At Xistyl Private Limited (including its affiliates) (hereinafter referred to as ‘Xistyl’), we appreciate and encourage security researchers to contact us to report potential vulnerabilities identified in any product, system, or asset belonging to us.

In support, we have established a Responsible Disclosure Policy, also called a Vulnerability Disclosure Policy. This policy is designed to create a clear communication path around reporting and disclosing exploitable vulnerabilities in our systems.

We may modify and revise this policy at our sole discretion as we move forward into the future; please continue to check here for updates.

Rules of Engagement

  1. Researchers submitting a vulnerability to Xistyl agree to be bound by the terms of the Responsible Disclosure Policy (hereinafter referred to as the ‘Terms’).

  2. What is in scope and out of scope when discovering vulnerabilities is clearly mentioned and specified in the sections below.

  3. Researchers shall ensure that they do not engage in privacy violations, degradation of user experience, disruption to production systems, and destruction or manipulation of data.

  4. Researchers should only use/exploit to the extent necessary to confirm a vulnerability. Researchers should not use or exploit to compromise or exfiltrate data, establish command line access and/or persistence, or use/exploit to “pivot” to other systems.

  5. Once a researcher establishes that a vulnerability exists, or encounters any sensitive data, the researcher shall stop any further testing and notify Xistyl immediately. Researchers are required to keep any information about discovered vulnerabilities confidential even after submitting the vulnerability report.

  6. Xistyl discourages violation of applicable laws and breach of any agreements in order to discover vulnerabilities and reserves the right to pursue legal action when the terms of this policy are violated or when testing is performed outside the scope of this policy. The decision made by our security team regarding validity, severity & impact of a vulnerability will be considered final and cannot be contested.

  7. Xistyl may share your vulnerability reports with any affected partners, vendors or open source projects.

  2. If the identified vulnerability can be used to potentially extract information of our customers or systems, or impair our systems' ability to function normally, then please refrain from actually exploiting such a vulnerability. This is absolutely necessary for us to consider your disclosure a responsible one.

  3. While we appreciate the inputs of researchers, we may take legal recourse if the identified vulnerabilities are exploited for unlawful gains or getting access to restricted customer or system information, or impairing our systems.
