Last month in August 2025, the Wordfence Bug Bounty Program received 438 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 – a free service for all WordPress vendors, 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 work with vendors to 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 – August 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 – August 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. Use these insights to prioritize your testing strategy and maximize both security value and bounty potential.

Critical WordPress Software Vulnerability Highlights – August 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.
Dokan Pro Critical Privilege Escalation
Dokan Pro <= 4.0.5 – Authenticated (Vendor+) Privilege Escalation
Foxyyy
$966.00
The Dokan Pro plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 4.0.5. This is due to the plugin not properly validating a user’s identity prior to updating their password during a staff password reset. This makes it possible for authenticated attackers, with vendor-level access and above, to elevate their privilege to the level of a staff member and then change arbitrary user passwords, including those of administrators in order to gain access to their accounts. By default, the plugin allows customers to become vendors.

UI Core Elements Arbitrary File Read
UiCore Elements <= 1.3.0 – Missing Authorization to Unauthenticated Arbitrary File Read
mikemyers
$617
The UiCore Elements – Free Elementor widgets and templates plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 1.3.0 via the prepare_template() function due to a missing capability check and insufficient controls on the filename specified. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.
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 WordPress ecosystem safer.
