SSRF (Server-Side Request Forgery) in praisonaiagents (CVE-2026-47390)

Summary

SSRF in praisonaiagents (CVE-2026-47390). Confidential information can be exposed externally. Exploitable via spider_tools. Mitigation: upgrade to 1.6.40 or later.

Original description

The description as published by the source.

Summary

PraisonAI's spider_tools URL validation can be bypassed using alternate loopback host encodings.

The affected component is:

praisonaiagents/tools/spider_tools.py

The tool contains a URL validation function intended to block local or unsafe targets before fetching attacker-controlled URLs. However, the validation only blocks a small set of exact host strings such as localhost and 127.0.0.1.

It does not normalize hostnames, resolve DNS, parse numeric IPv4 variants, or validate the final resolved IP address before making the request.

As a result, URLs such as the following bypass the protection and still reach loopback services:

http://localhost.:8765/
http://127.1:8765/
http://0177.0.0.1:8765/
http://0x7f000001:8765/
http://2130706433:8765/

After the weak validation passes, scrape_page() calls requests.Session.get() on the attacker-controlled URL. This allows an attacker who can influence URLs passed to scrape_page, crawl, or extract_text to induce SSRF requests against loopback-only services.

This is a server-side request forgery protection bypass.

Details

The affected code is in:

praisonaiagents/tools/spider_tools.py

The vulnerable flow is:

attacker-controlled URL
  -> spider_tools._validate_url(...)
  -> weak exact-host blocklist check
  -> validation passes for alternate loopback encodings
  -> scrape_page(...)
  -> requests.Session.get(attacker_url)
  -> loopback service is reached

❓ What is the problem

SSRF (CWE-918) exists in praisonaiagents. Attackers reach the vulnerable code path via spider_tools without authentication.

📍 Affected scope

Check the vendor advisory for the affected versions of praisonaiagents. Attack surface: spider_tools / localhost / scrape_page / crawl.

🔥 Severity

Severity: Medium (CVSS 5.5/10). Confidential information can be exposed externally.

🔧 How to fix

Update to 1.6.40.

🛡️ 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 request patterns matching this CVE's known IOCs. Run grep -r 'praisonaiagents' . 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 'praisonaiagents' . | 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 praisonaiagents 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
    Apply patch patch 
    Upgrade praisonaiagents to 1.6.40

    ステージング環境で 1.6.40 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を含めること。

  3. 3
    Post-deployment verification verify 
    Confirm patched version is live in production

    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。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
