The impact is: execute arbitrary code (remote). The component is: src/backend/base/langflow/api/v1/validate.py:validate-post_validate_code-a-real-authenticated-http-post-to-api-v1. The attack vector is: Attack surface: HTTP or browser-backed service path. A public-facing route accepts raw Python source and forwards it into a server-side compile/exec validation path without any visible entitlement guard. ¶¶ A weakness has been identified in langflow-ai langflow up to 1.9.3. langflow contains a code injection vulnerability in validate-post_validate_code-a-real-authenticated-http-post-to-api-v1 (src/backend/base/langflow/api/v1/validate.py:13). An authenticated attacker can execute arbitrary Python code on the server by submitting malicious code to the /api/v1/validate/code endpoint, which directly executes user-supplied code without sandboxing or security controls.","state":0,"publishedAt":"2026-10-01T00:00:00+00:00","modifiedAt":"2026-10-05T23:56:49.602+00:00","affected":[{"ecosystem":"Vendor product","name":"n/a","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"n/a\",\n                    \"versions\": [\n                        {\n                            \"version\": \"n/a\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/langflow-ai/langflow/issues/13336","https://gist.github.com/Ro1ME/c11b1e63e4e8fca6b25275144f25ec2a"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-51886","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-51886","identifiers":["CVE-2026-51886"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
