Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-19295 exists.\n\nAffected product: Langflow Langflow. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-19295/ (Markdown: https://insights.sbomify.com/CVE-2026-19295/index.md)","id":"CVE-2026-19295","markdown":"https://insights.sbomify.com/CVE-2026-19295/index.md","name":"CVE-2026-19295","record":{"aliases":["GHSA-74fg-mx2g-3cx8"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Langflow OSS","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary OS commands by bypassing custom component restrictions, leading to privilege escalation.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"langflow","vendor":"langflow"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-95","name":"Improper Neutralization of Directives in Dynamically Evaluated Code"}],"description":"IBM Langflow OSS 1.0.0 through 1.11.1 allows an authenticated attacker to execute arbitrary operating system commands in the server process by saving a flow with a crafted type field value and triggering a build of a wrapper flow that references it.
