Crawl4AI < 0.8.0 - Local File Inclusion

The Crawl4AI Docker API endpoints accepted arbitrary URL schemes without an allow-list. An unauthenticated request with a file:// URL could read local files. Fixed in 0.8.0, which restricts accepted URL schemes. id: CVE-2026-26217 info: name: Crawl4AI 0.8.0 - Local File Inclusion author:...

Crawl4AI <= 0.8.6 - Remote Code Execution

Crawl4AI through 0.8.6 ships a Docker API server that exposes an unauthenticated /crawl endpoint. The computed field type of JsonCssExtractionStrategy evaluates a user supplied expression inside an AST based sandbox that does not restrict attribute access on generator frame objects. A generator...

Crawl4AI < 0.8.0 - Unauthenticated Remote Code Execution via Hooks Parameter

Crawl4AI versions prior to 0.8.0 contain a remote code execution vulnerability in the Docker API deployment. The /crawl endpoint accepts a hooks parameter containing Python code that is executed using exec. The import builtin was included in the allowed builtins, allowing unauthenticated remote...

Crawl4AI < 0.8.7 - Hardcoded JWT Signing Key Authentication Bypass

Crawl4AI Docker API server versions before 0.8.7 ship with a hardcoded default JWT signing key "mysecret" used to sign and verify HS256 authentication tokens. Because the key is identical across every deployment where SECRETKEY has not been overridden, an unauthenticated attacker can forge a vali...
