$250 | Stored XSS via SVG Upload on a Private HackerOne Program! (Bug Bounty)

In this video, I’m sharing a real-world Stored XSS vulnerability I discovered through an SVG file upload functionality in a private HackerOne bug bounty program. I’ll walk through how the vulnerability was identified, how the uploaded SVG was processed, how the payload persisted, and how the XSS was triggered. I’ll also explain the impact and the responsible disclosure process through HackerOne. This video is focused on bug bounty methodology, web security testing, and educational purposes. ⚠️ Disclaimer: This video is intended strictly for educational and ethical cybersecurity purposes. All testing shown was performed on an authorized bug bounty target where security research was permitted. Do not attempt to test or exploit systems without proper authorization. Always follow the program’s scope, rules, and responsible disclosure guidelines. #BugBounty #HackerOne #StoredXSS #XSS #SVGUpload #WebSecurity #CyberSecurity #EthicalHacking #BugBountyHunter #ApplicationSecurity #Pentesting #SecurityResearch #InfoSec
