Vulnerability in EdgeEver (CVE-2026-108727)

Summary

Vulnerability in EdgeEver (CVE-2026-108727). Risk of unauthorized operations or information disclosure. Exploitable via POST /api/v1/templates/.

Original description

The description as published by the source.

EdgeEver through 1.108.0 contains a missing authorization vulnerability in the Hono API memo-template routes that allows holders of scoped API tokens to bypass token scope restrictions because template handlers never call requireScopes. Attackers with a token lacking write:memos can save a template and invoke POST /api/v1/templates/:id/use to create memos, and list, modify, or delete templates in the token owner's workspace.

Attack vector: remote (network-reachable) / no user interaction
Attack surface: POST /api/v1/templates/
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.

❓ What is the problem

A vulnerability (CWE-862) exists in EdgeEver. Attackers reach the vulnerable code path via POST /api/v1/templates/.

📍 Affected scope

Check the vendor advisory for the affected versions of EdgeEver. Attack surface: POST /api/v1/templates/.

🔥 Severity

Severity: Medium (CVSS 4.3/10). Risk of unauthorized operations or information disclosure.

🔧 How to fix

Update to the patched release per vendor advisory.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual POST /api/v1/templates/ requests with malformed payloads or SQL meta-characters. Run grep -r 'EdgeEver' . 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

  1. 1
    Identify exposure identify 
    grep -r 'EdgeEver' . | 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 EdgeEver を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Hunt for indicators of compromise detect 
    grep 'POST /api/v1/templates/' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'

    アクセスログで POST /api/v1/templates/ 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。

  3. 3
    Post-deployment verification verify 
    Replay attack against POST /api/v1/templates/ 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。
