There are 3 open security issues in bullseye.
1 important issue:
Versions of the package sidekiq before 7.1.3 are vulnerable to Denial of Service (DoS) due to insufficient checks in the dashboard-charts.js file. An attacker can exploit this vulnerability by manipulating the localStorage value which will cause excessive polling requests.
2 issues left for the package maintainer to handle:
Sidekiq through 5.1.3 and 6.x through 6.2.0 allows XSS via the queue name of the live-poll feature when Internet Explorer is used.
In api.rb in Sidekiq before 5.2.10 and 6.4.0, there is no limit on the number of days when requesting stats for the graph. This overloads the system, affecting the Web UI, and makes it unavailable to users.
You can find information about how to handle these issues in the security team's documentation.
