Privilege Escalation in Snipe-IT (CVE-2026-86746)
Summary
Vulnerability in Snipe-IT (CVE-2026-86746). Confidential information can be exposed externally. Exploitable via POST /livewire/update.
Original description
The description as published by the source.
Snipe-IT before 8.7.0 contains an authorization bypass vulnerability in Livewire components that enforce authorization only at the route level, not within component lifecycle methods. Attackers with a valid authenticated session can replay signed component snapshots via POST /livewire/update to invoke protected methods and escalate privileges, including creating OAuth clients, minting personal access tokens, and accessing sensitive admin data.

Attack vector: remote (network-reachable)
Attack surface: POST /livewire/update
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
A vulnerability (CWE-269) exists in Snipe-IT. Attackers reach the vulnerable code path via POST /livewire/update.
Check the vendor advisory for the affected versions of Snipe-IT. Attack surface: POST /livewire/update.
Severity: Medium (CVSS 6.4/10). Confidential information can be exposed externally.
Update to the patched release per vendor advisory.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual POST /livewire/update requests with malformed payloads or SQL meta-characters. Run grep -r 'Snipe-IT' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
Response actions
Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'Snipe-IT' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
Snipe-ITを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'POST /livewire/update' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
POST /livewire/updateへの異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Post-deployment verification verify
Replay attack against POST /livewire/update on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
