CVE-2026-86078

n8n (open-source workflow automation platform) is affected by a prototype pollution vulnerability in the Instance AI workflow summary feature prior to versions 2.37.7 and 2.38.2 . The function summarizeWorkflowStructure (in packages/@n8n/instance-ai/src/tools/workflows/summarize-workflow.ts) trea...

CVE-2026-86078 n8n: Prototype Pollution via Workflow Structure Summary Can Lead to Denial of Service

n8n is an open source workflow automation platform. Prior to 2.37.7 and 2.38.2, the Instance AI workflow summary used node names and connection keys from stored workflows as ordinary object keys. A workflow submitted through the REST API could contain proto or constructor, causing nested writes t...

joi: object().rename() with a template target can set the validated object's prototype

Impact Applications are affected only if a schema renames keys with a regular-expression source and a Joi.expression / Joi.x target that interpolates the pattern's own match data, combined with multiple: true , for example .rename/^x-.+$/, Joi.x'1', multiple: true . Because the target is rendered...

node-csv: Prototype replacement still reachable via columns path

Impact With columns: true and groupcolumnsbyname: true, a duplicated proto header causes the duplicate-column branch to assign an array to obj'proto', invoking the proto setter and replacing the parsed record object's prototype with attacker-controlled data. Fixed in 7.0.2 Object.hasOwn duplicate...
