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-2026-55423 exists.\n\nAffected packages and fixed versions:\n- langflow (PyPI): affected all versions; fixed in 1.7.0\n- langflow (PyPI): affected all versions; fixed in 1.7.0\n- langflow (PyPI): affected all versions; fixed in 1.7.0\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-2026-55423/ (Markdown: https://insights.sbomify.com/CVE-2026-55423/index.md)","id":"CVE-2026-55423","markdown":"https://insights.sbomify.com/CVE-2026-55423/index.md","name":"CVE-2026-55423","record":{"aliases":["GHSA-7hw8-6q6r-4276","PYSEC-2026-222"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AI workflow builder","requires_auth":"none","summary":"Attackers can retain access to a user's session after logout, potentially leading to unauthorized account access in Langflow.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"langflow","vendor":"langflow"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"Langflow is a tool for building and deploying AI-powered agents and workflows.
