Vulnerability in praisonai (CVE-2026-61428)
Summary
Vulnerability in praisonai (CVE-2026-61428). Risk of unauthorized operations or information disclosure. Exploitable via POST /webhook. Mitigation: upgrade to 4.6.78 or later.
Original description
The description as published by the source.
Summary
PraisonAI's AgentMail bot, when run in webhook (or hybrid) mode, starts an aiohttp webhook server bound to 0.0.0.0 and processes inbound message.received events without verifying any signature/HMAC and without authentication. The sender address and message body are taken directly from the attacker-controlled request body, so any network peer can inject messages into the agent with a spoofed sender (bypassing sender allow/block lists) and have the agent process the content and reply to an attacker-chosen address. Sibling bots (linear.py, whatsapp.py) fail closed when no secret is configured; AgentMail omits the check entirely. Runtime-confirmed; severity Medium.

Attack vector: remote (network-reachable) / unauthenticated / no user interaction
Attack surface: POST /webhook / GET /webhook-log / message.received / linear.py
Patched: 4.6.78 — apply immediately
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-290) exists in praisonai. Attackers reach the vulnerable code path via POST /webhook without authentication.
Check the vendor advisory for the affected versions of praisonai. Attack surface: POST /webhook / GET /webhook-log / message.received / linear.py.
Severity: High (CVSS 7.3/10). Risk of unauthorized operations or information disclosure.
Update to 4.6.78.
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 /webhook requests with malformed payloads or SQL meta-characters. Run grep -r 'praisonai' . 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 'praisonai' . | 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
praisonai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 /webhook' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
POST /webhook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。 -
3Apply patch patch
Upgrade praisonai to 4.6.78ステージング環境で 4.6.78 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 2 で見つけた異常検知の続報チェックを含めること。
-
4Post-deployment verification verify
Replay attack against POST /webhook 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。
