Name of the Vulnerable Software and Affected Versions Dev blog version 1.0

Description The issue allows an attacker to exploit a cross-site scripting (XSS) vulnerability through an unrestricted file upload, combined with a bad entropy of filenames. This enables the attacker to upload a malicious HTML file, guess the filename of the uploaded file, and send it to a potential victim.

Recommendations For Dev blog version 1.0, as a temporary workaround, consider restricting or disabling the file upload feature until a patch is available. Additionally, improving the entropy of filenames can help minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
