  • Do provide Proof-of-Concept or sufficient information to enable reproduction of the vulnerability, so that it can be verified, reproduced, and possible remedies identified. Generally, identification of the vulnerable target, a description of the vulnerability and operations carried out to exploit the vulnerability are sufficient, but more details and information might be required in the case of complex vulnerabilities.

  • Resolve all submitted reports as quickly as possible.

  • Vodafone do not operate a bug bounty or hall of fame programme.

  • Vulnerabilities only affecting users of outdated or unpatched browsers [Less than 2 stable versions behind the latest released stable version]

  • Software version disclosure / Banner identification issues / Descriptive error messages or headers (e.g. stack traces, application or server errors).

  • Tabnabbing

  • Open redirect - unless an additional security impact can be demonstrated

  • Issues that require unlikely user interaction
