CVE & Vulnerability Research
700+ vulnerabilities discovered and responsibly disclosed. #7 worldwide and #1 in France on the Wordfence all-time researcher ranking.
Focused, evidence-backed security research
I work as a CVE researcher and WordPress security researcher, uncovering real, high-impact vulnerabilities in WordPress plugins and reporting them through coordinated disclosure. Every finding below is documented in an authoritative, third-party advisory — this is verifiable research, not a list of identifiers.
The bulk of my work is credited on the Wordfence and Patchstack platforms, where I currently rank #7 worldwide all-time on Wordfence and among the top 8 on Patchstack — and I am #1 in France, the French researcher with the most CVEs.
Wordfence lists 712 all-time discoveries credited to me — 700 unique CVEs. The chart below shows the severity breakdown, including 26 Critical and 75 High findings, with CVSS scores from the published advisories:

Vulnerability classes
My research regularly covers the following classes of vulnerability, with a particular focus on access-control and authentication failures that lead to full compromise:
- PHP Object Injection
- SQL Injection
- Remote Code Execution
- Privilege Escalation
- Broken Access Control
- Cross-Site Scripting
- Cross-Site Request Forgery
- Sensitive Data Exposure

Methodology
- Manual source-code auditing — reading plugin code rather than relying only on automated scanning.
- White-box research — analysing data flows, capability checks and nonce handling to find broken access control and privilege escalation.
- Responsible disclosure — coordinating with vendors and platforms so that patches ship before public details.
