CVE-2026-44520Network attack vector

SSRF via unvalidated URL destinations and redirects

Published May 14, 2026 · Updated May 14, 2026

SSRF in Docling Graph before 1.5.1 allows remote authenticated users to access internal services through attacker-controlled URLs. URLInputHandler accepts URLs whose validator checks only the scheme and network location, then follows redirects without rejecting private, loopback, or link-local destinations. Exploitation requires control of the --source CLI argument or PipelineConfig.source API parameter and can expose internal services or cloud metadata.
