+### Disclosure Terms
+
+The Flowise team believes that transparency is important and public bug bounty reports are a valuable source of knowledge for bug bounty researchers. However, the Flowise team may have legitimate reasons not to disclose vulnerabilities. 
 
--   Do not publicly disclose vulnerabilities until we have assessed, resolved, and notified affected users.
--   If you plan to present your research (e.g., at a conference or in a blog), share a draft with us at least **30 days in advance** for review.
--   Avoid including:
-    -   Data from any Flowise customer projects
-    -   Flowise user/customer information
-    -   Details about Flowise employees, contractors, or partners
+Do not discuss or disclose vulnerability information without prior written consent. If you plan on presenting your research, please share a draft with us at least 45 days in advance for review. Avoid including:
+-   Data from any Flowise customer projects
+-   Flowise user/customer information
+-   Details about Flowise employees, contractors, or partners

+We will validate submissions within the below timelines.
+| Vulnerability Severity | Time to Validate |
+| ---------------------- | ---------------- |
+| Critical | 5 business days |
+| High | 5 business days |
+| Medium | 15 business days |
+| Low | 15 business days |

+
+### Public Disclosure Timeline
