Name of the Vulnerable Software and Affected Versions showdoc versions prior to 2.10.4

Description The issue is related to stored cross-site scripting (XSS) due to unrestricted file upload. This allows an attacker to upload malicious files, potentially leading to the execution of arbitrary code in the context of the user's browser. The estimated number of potentially affected devices is not specified. There is no information provided about real-world incidents where this issue was exploited.

Recommendations For versions prior to 2.10.4, update to version 2.10.4 or later to resolve the issue. As a temporary workaround, consider restricting file uploads to minimize the risk of exploitation. Avoid using the vulnerable file upload feature until the issue is resolved.
