Hello,

Hello Team,

With reference of your security responsible program , I found RSA server private keys that are leak in the given end point of the link.

STEPS TO REPRODUCE
Open the given link below so you will see RSA keys leak as given .

https://www.projects.blender.org/archive/flamenco-manager/src/branch/master/tls/privkey.pem

IMPACT
If an Attacker obtain these key he could used to encrypt and decrypt secret information. The compromised key can be used to decrypt encrypted data without the knowledge of the sender of the data. These keys should be restricted from the Public.

Hi @SYED-MUHAMMAD-ASIM .

Thanks for letting us know. Next time, please take the responsible route and contact us slightly more privately, instead of writing a publicly readable report with a link to the private key and a copy of that key.

What you found is not a security issue, though. It's just a self-signed certificate for localhost that's useful for development purposes (as you can see in https://projects.blender.org/archive/flamenco-manager/src/branch/master/tls/cert.pem). This key was never used in any deployment of Flamenco by Blender Institute.
