The server does not restrict which properties the client may modify, so requests can change server-controlled fields such as workspaceId, createdDate and updatedDate. This allows an attacker to reassign assistants to arbitrary workspaces, breaking tenant isolation in multi-workspace deployments.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-hp26-q66v-q2w7","publishedAt":"2026-05-14T14:57:46.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["flowise@<= 3.1.1 (fixed: 3.1.2)"],"affectedPackageNames":["flowise"],"affectedPackageRefs":["npm:flowise"],"affectedVendors":[],"affectedVendorsRaw":["FlowiseAI"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":["GHSA-hp26-q66v-q2w7"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-05-14T14:57:46.000Z","fixReleasedAt":"2026-04-14T10:52:03.012Z","daysToFix":-30,"fixCheckedAt":"2026-10-29T21:36:22.771Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity","confidentiality"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"flowise","fixedVersion":"3.1.2","matchedVersion":"3.1.2","fixReleasedAt":"2026-04-14T10:52:03.012Z","daysToFix":-30,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:36:22.624Z"}]}}
