Reporting a Vulnerability

We're extremely grateful for security researchers and users that report vulnerabilities to the userver Open Source Community. All reports are thoroughly investigated by developers.

🐙 userver is the part of the "The Yandex Bug Bounty" program. To report a potential vulnerability or weakness in userver please send the details about it to https://yandex.com/bugbounty/i/report/.

When Should I Report a Vulnerability?

• You think you discovered a potential security vulnerability in userver
• You are unsure how a vulnerability affects userver

When Should I NOT Report a Vulnerability?

• You need help tuning userver components for security
• You need help applying security related updates
• Your issue is not security related

Security Vulnerability Response

Each report is acknowledged and analyzed by userver maintainers within 5 working days. As the security issue moves from triage, to identified fix, to release planning we will keep the reporter updated.

Public Disclosure Timing

A public disclosure date is negotiated by the userver maintainers and the bug submitter. We prefer to fully disclose the bug as soon as possible once a user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate to 90 days. For a vulnerability with a straightforward mitigation, we expect report date to disclosure date to be on the order of 7 days.
