9.1Critical

Attack vector: Network
Complexity: Low
Privileges needed: None
User interaction: None
Impact: High impact on confidentiality, integrity
Weakness: CWE-863

Impact

A read-only Canopy user can bypass permission boundaries and send unauthorized write or administrative requests via the monitoring proxy. They only need low-privilege read access to Canopy and a reachable monitoring target.

Root cause

Incomplete authorization checks in the experimental Canopy role and monitoring-proxy features allow read-only roles to proxy non-read requests.

Affected systems

Apache SkyWalking BanyanDB 0.11.0 before 0.11.1

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Fix & remediation

Upgrade Apache SkyWalking BanyanDB to version 0.11.1. If patching must wait, disable the experimental Canopy monitoring-proxy feature or isolate the reachable monitoring target.

AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
