CVE-2024-32887

Sidekiq is simple, efficient background processing for Ruby. Sidekiq is
reflected XSS vulnerability. The value of substr parameter is reflected in
the response without any encoding, allowing an attacker to inject
Javascript code into the response of the application. An attacker could
exploit it to target users of the Sidekiq Web UI. Moreover, if other
applications are deployed on the same domain or website as Sidekiq, users
of those applications could also be affected, leading to a broader scope of
compromise. Potentially compromising their accounts, forcing the users to
perform sensitive actions, stealing sensitive data, performing CORS
attacks, defacement of the web application, etc. This issue has been
patched in version 7.2.4.
