# tj-actions changed-files before 46 allows remote attackers to discover secrets by reading actions logs

The tj-actions/changed-files GitHub Action contained embedded malicious code that printed secrets into GitHub Actions workflow logs. An attacker who can read those logs can collect AWS keys, GitHub personal access tokens, npm tokens and private RSA keys.

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

## Affected

- vendor:tj-actions changed-files GitHub Action affected ? fixed ?
- vendor:tj-actions changed-files affected <= 45.0.7 fixed ?

## How to check

Search workflow run logs for uses: tj-actions/changed-files in your workflow files and check which version is pinned.

## Fix

Pin the action to a version that is not affected, or remove it; rotate any AWS keys, GitHub PATs, npm tokens and SSH/RSA keys that ran through workflows using it.

## From the sources

tj-actions/changed-files GitHub Action contains an embedded malicious code vulnerability that allows a remote attacker to discover secrets by reading Github Actions Workflow Logs. These secrets may include, but are not limited to, valid AWS access keys, GitHub personal access tokens (PATs), npm tokens, and private RSA keys.

CISA required action: Apply mitigations as set forth in the CISA instructions linked below. Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
