SCA: security update for crawl4ai (GHSA-4qqr-vv2q-cmr5)

high Tenable Cloud Security Plugin ID 443322

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Crawl4AI is an open-source LLM friendly web crawler & scraper. Prior to 0.8.8, the Docker API server's
 SSRF protection (validate_webhook_url / validate_url_destination in deploy/docker/utils.py) used an
 explicit IPv4/IPv6 CIDR blocklist that missed several address families. An attacker could reach internal
 services and cloud metadata endpoints (e.g. 169.254.169.254) despite the filter by encoding an internal
 IPv4 address inside an IPv6 transition form, or by using the IPv6 unspecified address. Because the Docker
 API is unauthenticated by default (jwt_enabled: false), no credentials are required. This vulnerability is
 fixed in 0.8.8. (CVE-2026-53754)

Solution

Update the crawl4ai library and its related packages to version 0.8.8 or later.
