An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-7871 in the wild and no public exploit code.\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-2026-7871/ (Markdown: https://insights.sbomify.com/CVE-2026-7871/index.md)","id":"CVE-2026-7871","markdown":"https://insights.sbomify.com/CVE-2026-7871/index.md","name":"CVE-2026-7871","record":{"aliases":["GHSA-2fmj-c726-jmv7"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Langflow OSS","requires_auth":"none","summary":"Attackers with Redis access can execute arbitrary code via insecure deserialization, compromising application secrets and system integrity.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"langflow","vendor":"langflow"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"IBM Langflow OSS 1.0.0 through 1.10.0 allows users with Redis access to execute arbitrary code with full application privileges, compromising all secrets, data, and system integrity.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Insecure Deserialization in Redis Cache Backend","id":"CVE-2026-7871","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"langflow:langflow","products":["langflow:langflow"],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Path Traversal Vulnerability in File Component Leading to Arbitrary File Read and Authentication Bypass","id":"CVE-2026-7872"},"packages":[],"prev":{"headline":"IBM i is Affected by Privilege Escalation []","id":"CVE-2026-7870"},"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":"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)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-01","vendors":["IBM"]},"summary":"Attackers with Redis access can execute arbitrary code via insecure deserialization, compromising application secrets and system integrity.","url":"https://insights.sbomify.com/CVE-2026-7871/"}
