HackerOne CVEs TryHackMe


🚀 About Me

Offensive Security Researcher who reads other people's source code for a living, and occasionally gets a CVE for it.

  • 10 published CVEs across Gitea, SuiteCRM, and ChamiloLMS — spanning RCE-enabling gate bypass, blind SSRF, cross-repo disclosure, privilege escalation, and account takeover.
  • Ranked Top 100 security researchers in India — HackerOne (2025), Top 5% globally on TryHackMe.
  • 100+ valid vulnerabilities responsibly disclosed across Google, Sony, Discourse, SupaBase,NASA, United Nations, US Department of Defence, British Airways, Netherlands Government, Stanford University, Starbucks, Groww, LeetCode, and more.
  • Building Sentryd — an AI-assisted supply-chain scanner that catches malicious-by-design packages signature tools miss, and turns every finding into a deployable Sigma/KQL/YARA rule.
  • Competed in national-level VAPT exercises (Pentathon '24, '25) run by the Government of India — realistic Web, API, and OT attack scenarios.

🔍 What I Do

🎯 Bug Hunting

Reported 100+ valid vulnerabilities across HackerOne - Public/Private programs — RCE, SSRF, IDOR, Auth Bypass, Privilege Escalation, BFLA, and PII exposure chains. Every report ships with full PoC, CVSS scoring, and MITRE ATT&CK mapping.

🛠 Security Research & Tooling

Building custom exploitation and automation tooling in Python and Bash — rate-limit bypass techniques, web cache deception detection, and OSINT/recon pipelines that cut manual triage time.

🧩 Open Source

Contributor to OWASP Cornucopia across 6 releases (v2.6.14 → v3.1.0) — shipped a Swagger API, implemented CRE API Companion Edition, fixed SSR routing failures, and hardened schema-level input validation in production.


🌟 Highlighted Projects

Project Description
🛡️ Sentryd AI-assisted supply-chain scanner — catches malicious-by-design packages (typosquats, dependency confusion, credential-harvesting install hooks) that signature-based tools miss. Generates validated Sigma/KQL/Falco/YARA rules, MITRE-tagged, with SARIF + CycloneDX SBOM output.
🎭 Deceptor Automated detection and exploitation of web cache deception vulnerabilities.
🔭 Approach End-to-end automated recon pipeline — subdomain enumeration, passive OSINT, AI-driven vulnerability triage.
🧅 Tornet Granted Research tool for enumerating onion URLs over the Tor network.
🕵️ Xpose Research-focused deanonymization tool for investigating illegal dark web operations.

💭 A quote I live by

"The best vulnerability report isn't the one with the highest CVSS score — it's the one a developer can read once and immediately understand how to fix."
