Name of the Vulnerable Software and Affected Versions fastreader Gem version 1.0.8

Description The issue allows remote attackers to execute arbitrary commands via shell metacharacters in a URL, potentially triggered by specially crafted input containing a ';' character. This may enable a context-dependent attacker to execute arbitrary commands.

Recommendations For fastreader Gem version 1.0.8, consider disabling the handling of URLs with shell metacharacters or the ; character as a temporary workaround until a patch is available. Restrict access to the lib/entry controller.rb file to minimize the risk of exploitation. Avoid using URLs with specially crafted input that contains a ; character in the affected API endpoint until the issue is resolved.
