Last month in October 2025, the Wordfence Bug Bounty Program received 486 vulnerability submissions from our growing community of security researchers working to improve the overall security posture of the WordPress ecosystem. These submissions are reviewed, triaged, and processed by the Wordfence Threat Intelligence team, with validated vulnerabilities responsibly disclosed to vendors, often through the Wordfence Vulnerability Management Portal, and protected through the Wordfence Firewall where appropriate.
Our mission with the Wordfence Bug Bounty Program is to engage the broader security community in identifying and responsibly disclosing vulnerabilities in WordPress plugins and themes, so we can get them patched before attackers discover them. This collaborative effort enables Wordfence to accelerate patch adoption, provide early protection to millions of websites, and ensure that high-quality vulnerability intelligence reaches the WordPress ecosystem as efficiently as possible. It also ensures that we are able to remediate vulnerabilities before attackers are able to discover them and start exploiting them. That is why we reward researchers for valid submissions, and why we remain committed to processing every report with transparency, accuracy, and urgency.

📊 Program Submission Highlights – October 2025
The Wordfence Bug Bounty Program is designed for momentum: rapid triage of critical issues, clear feedback, and fast, fair rewards. Each submission moves through our standardized workflow of validation, vendor coordination, patch verification, and firewall coverage where applicable, so research translates into real-world protection quickly.
🛡️ Real-Time Protection Impact
Every vulnerability disclosed through this program is a threat you don’t have to face blindly. Our researchers uncover and report vulnerabilities before they can be exploited, and Wordfence Premium, Care and Response users get protection in real-time through our firewall. Free users are protected in 30 days.
Behind the numbers is meaningful impact for site owners. The issues surfaced here inform new firewall rules, strengthen our detection logic, and help vendors ship safer releases. If you’re new to bounty hunting, this is a great place to start: we publish scope clearly, pay promptly, and credit the work that keeps WordPress secure.

🔍 WordPress Software Vulnerability Submission Insights – October 2025
This section breaks down how reports map to our program outcomes. What’s in scope, what isn’t, and where the highest security impact typically sits. We highlight the most common in-scope vulnerability classes and the categories that yielded the largest rewards so researchers can focus their efforts where they matter most.
Authentication level and exploit preconditions drive risk and reward through our program. Unauthenticated and low-privilege paths tend to have outsized impact because they scale to more real-world compromise.

🔦 Critical WordPress Software Vulnerability Highlights – October 2025
These case studies spotlight high-impact vulnerabilities uncovered through the program, why they matter, and how quickly protection rolled out. We share technical detail to help researchers learn, vendors harden code, and users understand why timely updates aren’t optional.
If you maintain a site, update to the patched versions listed and ensure Wordfence is active so you benefit from new firewall coverage as it ships. If you’re a researcher, use these write-ups to inform your hunt: patterns repeat, and past root causes often reappear in adjacent code.
🚨 Attackers Actively Exploiting Critical Vulnerability in Service Finder Bookings Plugin
Service Finder Bookings <= 6.0 – Authentication Bypass via User Switch Cookie
Foxyyy
$1,002.00
The Service Finder Bookings plugin for WordPress is vulnerable to privilege escalation via authentication bypass in all versions up to, and including, 6.0. This is due to the plugin not properly validating a user’s cookie value prior to logging them in through the service_finder_switch_back() function. This makes it possible for unauthenticated attackers to login as any user including admins.
🚨 4,000,000 WordPress Sites Affected by Arbitrary File Read Vulnerability in Slider Revolution WordPress Plugin
Slider Revolution <= 6.7.36 – Authenticated (Contributor+) Arbitrary File Read via ‘used_svg’ and ‘used_images’
stealthcopter
$656.00
The Slider Revolution plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 6.7.36 via the ‘used_svg’ and ‘used_images’ parameters. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
🚨 100,000 WordPress Sites Affected by Arbitrary File Read Vulnerability in Anti-Malware Security and Brute-Force Firewall WordPress Plugin
Anti-Malware Security and Brute-Force Firewall <= 4.23.81 – Missing Authorization to Authenticated (Subscriber+) Arbitrary File Read
Dmitrii Ignatyev
$960.00
The Anti-Malware Security and Brute-Force Firewall plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 4.23.81 due to a missing capability check combined with an information exposure in several GOTMLS_* AJAX actions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
🚨 Attackers Actively Exploiting Critical Vulnerability in WP Freeio Plugin
WP Freeio <= 1.2.21 – Unauthenticated Privilege Escalation
Foxyyy
$358.00
The WP Freeio plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.2.21. This is due to the process_register() function not restricting what user roles a user can register with. This makes it possible for unauthenticated attackers to supply the ‘administrator’ role during registration and gain administrator access to the site.
📝 Conclusion
WordPress thrives when researchers, vendors, hosts, and site owners pull in the same direction. By funding high-quality research, coordinating responsible disclosure, and shipping firewall rules at scale, Wordfence turns findings into protection for millions of sites.
If you’re a researcher, join the program and submit your next report. If you’re a site owner, update early and often, and run Wordfence to stay ahead of emerging threats. If you’re a vendor, sign up for the vulnerability management portal to receive real-time notifications when new vulnerabilities are reported in your software. Together, we make the ecosystem safer every month.
