CVE-2026-55403

CVE-2026-55403 affects the Python package datamodel-code-generator. In versions prior to 0.63.0, the code path in src/datamodel_code_generator/http.py:get_body reuses Authorization, Cookie, and Proxy-Authorization headers when following cross-origin redirects to fetch remote schemas. This can lea...

datamodel-code-generator vulnerable to SSRF via --url: no host/IP validation, follows redirects

Summary datamodel-code-generator's built-in HTTP fetcher http.getbody issues an httpx.GET against any URL passed to --url or reached via a redirect chain with no allow-list, no deny-list, no IP/host validation, and followredirects=True. Loopback addresses, RFC1918 ranges, link-local 169.254.169.2...

CVE-2026-54691

CVE-2026-54691 affects datamodel-code-generator prior to 0.61.0; the http.get_body function in src/datamodel_code_generator/http.py accepts --url targets and redirect chains without host/IP validation, enabling server-side request forgery to loopback, private, link-local, metadata, and other netw...

CVE-2026-54691 datamodel-code-generator vulnerable to SSRF via --url: no host/IP validation, follows redirects
