Description
Incorrect access control in SigningHub v8.6.8 allows attackers to arbitrarily add user accounts without any rate limiting. This can lead to a resource exhaustion and a Denial of Service (DoS) when an excessively large number of user accounts are created.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
