugins should be treated cautiously.
Fix
Remove rogue admin accounts and backdoor plugins, then rotate administrator passwords, API keys, database credentials, and WordPress security salts. Update affected plugins and scan the site for further tampering.

Critical Everest Forms WordPress plugin flaw exploited to create rogue admins

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.

Check
Inventory WordPress sites for Everest Forms Pro and confirm version 1.9.13 or later. Audit for a rogue admin named 'diksimarina' and review forms using the Complex Calculation feature.
Affected
Everest Forms Pro versions up to 1.9.12 using the Complex Calculation feature. Unauthenticated attackers inject PHP via any string-type field into an unescaped eval(). Exploited since April 13.
Fix
Upgrade Everest Forms Pro to 1.9.13 immediately. Remove rogue admins (e.g. 'diksimarina'), rotate admin credentials, and audit for web shells. Block the published attacker IPs.

Critical Kirki WordPress flaw CVE-2026-8206 exploited to hijack admin accounts via password-reset redirect - 500,000 installs, 222+ attacks blocked

Hackers are exploiting CVE-2026-8206, a critical privilege-escalation flaw in the Kirki - Freeform Page Builder WordPress plugin, to take over any account including administrators. Defiant's Wordfence blocked over 222 attempts against customers in 24 hours. The plugin is active on more than 500,000 sites; the bug was introduced in version 6.0.0 and affects up to 6.0.6 (nearly 40% of the userbase). It stems from a custom REST password-reset endpoint that accepts an arbitrary email: when a username is supplied, the plugin sends a valid reset link to the attacker-controlled address instead of the owner's. The vendor fixed it in 6.0.7 on May 18; admins should upgrade or disable immediately.

Check
Inventory WordPress sites for the Kirki plugin and confirm version. Audit user accounts and password-reset logs for reset links sent to unfamiliar email addresses since version 6.0.0 deployment.
Affected
Kirki - Freeform Page Builder versions 6.0.0 through 6.0.6 (nearly 40% of 500,000+ installs). The REST password-reset endpoint sends valid reset links to attacker-supplied email addresses for any user.
Fix
Upgrade Kirki to 6.0.7 or disable the plugin immediately. Remove unauthorized admin accounts, rotate all admin credentials, and audit for web shells, malicious plugins, and backdoors.

WordPress malware hides C2 in Steam profile comments using invisible Unicode - ~1,980 sites infected since July 2025

GoDaddy has documented a WordPress malware campaign that hides command-and-control data inside Steam Community profile comments, abusing Valve's platform to avoid running separate C2 infrastructure and evade detection. Around 1,980 WordPress sites have been infected since July 2025. The first-stage malware loads a Steam profile on each page view and extracts text from benign-looking comments that conceal a payload encoded with six invisible Unicode characters such as zero-width joiners. The decoder maps the invisible characters to bytes, reconstructs a URL to hello-mywordl[.]info, and injects JavaScript disguised as a legitimate library into every frontend page. The final stage is a backdoor that responds to POST requests carrying a specific authentication cookie.

Check
Audit WordPress sites for injected first-stage loaders calling Steam Community profiles and frontend JavaScript from hello-mywordl[.]info. Check admin accounts, FTP/SFTP credentials, and theme/plugin integrity.
Affected
WordPress sites compromised via stolen admin logins, weak FTP/SFTP credentials, or vulnerable themes/plugins. ~1,980 sites infected since July 2025 using Steam profile comments as a covert C2 channel.
Fix
Remove injected scripts and the POST-triggered backdoor. Rotate all WordPress admin and FTP/SFTP credentials. Patch themes/plugins. Block hello-mywordl[.]info and monitor web-server requests to Steam profile pages.
