An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-48519 exists.\n\nAffected packages and fixed versions:\n- langflow (PyPI): affected all versions; fixed in 1.9.2\n- langflow (PyPI): affected all versions; fixed in 1.9.2\n- langflow (PyPI): affected all versions; fixed in 1.9.2\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-2026-48519/ (Markdown: https://insights.sbomify.com/CVE-2026-48519/index.md)","id":"CVE-2026-48519","markdown":"https://insights.sbomify.com/CVE-2026-48519/index.md","name":"CVE-2026-48519","record":{"aliases":["GHSA-v5ff-9q35-q26f","PYSEC-2026-243"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"AI workflow builder","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary Python code via the Shareable Playground feature in Langflow.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"langflow","vendor":"langflow"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.2, the \"Shareable Playground\" (or \"Public Flows\" in code) contains a critical RCE vulnerability. Shareable Playground feature works by enabling the execution of workflows by unauthenticated users, by accessing a link. Specifically, it enables the route /api/v1/build_public_tmp to execute any public flow, given a public flow ID. When the route executes the flow, it allows for providing arbitrary custom Python code as the nodes code, inside the JSON payload. The vulnerable field is data.nodes[X].data.node.template.code.value. This vulnerability is fixed in 1.9.2.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":"2026-09-22","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-22T16:35:55Z","kind":"github_poc","ref":"https://github.com/lukehebe/IBM-Langflow-CVE-2026-48519-poc","stars":0,"title":"CVE-2026-48519 pre-auth rce poc in IBM langflow \u003c= 1.9.1"}],"tier":"weaponised"},"has_fix":true,"headline":"Langflow: Unauthenticated RCE in Shareable Playgrounds","id":"CVE-2026-48519","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"langflow:langflow","products":["langflow:langflow"],"type":"code_injection","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"Langflow: Unauthenticated Shareable Playground arbitrary local or S3 file read","id":"CVE-2026-48520"},"packages":[{"ecosystem":"PyPI","fixed":["1.9.2"],"introduced":["0"],"last_affected":[],"package":"langflow","purl":null,"source":"GHSA-v5ff-9q35-q26f"},{"ecosystem":"PyPI","fixed":["1.9.2"],"introduced":["0"],"last_affected":[],"package":"langflow","purl":"pkg:pypi/langflow","source":"GHSA-v5ff-9q35-q26f"},{"ecosystem":"PyPI","fixed":["1.9.2"],"introduced":["0"],"last_affected":[],"package":"langflow","purl":"pkg:pypi/langflow","source":"PYSEC-2026-243"}],"prev":{"headline":"MultiJuicer: Login CSRF allows attacker to force victims into their team","id":"CVE-2026-48518"},"products":["langflow"],"published":"2026-06-23","related":[{"cvss_score":9.8,"headline":"IBM Langflow Code Injection","id":"CVE-2026-9198","kev_date_added":"2026-08-04","published":"2026-07-17"},{"cvss_score":9.8,"headline":"Langflow Inclusion of Functionality from Untrusted Control Sphere","id":"CVE-2026-0770","kev_date_added":"2026-07-21","published":"2026-01-23"},{"cvss_score":9.8,"headline":"Langflow Missing Authentication","id":"CVE-2025-3248","kev_date_added":"2025-05-05","published":"2025-04-07"},{"cvss_score":9.4,"headline":"Langflow Origin Validation Error","id":"CVE-2025-34291","kev_date_added":"2026-05-21","published":"2025-12-05"},{"cvss_score":9.3,"headline":"Langflow Code Injection","id":"CVE-2026-33017","kev_date_added":"2026-03-25","published":"2026-03-20"},{"cvss_score":8.4,"headline":"Langflow Authorization Bypass Through User-Controlled Key","id":"CVE-2026-55255","kev_date_added":"2026-07-07","published":"2026-06-23"},{"cvss_score":10,"headline":"Unauthenticated Server-Side RCE via PythonCodeStructuredTool in Public Flows","id":"CVE-2026-10134","kev_date_added":null,"published":"2026-06-30"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-24","vendors":["langflow-ai"]},"summary":"Unauthenticated attackers can execute arbitrary Python code via the Shareable Playground feature in Langflow.","url":"https://insights.sbomify.com/CVE-2026-48519/"}
