As published by the source; long descriptions are shortened.

Summary DPanel has an arbitrary file deletion vulnerability in the /api/common/attach/delete interface. Authenticated users can delete arbitrary files on the server via path traversal. Details When a user logs into the administrative backend, this interface can be used to delete files. The vulnerability lies in the Delete function within the app/common/http/controller/attach.go file. The path parameter submitted by the user is directly passed to storage.Local{}.GetSaveRealPath and subsequently to os.Remove without proper sanitization or checking for path traversal characters (../). The vulnerable code snippet: <img width="487" height="363" alt="image" src="https://github.com/user-attachments/assets/b811de6f-1df1-49f3-af78-ea77bc420804" / And the helper function in common/service/storage/local.go uses filepath.Join, which resolves ../ but does not enforce a chroot/jail: <img width="564" height="66" alt="image"…

# Patch Next advisory brief: CVE-2025-66292

Advisory: DPanel has an arbitrary file deletion vulnerability in /api/common/attach/delete interface
IDs: CVE-2025-66292, GHSA-vh2x-fw87-4fxq
Record: https://patchnext.com/advisories/cve-2025-66292 (revision 1, source checked 26 Oct 2026, 15:14 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/donknap/dpanel 1.9.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/donknap/dpanel: affected < 1.9.2; fixed in 1.9.2

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

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/donknap/dpanel.
- 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-vh2x-fw87-4fxq (GitHub-reviewed advisory GHSA-vh2x-fw87-4fxq lists affected ranges: Go github.com/donknap/dpanel >=0 <1.9.2)
