Vulnerability in Kaneo (CVE-2026-63104)

Summary

Vulnerability in Kaneo (CVE-2026-63104). Data can be tampered with by attackers. Exploitable via PATCH /api/task/bulk.

Original description

The description as published by the source.

Kaneo versions 2.3.12 before 2.12.2 contain a missing authorization vulnerability that allows authenticated workspace members with viewer or member roles to delete and modify tasks beyond their assigned permissions by exploiting the bulk task endpoint that omits workspace permission checks. Attackers can send requests to the PATCH /api/task/bulk endpoint, which verifies only workspace membership without calling the role-based permission check enforced on all other task endpoints, to permanently delete all tasks or modify task status, priority, assignee, due date, and labels in a workspace.

❓ What is the problem

A vulnerability (CWE-862) exists in Kaneo. Attackers reach the vulnerable code path via PATCH /api/task/bulk.

📍 Affected scope

Check the vendor advisory for the affected versions of Kaneo. Attack surface: PATCH /api/task/bulk.

🔥 Severity

Severity: High (CVSS 8.1/10). Data can be tampered with by attackers.

🔧 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 PATCH /api/task/bulk requests with malformed payloads or SQL meta-characters. Run grep -r 'Kaneo' . 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 'Kaneo' . | 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 Kaneo 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 'PATCH /api/task/bulk' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'

    アクセスログで PATCH /api/task/bulk 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 PATCH /api/task/bulk 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。
