CVE-2026-3351 [MEDIUM] lxd's non-recursive certificate listing bypasses per-object authorization and leaks all fingerprints
lxd's non-recursive certificate listing bypasses per-object authorization and leaks all fingerprints
## Summary
The `GET /1.0/certificates` endpoint (non-recursive mode) returns URLs containing fingerprints for all certificates in the trust store, bypassing the per-object `can_view` authorization check that is correctly applied in the recursive path. Any authenticated identity — including restricted, non-admin users — can enumerate all certificate fingerprints, exposing the full set of trusted identities in the LXD deployment.
## Affected Component
- `lxd/certificates.go` — `certificatesGet` (lines 185–192) — Non-recursive code path returns unfiltered certificate list.
## CWE
- **CWE-862**: Missing Authorization
## Description
### Core vulnerability: missing permission filter in non-r
