SCA: security update for crawl4ai (GHSA-6qhc-x826-342c)

high Tenable Self-Hosted Container Security Plugin ID 443329

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 0.8.9, the Docker API server
 applied its SSRF destination check to the crawl target URL only, not to the proxy address. An
 unauthenticated request could supply a proxy pointing at an internal IP and route the browser through it,
 reaching internal services and cloud-metadata endpoints, while using a perfectly valid crawl URL. The
 Docker API is unauthenticated by default. /crawl, /crawl/stream, and /crawl/job accept a browser_config
 (and crawler_config). The following all feed Chromium's egress and were unchecked:
 browser_config.proxy_config.server, browser_config.proxy (deprecated field),
 crawler_config.proxy_config.server, and --proxy-server / --proxy-pac-url / --proxy-bypass-list / --host-
 resolver-rules flags in browser_config.extra_args. This vulnerability is fixed in 0.8.9. (CVE-2026-53755)

Solution

Update the crawl4ai library and its related packages to version 0.8.9 or later.
