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
Cloudreve versions v1.0.0 through v3.5.3 are vulnerable to Stored Cross-Site Scripting (XSS), via the file upload functionality. A low privileged user will be able to share a file with an admin user, which could lead to privilege escalation.

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
How this class of weakness works · CWE-79

Untrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.

Upgrade available Upgrade to a release after 3.5.3
Recommended fix Moderate confidence

Upgrade to Cloudreve version 3.5.4 or later (latest stable release)

  1. 1. Back up your current Cloudreve installation and database before proceeding with the upgrade.
  2. 2. Download the latest stable version of Cloudreve from the official GitHub repository (https://github.com/cloudreve/Cloudreve).
  3. 3. Follow the official upgrade instructions for your deployment method (Docker or manual installation).
  4. 4. If using Docker, update your image tag to the latest version and recreate containers.
  5. 5. If using manual installation, replace the existing binary with the new version and run any provided migration scripts.
  6. 6. Verify the upgrade was successful by logging into the admin panel.
  7. 7. Test the file upload and sharing functionality to confirm the XSS vulnerability is no longer present.
