Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90534 in the wild and no public exploit code.\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-2026-90534/ (Markdown: https://insights.sbomify.com/CVE-2026-90534/index.md)","id":"CVE-2026-90534","markdown":"https://insights.sbomify.com/CVE-2026-90534/index.md","name":"CVE-2026-90534","record":{"aliases":["GHSA-hqvm-7539-v83j","GHSA-wfvf-r9gr-6qfq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"LLM application platform","requires_auth":"low_privilege","summary":"Authenticated users can access credentials from other workspaces via an unsecured API endpoint, enabling unauthorized third-party provider calls and metadata disclosure.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"flowise","vendor":"flowiseai"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Flowise is a low-code platform for building LLM applications. In versions up to and including 3.1.3, the POST /api/v1/node-load-method/:name endpoint is mounted without any route-level permission check and invokes component loadMethods with an attacker-controlled nodeName, loadMethod, inputs, and credential value. The selected credential is resolved by raw Credential.id via getCredentialData() and decrypted without verifying Credential.workspaceId against the caller's active or shared workspace, unlike other credential read paths which are workspace-scoped. As a result, an authenticated low-privilege user (or workspace API key) in one workspace can supply a credential ID owned by another workspace and cause Flowise to act as a confused deputy, performing third-party provider calls with the victim workspace's credential and returning provider metadata to the attacker. Statically identified affected load methods include Google Drive listFiles, Google Sheets listSpreadsheets, and AWS DynamoDB KV Storage listTables. The raw credential secret itself is not returned to the attacker. This issue is fixed in version 3.1.4.","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":"Flowise before 3.1.4 Cross-Workspace Credential IDOR via node-load-method","id":"CVE-2026-90534","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"flowiseai:flowise","products":["flowiseai:flowise"],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Flowise before 3.1.4 Denial of Service via text-to-speech/abort","id":"CVE-2026-90535"},"packages":[],"prev":{"headline":"Flowise before 3.1.4 Broken Access Control via organizationuser","id":"CVE-2026-90533"},"products":["Flowise"],"published":"2026-09-12","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":"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["FlowiseAI"]},"summary":"Authenticated users can access credentials from other workspaces via an unsecured API endpoint, enabling unauthorized third-party provider calls and metadata disclosure.","url":"https://insights.sbomify.com/CVE-2026-90534/"}
