Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In Gogs 0.11.53, an attacker can use migrate to send arbitrary HTTP GET requests, leading to SSRF.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Gogs 0.11.53 contains a Server-Side Request Forgery (SSRF) vulnerability in its migrate feature. An attacker can abuse the migration functionality to send arbitrary HTTP GET requests to internal or external servers, potentially accessing cloud metadata services, internal infrastructure, or other sensitive resources.

MitigationUpgrade to a patched version of Gogs. If immediate patching is not feasible, restrict network access to the Gogs instance and consider disabling the migrate feature until the patch can be applied.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine installed Gogs version
    Run 'gogs --version' from the command line, check the admin dashboard under 'System Info', or inspect the Docker container metadata if running in Docker
    Affected if The version displayed is exactly 0.11.53
  2. Locate Gogs configuration file
    Find the custom/conf/app.ini file (default location) or the configuration file mounted for Docker deployments
    Affected if The [migrate] section or migration-related settings exist and are not explicitly disabled
  3. Verify migrate feature accessibility
    Log into Gogs as an authenticated user and attempt to access the migration page at '/repo/migrate' or check if migration is listed as an available action in the repository creation menu
    Affected if The migrate feature is visible and accessible to users (not removed or restricted)

You are affected if your Gogs installation is version 0.11.53 AND the migrate feature is enabled and accessible to at least some users in your deployment

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to a patched version of Gogs. If immediate patching is not feasible, restrict network access to the Gogs instance and consider disabling the migrate feature until the patch can be applied.
