CVE-2026-56266 – Server-Side Request Forgery (SSRF) – Crawl4AI before 0.8.7

Be the first to know when new zero-days emerge:

Summary

CVE-2026-56266 is a critical Server-Side Request Forgery (SSRF) vulnerability in the Crawl4AI Docker API server, affecting all versions before 0.8.7. The flaw resides in the /crawl, /crawl/stream, /md, and /llm endpoints, which fetch arbitrary user-supplied URLs without adequate validation, and whose internal-address blocklist can be circumvented by encoding target addresses as IPv6-mapped IPv4 addresses. Unauthenticated remote attackers can exploit this to reach internal services and cloud metadata endpoints, with a CVSS v4.0 score of 9.2 (Critical).

Technical details

  • Root cause: The /crawl, /crawl/stream, /md, and /llm endpoints accept and fetch user-supplied URLs without sufficient destination validation. The internal-address blocklist fails to account for IPv6-mapped IPv4 representations (e.g., ::ffff:<internal-IP>), allowing the blocklist to be bypassed entirely.
  • Trigger conditions: An unauthenticated attacker submits a request to any of the affected endpoints with a crafted URL that encodes a blocked internal IPv4 address in IPv6-mapped form.
  • Attack vector: Fully network-exploitable with no authentication required. The Crawl4AI Docker API server runs with JWT authentication disabled by default, meaning no credentials or session token are needed to interact with the affected endpoints.
  • Impact: Successful exploitation allows the attacker to make the server issue arbitrary HTTP requests to internal network hosts and cloud metadata services (e.g., cloud instance metadata endpoints), potentially enabling exfiltration of cloud credentials and further lateral movement within the hosting environment.

Affected software

  • Crawl4AI (PyPI package crawl4ai) — all versions before 0.8.7

Severity

CVSS v3.1 Base Score: 8.6 (HIGH)
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N

CVSS v4.0 Base Score: 9.2 (CRITICAL)
Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: Upgrade Crawl4AI to version 0.8.7 or later, which contains the vendor-issued fix for the IPv6-mapped IPv4 blocklist bypass in the direct crawl endpoints.
  • Enable API authentication: Set the CRAWL4AI_API_TOKEN environment variable to require a bearer token on all API requests.
  • Replace the default JWT secret: Set a strong SECRET_KEY value (minimum 32 characters) to replace the default hardcoded credential shipped with the project.
  • Network isolation: Restrict access to the Docker API server at the network perimeter — the service should not be directly reachable from the internet.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
