HackerOne Delays IBB Payouts To Researcher

Jakub Ciolek reported two high-severity denial-of-service bugs in Argo CD last fall via HackerOne's Internet Bug Bounty; both were assigned CVE-2025-59538 and CVE-2025-59531 and fixed on Sept. 30, 2025. HackerOne did not respond for months, later citing a temporary operational backlog and saying reward payouts are pending and expected by end of Q1 2026. The communication gap undermines confidence in the IBB model.
