Description
Summary:
Hi Team!
On Team object the parameter "i_cannot_create_jira_webhook_reasons" is not NULL and gets the following default states when called for all programs ["CANNOT_VIEW","FEATURE_GATED","PROGRAM_PERMISSION_REQUIRED"]
If a Company Program runs a Private Program or a Public On the "FEATURE_GATED" is missing (Since the feature is not gated anymore) and therefore an attacker can find if a Company is running a private program
POC
Company ██████ (not runnig private gives "i_cannot_create_jira_webhook_reasons":["CANNOT_VIEW","FEATURE_GATED","PROGRAM_PERMISSION_REQUIRED"]
Company █████████ (running private) gives "i_cannot_create_jira_webhook_reasons":["CANNOT_VIEW","PROGRAM_PERMISSION_REQUIRED"]
Even Company HackerOne (running public) gives "i_cannot_create_jira_webhook_reasons":["CANNOT_VIEW","PROGRAM_PERMISSION_REQUIRED"]
All private programs and public has an overriden "FEATURE_GATED" so you get the idea
Solutiion
NULL the value maybe
PS: Thanks to @jobert who encouraged me to search deeper after the #347383 duplicate!
Thanks

Impact
