GHSA-6G59-GM2V-QHVQ

Vulnerability from github – Published: 2026-10-07 20:22 – Updated: 2026-10-07 20:22
VLAI
Summary
PraisonAI: Crawl4AI/Chromium backend is also affected by the `web_crawl` SSRF validation bypass
Details

Summary

The DNS-rebinding / redirect SSRF bypass in PRAI-05 is not limited to the httpx/urllib backend. When crawl4ai (headless Chromium via Playwright) is installed, web_crawl auto-selects provider=crawl4ai, and the headless browser re-resolves DNS and follows redirects on its own — with no per-connection SSRF guard. Runtime-confirmed read-back of the internal canary via both DNS rebinding and redirect (provider: "crawl4ai"). Status: runtime-confirmed addendum to PRAI-05.

Details

Affected component

  • Package praisonaiagents 4.6.63. Backend selected when crawl4ai+Playwright are installed.
  • Files: src/praisonai-agents/praisonaiagents/tools/web_crawl_tools.py (_crawl_with_crawl4ai) and src/praisonai-agents/praisonaiagents/tools/crawl4ai_tools.py (standalone crawl wrappers).

Vulnerable code / root cause

Path: src/praisonai-agents/praisonaiagents/tools/web_crawl_tools.py

Function: _crawl_with_crawl4ai

Snippet:

async with AsyncWebCrawler() as crawler:
    for url in urls:
        result = await crawler.arun(url=url)   # headless browser: re-resolves DNS, follows redirects

Path: src/praisonai-agents/praisonaiagents/tools/crawl4ai_tools.py

Function: Crawl4AITools.crawl / crawl4ai

Snippet:

result = await crawler.arun(url=url, config=config)   # no _is_safe_crawl_url / no per-connect validation

Issue: the only SSRF check is the single pre-fetch _is_safe_crawl_url() on the initial URL string in web_crawl() (see PRAI-05). The headless browser then resolves and connects independently and follows redirects in-browser — no resolved-IP pinning, no per-hop/per-connect validation. Input (urls) is attacker/agent-controlled; the sink is crawler.arun(url=...); the guard is bypassed by DNS rebinding (TOCTOU) and by redirects (followed in-browser).

Attack flow / Why bypassed / Security boundary

Identical to PRAI-05: TOCTOU between the guard's resolution and the browser's connection; redirects followed in-browser; internal response returned as crawl content. See PRAI-05.

Proof of Concept

Environment

crawl4ai + Playwright Chromium installed in a dedicated runtime container (127.0.0.1:18081), same controlled internal canary + rebinding DNS. Runnable assets: PraisonAI-Runtime-Repro\runtime-files\ (docker-compose.crawl.yml).

Steps to reproduce

  1. SSRF-04-01-Crawl4AI-DNS-Rebind-Trigger → 127.0.0.1:18081:
POST /tool/web_crawl HTTP/1.1
Host: 127.0.0.1:18081
Content-Type: application/json

{"url":"http://rebind.lab:8081/secret"}
  1. Redirect variant SSRF-04-03-Crawl4AI-Redirect-Readback: {"url":"http://redirector:8082/redirect-to-internal"}.

Expected result

The crawl backend refuses internal destinations regardless of DNS timing/redirects.

Actual result

HTTP 200, "provider":"crawl4ai", response content contains PRAISONAI_INTERNAL_SECRET_CANARY_7f3a91 + FAKE_INTERNAL_TOKEN_DO_NOT_USE_7f3a91 for both the DNS-rebinding and the redirect payload.

Screenshots

Crawl4AI DNS rebinding read-back

The attacker-controlled rebind.lab URL is accepted by the Crawl4AI-backed web_crawl endpoint. PraisonAI returns the internal canary response body containing PRAISONAI_INTERNAL_SECRET_CANARY_7f3a91.

01-Crawl4AI-Burp-Readback

Crawl4AI DNS rebinding runtime evidence

The runtime log shows the Crawl4AI/Chromium backend resolving rebind.lab to an internal Docker IP during the fetch phase. The internal canary receives GET /secret from a headless Chrome user agent.

Crawl4AI redirect read-back

The attacker-controlled redirector URL is accepted by the Crawl4AI-backed endpoint. PraisonAI follows the redirect and returns the internal canary response body.

03-Crawl4AI-Redirect-Readback

Crawl4AI redirect runtime evidence

The controlled redirector returns 302 -> http://internal-canary:8081/secret, and the internal canary receives GET /secret from the Crawl4AI/Chromium backend.

04-Crawl4AI-Redirect-Internal-Hit-Log

Impact

Same class as PRAI-05: read-back SSRF to internal/metadata services, now on the crawl4ai backend. Broadens the affected surface (the flaw is in the shared validate-without-pinning design, not one backend).

Suggested remediation

Resolve-once + IP-pin + per-connect validation must also cover the crawl4ai backend (constrain the headless browser to the validated IP, or allowlist crawl destinations).

  "details": "## Summary\n\nThe DNS-rebinding / redirect SSRF bypass in PRAI-05 is **not limited to the httpx/urllib backend**. When `crawl4ai` (headless Chromium via Playwright) is installed, `web_crawl` auto-selects `provider=crawl4ai`, and the headless browser re-resolves DNS and follows redirects on its own \u2014 with no per-connection SSRF guard. Runtime-confirmed read-back of the internal canary via both DNS rebinding and redirect (`provider: \"crawl4ai\"`). Status: runtime-confirmed addendum to PRAI-05.\n\n## Details\n\n### Affected component\n- Package `praisonaiagents` 4.6.63. Backend selected when `crawl4ai`+Playwright are installed.\n- Files: `src/praisonai-agents/praisonaiagents/tools/web_crawl_tools.py` (`_crawl_with_crawl4ai`) and `src/praisonai-agents/praisonaiagents/tools/crawl4ai_tools.py` (standalone crawl wrappers).\n\n### Vulnerable code / root cause\n\nPath:\n`src/praisonai-agents/praisonaiagents/tools/web_crawl_tools.py`\n\nFunction:\n`_crawl_with_crawl4ai`\n\nSnippet:\n```python\nasync with AsyncWebCrawler() as crawler:\n    for url in urls:\n        result = await crawler.arun(url=url)   # headless browser: re-resolves DNS, follows redirects\n```\n\nPath:\n`src/praisonai-agents/praisonaiagents/tools/crawl4ai_tools.py`\n\nFunction:\n`Crawl4AITools.crawl` / `crawl4ai`\n\nSnippet:\n```python\nresult = await crawler.arun(url=url, config=config)   # no _is_safe_crawl_url / no per-connect validation\n```\n\nIssue: the only SSRF check is the single pre-fetch `_is_safe_crawl_url()` on the initial URL string in `web_crawl()` (see PRAI-05). The headless browser then resolves and connects independently and follows redirects in-browser \u2014 no resolved-IP pinning, no per-hop/per-connect validation. Input (`urls`) is attacker/agent-controlled; the sink is `crawler.arun(url=...)`; the guard is bypassed by DNS rebinding (TOCTOU) and by redirects (followed in-browser).\n\n### Attack flow / Why bypassed / Security boundary\nIdentical to PRAI-05: TOCTOU between the guard\u0027s resolution and the browser\u0027s connection; redirects followed in-browser; internal response returned as crawl `content`. See PRAI-05.\n\n## Proof of Concept\n\n### Environment\n`crawl4ai` + Playwright Chromium installed in a dedicated runtime container (`127.0.0.1:18081`), same controlled internal canary + rebinding DNS. Runnable assets: `PraisonAI-Runtime-Repro\\runtime-files\\` (`docker-compose.crawl.yml`).\n\n### Steps to reproduce\n1. `SSRF-04-01-Crawl4AI-DNS-Rebind-Trigger` \u2192 `127.0.0.1:18081`:\n```http\nPOST /tool/web_crawl HTTP/1.1\nHost: 127.0.0.1:18081\nContent-Type: application/json\n\n{\"url\":\"http://rebind.lab:8081/secret\"}\n```\n2. Redirect variant `SSRF-04-03-Crawl4AI-Redirect-Readback`: `{\"url\":\"http://redirector:8082/redirect-to-internal\"}`.\n\n### Expected result\nThe crawl backend refuses internal destinations regardless of DNS timing/redirects.\n\n### Actual result\nHTTP 200, `\"provider\":\"crawl4ai\"`, response `content` contains `PRAISONAI_INTERNAL_SECRET_CANARY_7f3a91` + `FAKE_INTERNAL_TOKEN_DO_NOT_USE_7f3a91` for both the DNS-rebinding and the redirect payload.\n\n### Screenshots\n\n**Crawl4AI DNS rebinding read-back**\n\nThe attacker-controlled `rebind.lab` URL is accepted by the Crawl4AI-backed `web_crawl` endpoint. PraisonAI returns the internal canary response body containing `PRAISONAI_INTERNAL_SECRET_CANARY_7f3a91`.\n\n\u003cimg width=\"1542\" height=\"763\" alt=\"01-Crawl4AI-Burp-Readback\" src=\"https://github.com/user-attachments/assets/a03b3a1c-e382-4f67-8ea6-b766dceb4a69\" /\u003e\n\n**Crawl4AI DNS rebinding runtime evidence**\n\nThe runtime log shows the Crawl4AI/Chromium backend resolving `rebind.lab` to an internal Docker IP during the fetch phase.

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
