CVE-2022-32167: Cloudreve - Stored XSS

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.

Security readout for executives and security teams

Plain-English summary

Cloudreve versions v1.0.0 through v3.5.3 are reported vulnerable to stored cross-site scripting through file upload behavior. A low-privileged user could share a crafted file with an administrator, potentially affecting admin-session confidentiality or integrity if the admin opens it.

Executive priority

Treat this as a moderate-priority exposure issue. It is not reported as actively exploited, but it can target administrator users and may support privilege escalation in environments where untrusted users can share files internally.

Technical view

The issue is CWE-79 stored XSS with CVSS 3.1 score 5.4. The vector is network-accessible, low complexity, requires low privileges and user interaction, and has changed scope with low confidentiality and integrity impact. Source data does not name a fixed version or vendor workaround.

Likely exposure

Exposure is most likely in Cloudreve deployments that allow low-privileged users to upload or share files with administrators, especially multi-user or self-hosted environments running v1.0.0 through v3.5.3.

Exploitation context

The bundle does not show CISA KEV listing or other evidence of active exploitation. Exploitation, as described, depends on an authenticated low-privileged user and an administrator interacting with a shared file.

Researcher notes

The record cites stored XSS in Cloudreve file upload functionality. Affected metadata is limited, with the description giving v1.0.0 through v3.5.3 while structured affected data is sparse. No patch, exploit, or workaround details are included in the provided sources.

Mitigation direction

  • Inventory Cloudreve deployments and confirm whether versions fall within v1.0.0 through v3.5.3.
  • Check Cloudreve vendor guidance for fixed versions or official workarounds before changing production systems.
  • Temporarily restrict low-privileged upload or share paths that reach administrators.
  • Limit administrator interaction with user-supplied shared files until remediation is confirmed.
  • Monitor for suspicious file shares from newly created or low-privileged accounts.

Validation and detection

  • Confirm the running Cloudreve version from trusted asset records or administrative interfaces.
  • Review whether low-privileged users can upload files and share them with administrators.
  • Check audit logs for recent user-to-admin file shares or unusual upload activity.
  • Verify file upload and share views apply safe output encoding without using offensive payloads.
  • Track vendor advisories and update remediation status when a fixed release is identified.
