Name of the Vulnerable Software and Affected Versions Gogs version 0.11.53

Description The issue allows an attacker to trigger MIME type sniffing using a crafted .eml file, leading to XSS. This is demonstrated by Internet Explorer and is caused by the lack of an "X-Content-Type-Options: nosniff" header.

Recommendations For Gogs version 0.11.53, consider implementing the "X-Content-Type-Options: nosniff" header to prevent MIME type sniffing and mitigate the risk of XSS. As a temporary workaround, restrict the handling of .eml files until a patch is available.
