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-2026-7873 exists.\n\nAffected packages and fixed versions:\n- langflow (PyPI): affected from 1.0.0; fixed in 1.10.1.rc0\n- langflow (PyPI): affected from 1.0.0; fixed in 1.10.1.rc0\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-2026-7873/ (Markdown: https://insights.sbomify.com/CVE-2026-7873/index.md)","id":"CVE-2026-7873","markdown":"https://insights.sbomify.com/CVE-2026-7873/index.md","name":"CVE-2026-7873","record":{"aliases":["GHSA-v798-mcc6-2m3m"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Langflow OSS","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary OS commands and read sensitive files in IBM Langflow OSS, leading to system compromise.","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-94","name":"Improper Control of Generation of Code"}],"description":"IBM Langflow OSS 1.0.0 through 1.10.0 allows authenticated attackers to execute arbitrary OS commands and read sensitive files including credentials, enabling complete system compromise and lateral movement.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":"2026-06-30","github_poc":1,"max_poc_stars":3,"metasploit":1,"nuclei":0,"refs":[{"date":"2026-09-05T02:46:37Z","kind":"github_poc","ref":"https://github.com/rmhowe425/POC-CVE-2026-7873","stars":3,"title":"PoC exploit code for CVE-2026-7873"},{"date":"2026-06-30","kind":"metasploit","ref":"exploit/multi/http/langflow_auth_rce_cve_2026_7873","stars":null,"title":"Langflow AI Code Validation Authenticated RCE"}],"tier":"weaponised"},"has_fix":true,"headline":"Code Injection Vulnerability in Code Validation Endpoint","id":"CVE-2026-7873","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"langflow:langflow","products":["langflow:langflow"],"type":"code_injection","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Weak Cryptographic Key Derivation Exposed All Stored Credentials","id":"CVE-2026-7874"},"packages":[{"ecosystem":"PyPI","fixed":["1.10.1.rc0"],"introduced":["1.0.0"],"last_affected":[],"package":"langflow","purl":null,"source":"GHSA-v798-mcc6-2m3m"},{"ecosystem":"PyPI","fixed":["1.10.1.rc0"],"introduced":["1.0.0"],"last_affected":[],"package":"langflow","purl":"pkg:pypi/langflow","source":"GHSA-v798-mcc6-2m3m"}],"prev":{"headline":"Path Traversal Vulnerability in File Component Leading to Arbitrary File Read and Authentication Bypass","id":"CVE-2026-7872"},"products":["Langflow OSS"],"published":"2026-06-30","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":"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":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-01","vendors":["IBM"]},"summary":"Authenticated attackers can execute arbitrary OS commands and read sensitive files in IBM Langflow OSS, leading to system compromise.","url":"https://insights.sbomify.com/CVE-2026-7873/"}
