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
1Panel versions 1.10.33 - 2.0.15 contain a cross-site request forgery (CSRF) vulnerability in the web port configuration functionality. The port-change endpoint lacks CSRF defenses such as anti-CSRF tokens or Origin/Referer validation. An attacker can craft a malicious webpage that submits a port-change request; when a victim visits it while authenticated, the browser includes valid session cookies and the request succeeds. This allows an attacker to change the port on which the 1Panel web service listens, causing loss of access on the original port and resulting in service disruption or denial of service, and may unintentionally expose the service on an attacker-chosen port.

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

1Panel versions 1.10.33 through 2.0.15 have a CSRF vulnerability in the web port configuration endpoint. The port-change functionality does not implement anti-CSRF tokens or validate Origin/Referer headers, allowing attackers to trick authenticated users into unknowingly changing the web service listening port.

MitigationImplement anti-CSRF token validation on the port-change endpoint or add Origin/Referer header validation to prevent cross-origin requests.

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 1Panel version
    Run the command '1pctl version' in the terminal, or check the Docker container image tag if running via Docker
    Affected if The version displayed falls within 1.10.33-lts through 2.0.15 (inclusive)
  2. Check for web interface availability
    Verify the 1Panel web interface is accessible by attempting to reach the configured port (default 20480) via HTTP/HTTPS
    Affected if The web interface is reachable and responds, meaning the vulnerable endpoint is exposed
  3. Verify no reverse proxy or firewall blocks the endpoint
    Check if the port configuration endpoint is accessible from the network where social engineering attacks could occur
    Affected if The web interface port is accessible from untrusted networks without additional authentication

You are affected if your installed 1Panel version is between 1.10.33-lts and 2.0.15 (inclusive) and the web management interface is enabled and accessible.
