# n8n: failed-workflow error handler inherits another user's identity and credentials

n8n passes a failed workflow's full execution context, including the identity of the user who started the run, to the configured error workflow. A project editor can point a colleague's workflow at an error workflow they own and then resolve the colleague's per-user dynamic credential secrets.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the n8n version with `n8n --version`; affected builds are before `2.41.5` and `2.42.x` before `2.42.2`
- Review workflow settings for `errorWorkflow` values pointing to workflows owned by other users
- unknown whether the sources describe a further check

## Fix

- Upgrade n8n to `2.41.5` or later on the 2.41 line, or to `2.42.2` or later on the 2.42 line
- Rotate per-user dynamic credential secrets if an untrusted editor could have set an error workflow

## From the sources

n8n before 2.41.5 and 2.42.x before 2.42.2 passes a failed workflow's full execution context, including the identity of the user who started the run, to the configured error workflow. A project editor can set a colleague's workflow settings.errorWorkflow to an error workflow they own, inherit the colleague's identity when that workflow fails, and resolve the colleague's per-user dynamic credential secrets.
