Rules

What the policy asks of you, and the bug types it won't reward, quoted from Leaseweb's policy. "We" in these lines means the program, not this site.

While testing

  • Notify us as soon as possible upon discovery of a potential security issue.
  • Provide us a reasonable amount of time to resolve the issue before any disclosure to the public or a third -party.
  • Only use official communication channels.
  • No unauthorized impersonation: any unauthorized attempts to socially engineer another party through impersonation of a Leaseweb employee, another hacker, or a security team will not be tolerated.
  • Solely use your created accounts and not access data of other users
  • Not publicly disclose the vulnerability prior to our resolution

  • Any physical attempts against Leaseweb property or data centers

  • Report from automated tools and scans
  • Bugs in 3rd party software
  • X-Frame-Options or CSP equivalent related
  • Missing cookie flags on non-sensitive cookies
