What is CVE-2022-26779?

CVE-2022-26779 is a high-severity vulnerability in Apache Cloudstack, published on 15 Mar 2022. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

Apache CloudStack prior to 4.16.1.0 used insecure random number generation for project invitation tokens. If a project invite is created based only on an email address, a random token is generated. An attacker with knowledge of the project ID and the fact that the invite is sent, could generate time deterministic tokens and brute force attempt to use them prior to the legitimate receiver accepting the invite. This feature is not enabled by default, the attacker is required to know or guess the project ID for the invite in addition to the invitation token, and the attacker would need to be an existing authorized user of CloudStack.
