There is 1 open security issue in bullseye.
1 issue left for the package maintainer to handle:
A flaw was found in JSS, where it did not properly free up all memory. Over time, the wasted memory builds up in the server memory, saturating the server’s RAM. This flaw allows an attacker to force the invocation of an out-of-memory process, causing a denial of service.
You can find information about how to handle this issue in the security team's documentation.
