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
A vulnerability was identified in AstrBotDevs AstrBot up to 4.22.1. The affected element is the function post_data.get of the component API Endpoint. Such manipulation leads to server-side request forgery. The attack may be performed from remote. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.

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 · moderate confidence

Server-side request forgery (SSRF) in AstrBot's API endpoint, specifically in the post_data.get function, allowing remote attackers to manipulate the server into making arbitrary HTTP requests to internal or external resources.

MitigationRestrict or disable the vulnerable post_data.get API function and implement strict allowlist-based URL validation with input sanitization to prevent requests to internal network resources.

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. Identify if AstrBot is installed
    Locate AstrBot installation directories or check running processes for astrbot or similar service names
    Affected if AstrBot is present and running in the environment
  2. Locate the post_data.get API endpoint
    Search for source code files containing 'post_data.get' function definition or API route handlers related to HTTP request functionality
    Affected if The post_data.get function exists in the codebase and is exposed via an API endpoint
  3. Check API accessibility
    Determine if the API endpoint accepting external requests is reachable from untrusted networks or the internet
    Affected if The vulnerable endpoint is accessible without proper authentication or network restrictions
  4. Verify URL validation is absent or weak
    Inspect the code handling the post_data.get function to determine if URL parameters are validated against an allowlist or if internal network destinations are blocked
    Affected if No strict URL validation or allowlist is implemented on the post_data.get endpoint, allowing arbitrary URL manipulation
  5. Test for internal network access
    If the endpoint is accessible, attempt to make a request to an internal resource (e.g., localhost or internal IP) using the post_data.get parameter to confirm the SSRF behavior
    Affected if The server can be induced to make HTTP requests to internal resources through the vulnerable endpoint

The environment is affected if AstrBot is running with the post_data.get API endpoint exposed and lacking proper URL validation, allowing arbitrary HTTP requests.
