## Overview

@e2e-dev/github before 0.4.1 contains an improper authorization vulnerability that allows pull request commenters to hijack CI test reports by posting comments with the predictable marker. Because findComment and upsertComment in post.ts never check the comment author, attackers can receive results in their own comment and edit failures to passes, or suppress genuine reports entirely.

## Affected

- `@e2e-dev/github < 0.4.1`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
