Short explanation

@e2e-dev/github versions prior to 0.4.1 contain an improper authorization vulnerability that allows pull request commenters to hijack CI test reports due to missing comment author validation.

Why does it matter?

This flaw compromises CI integration integrity by allowing attackers to modify failing test results into passes or suppress genuine reports entirely.

What should be done?

  • Updating to version 0.4.1 or later
  • Following vendor advisory recommendations

Show the technical text from the sources

@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.
