Benjamin Marwell commented on SHIRO-808:
----------------------------------------

Hi [~Palak-137] and [~k4n5hao],

the next time you discover a security-relevant issue, please obey Apache’s 
security policy:

[https://www.apache.org/security/]
{quote}We strongly encourage the reporting of potential security 
vulnerabilities to one of our private security mailing lists first, before 
disclosing them in a public forum.
{quote}
We have an appropriate mailing list for this: 
[[email protected]|mailto:[email protected]]

Thank you!

 

[~Palak-137] if you are interested in solving this issue, you are welcome! I 
recommend creating a second fork, called "shiro-private" or similar. You can 
create a new branch (without creating a pull request!) which includes test etc. 
and everything. Just make sure you invite the Apache PMC members before 
creating a PR (e.g. using the maill address from above), so we can review your 
changes.

The idea here is that the tests should not be public, because they might reveal 
a "recipe" on how to exploit a given vulnerability.

Thank you very much!

Ben
