Background
Gogs (aka Go Git Service) is an open-source self-hosted Git service written in Go. It provides a lightweight and efficient way to manage repositories, users, and organizations. Gogs allows users to collaborate on code, track issues, and perform various Git operations. However, versions 0.3.1-9 through 0.5.x before 0.5.8 are vulnerable to a cross-site scripting (XSS) attack.
Vulnerability Detail
The vulnerability exists in the 'models/issue.go' file of Gogs. It allows remote attackers to inject arbitrary web script or HTML through the 'text' parameter of the 'api/v1/markdown' endpoint. This can lead to the execution of malicious code in the context of other users' browsers, potentially compromising their accounts or stealing sensitive information. The vulnerability has a moderate severity rating and is classified under CWE-79.
How To Fix
Latest published version: v0.13.3 as of 22 Oct 2026

Workaround
If upgrading to the latest version is not immediately feasible, a temporary workaround is to disable the 'api/v1/markdown' endpoint or implement input validation and output encoding to prevent the execution of malicious scripts. Here is an example of input validation in Go:
import (
"html"
"net/http"
)
func sanitizeInput(input string) string {
return html.EscapeString(input)
}
By sanitizing the 'text' parameter using the 'html.EscapeString' function, the XSS vulnerability can be mitigated.
Conclusion
In conclusion, the Gogs version 0.3.1-9 through 0.5.x before 0.5.8 is vulnerable to a cross-site scripting (XSS) attack. It is crucial to upgrade to the latest version or apply the recommended workaround to mitigate the risk. For further assistance or support in vulnerability remediation, please contact DevNack.com.
