EPSS

• CVE-2025-34410: 0.16% estimated exploitation activity in the next 30 days; percentile 4.87 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

1Panel versions 1.10.33 - 2.0.15 contain a cross-site request forgery (CSRF) vulnerability in the Change Username functionality available from the settings panel (/settings/panel). The endpoint does not implement CSRF protections such as anti-CSRF tokens or Origin/Referer validation. An attacker can craft a malicious webpage that submits a username-change request; when a victim visits the page while authenticated, the browser includes valid session cookies and the request succeeds. This allows an attacker to change the victim’s 1Panel username without consent. After the change, the victim is logged out and unable to log in with the previous username, resulting in account lockout and denial of service.

# Patch Next advisory brief: CVE-2025-34410

Advisory: 1Panel contains a cross-site request forgery (CSRF) vulnerability in the Change Username functionality
IDs: CVE-2025-34410, GHSA-rpr2-4hqj-hc4q
Record: https://patchnext.com/advisories/cve-2025-34410 (revision 1, source checked 26 Oct 2026, 15:13 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/1Panel-dev/1Panel: affected >= 1.10.33, <= 2.0.15

## Suggested inspection (read-only)
- Go github.com/1Panel-dev/1Panel: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/1Panel-dev/1Panel.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-rpr2-4hqj-hc4q (GitHub-reviewed advisory GHSA-rpr2-4hqj-hc4q lists affected ranges: Go github.com/1Panel-dev/1Panel >=1.10.33 <=2.0.15)
