It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-9277 exists.\n\nAffected packages and fixed versions:\n- langflow (PyPI): affected all versions up to 1.0.18; no fix listed\n- langflow (PyPI): affected all versions up to 1.0.18; no fix listed\n- langflow (PyPI): affected all versions up to 1.0.18; no fix listed\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-2024-9277/ (Markdown: https://insights.sbomify.com/CVE-2024-9277/index.md)","id":"CVE-2024-9277","markdown":"https://insights.sbomify.com/CVE-2024-9277/index.md","name":"CVE-2024-9277","record":{"aliases":["GHSA-355v-2rjx-fpx7","PYSEC-2026-1521"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Langflow application","requires_auth":"low_privilege","summary":"Attackers can cause denial of service in Langflow via inefficient regular expression complexity in the HTTP POST request handler.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"langflow","vendor":"langflow"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"A vulnerability classified as problematic was found in Langflow up to 1.0.18.
