Name of the Vulnerable Software and Affected Versions Gogs version 0.11.66

Description The issue allows remote code execution due to improper validation of session IDs. This can be exploited through a ".." session-file forgery in the file session provider, specifically in the file.go file. The problem is related to session ID handling in the go-macaron/session code for Macaron.

Recommendations For Gogs version 0.11.66, consider disabling the session ID handling functionality in the go-macaron/session code for Macaron until a proper fix is available. Restrict access to the file session provider to minimize the risk of exploitation. Avoid using the file.go file for session management until the issue is resolved.
