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-2026-42862 exists.\n\nAffected packages and fixed versions:\n- flowise (npm): affected all versions; fixed in 3.1.2\n- flowise (npm): affected all versions; fixed in 3.1.2\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-2026-42862/ (Markdown: https://insights.sbomify.com/CVE-2026-42862/index.md)","id":"CVE-2026-42862","markdown":"https://insights.sbomify.com/CVE-2026-42862/index.md","name":"CVE-2026-42862","record":{"aliases":["GHSA-x5v6-pj28-cwwm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"LLM flow builder","requires_auth":"low_privilege","summary":"Authenticated attackers can reassign tools to arbitrary workspaces via mass assignment, breaking tenant isolation in Flowise.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"flowise","vendor":"flowiseai"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-915","name":"Improperly Controlled Modification of Dynamically-Determined Object Attributes"},{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Flowise is a drag \u0026 drop user interface to build a customized large language model flow. Prior to version 3.1.2, a mass assignment vulnerability exists in the tool update endpoint of FlowiseAI. The endpoint allows authenticated users to modify server-controlled properties such as workspaceId, createdDate, and updatedDate when updating a tool resource. Due to missing server-side validation and authorization checks, an attacker can manipulate the workspaceId field and reassign tools to arbitrary workspaces. This breaks tenant isolation in multi-workspace environments. This issue has been patched in version 3.1.2.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Flowise: Mass Assignment in Tool Update Endpoint Allows Cross-Workspace Resource Reassignment","id":"CVE-2026-42862","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"flowiseai:flowise","products":["flowiseai:flowise"],"type":"missing_authorization","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Flowise: Mass Assignment in Chatflow Update Endpoint Allows Cross-Workspace AgentFlow Reassignment","id":"CVE-2026-42863"},"packages":[{"ecosystem":"npm","fixed":["3.1.2"],"introduced":["0"],"last_affected":[],"package":"flowise","purl":null,"source":"GHSA-x5v6-pj28-cwwm"},{"ecosystem":"npm","fixed":["3.1.2"],"introduced":["0"],"last_affected":[],"package":"flowise","purl":"pkg:npm/flowise","source":"GHSA-x5v6-pj28-cwwm"}],"prev":{"headline":"Flowise: Mass Assignment in Variable Update Endpoint Allows Cross-Workspace Resource Reassignment","id":"CVE-2026-42861"},"products":["Flowise"],"published":"2026-06-08","related":[{"cvss_score":10,"headline":"Flowise through 2.2.7 - Arbitrary File Write to Remote Code Execution via document-store API","id":"CVE-2025-71338","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":10,"headline":"Flowise: Authenticated RCE Via MCP Adapters","id":"CVE-2026-40933","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":10,"headline":"Flowise is vulnerable to arbitrary file read, arbitrary file write","id":"CVE-2025-61913","kev_date_added":null,"published":"2025-10-08"},{"cvss_score":10,"headline":"Flowise has Remote Code Execution vulnerability","id":"CVE-2025-59528","kev_date_added":null,"published":"2025-09-22"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2026-52098","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":9.8,"headline":"Flowise Cloud and Local Deployments have Unauthenticated Password Reset Token Disclosure that Leads to Account Takeover","id":"CVE-2025-58434","kev_date_added":null,"published":"2025-09-12"},{"cvss_score":9.8,"headline":"Unsupervised OS command execution leads to remote code execution by unauthenticated network attackers","id":"CVE-2025-8943","kev_date_added":null,"published":"2025-08-14"}],"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)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-08","vendors":["FlowiseAI"]},"summary":"Authenticated attackers can reassign tools to arbitrary workspaces via mass assignment, breaking tenant isolation in Flowise.","url":"https://insights.sbomify.com/CVE-2026-42862/"}
