Summary
### Impact A successful SSRF attack allows an attacker to: - Bypass firewalls to scan and interact with internal network services/ports. - Access sensitive cloud metadata services (e.g., AWS IMDS 169.254.169.254) to potentially leak instance credentials. - Pivot into the internal network environment where Postiz is hosted. ### Workarounds There are no workarounds known to this, please upgrade to Postiz version `v2.21.1`.
