Following the coordinated and responsible vulnerability disclosure guidelines of the **[ISO 29147]()** standard, Open Bug Bounty has:
a. verified the vulnerability and confirmed its existence;
b. notified the website operator about its existence.
Technical details of the vulnerability are currently hidden (“On Hold”) to give the website operator/owner sufficient time to patch the vulnerability without putting any of its systems or users at risk. Once patched, vulnerability details can be publicly disclosed by the researcher in at least 30 days since the submission. If for a reason the vulnerability remains unpatched, the researcher may disclose vulnerability details only after 90 days since the submission.
