CVE-2026-26217 is a critical Local File Inclusion (LFI) vulnerability in Crawl4AI versions prior to 0.8.0, where the Docker API fails to restrict `file://` URL schemes, allowing attackers to read arbitrary files from the host filesystem. The fix upgrades `crawl4ai` from `0.7.6` to `0.8.0` in `pyproject.toml` and `uv.lock`, closing a direct path to sensitive file exfiltration in any containerized deployment using this library.
A high-severity privilege escalation vulnerability was discovered in a Docker Compose configuration where the `nginx` service lacked the `no-new-privileges` security option and was running with a writable root filesystem. These misconfigurations could allow a compromised container process to gain elevated permissions or download and execute malicious payloads. The fix applies defense-in-depth by adding `no-new-privileges:true`, enforcing a read-only root filesystem, and redirecting writable path
