TL;DR: Duplicate and repeat bug bounty submissions are usually a signal that a vulnerability was either not fully fixed or later reintroduced, and Intigriti reports that an average of 3% of reported issues have resurfaced, with some instances reaching 8%. The governance problem is not just payout duplication but weak retesting discipline and release validation that allow the same flaw to reappear.
Editorial analysis by NHI Mgmt Group, based on content published by INTIGRITI: “Preventing the growing costs of repeat and duplicate bug bounty submissions”.
Key questions
Q: What breaks when a bug bounty issue is marked fixed before retesting?
A: The control that breaks is assurance.
Q: Why do repeat bug bounty submissions matter more than simple duplicates?
A: Repeat submissions mean a vulnerability was believed fixed and then resurfaced, which points to a remediation or release-validation failure rather than normal report overlap.
Q: How can security teams tell whether duplicate reports indicate a recurring flaw?
A: They should compare the underlying root cause, affected paths, and fix logic.
Practitioner guidance
- Strengthen retesting gates for closed findings Require retest or equivalent validation before a high-risk bug bounty issue is marked fully resolved, especially where authentication, access control, or session logic was involved.
- Map repeated reports to root causes Group duplicate and repeat submissions by underlying defect, not by ticket ID, so engineering sees whether the same code path, endpoint, or release pattern is responsible.
- Add post-deployment verification to release workflows Verify that patched vulnerabilities remain fixed after deployment and after subsequent releases, because recurrence often happens when a later change reopens the same condition.
Bottom line: Recurring bug bounty reports usually mean the same weakness was not fully removed or later came back through a new release path.

Duplicate findings are a remediation quality signal, not a reporting nuisance. When the same issue resurfaces, the deeper question is whether the fix ever truly removed the root cause or only cleared the ticket. That makes duplicate volume a useful indicator of control weakness in the change and validation process. Practitioners should read duplication patterns as evidence of unresolved governance, not just researcher overlap.
A question worth separating out:
Q: When should programmes require extra accountability for reopened vulnerabilities?
A: Programmes should escalate accountability when the same vulnerability returns after closure, especially in fast-release environments or in controls affecting identity and access. Reopenings show that remediation ownership was not durable across release and validation stages. The question is not who found it twice, but why the organisation could not keep it closed.
