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-2026-12821 exists.\n\nAffected product: FlowiseAI Flowise. 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-2026-12821/ (Markdown: https://insights.sbomify.com/CVE-2026-12821/index.md)","id":"CVE-2026-12821","markdown":"https://insights.sbomify.com/CVE-2026-12821/index.md","name":"CVE-2026-12821","record":{"aliases":["GHSA-67qj-p3v2-73g7"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Flowise AI platform","requires_auth":"low_privilege","summary":"Remote attackers can exploit a path traversal flaw in the S3 Document Loader to read arbitrary files from the server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A vulnerability was determined in FlowiseAI Flowise up to 3.1.2.
