Vulnerability details
phpgt/Dom provides access to modern DOM APIs. Versions of phpgt/Dom prior to 4.1.8 expose the GITHUB_TOKEN in the Dom workflow run artifact. The ci.yml workflow file uses actions/upload-artifact@v4 to upload the build artifact. This artifact is a zip of the…

current directory, which includes the automatically generated .git/config file containing the run's GITHUB_TOKEN. Seeing as the artifact can be downloaded prior to the end of the workflow, there is a few seconds where an attacker can extract the token from the artifact and use it with the GitHub API to push malicious code or rewrite release commits in your repository. Any downstream user of the repository may be affected, but the token should only be valid for the duration of the workflow run, limiting the time during which exploitation could occur. Version 4.1.8 fixes the issue.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
A data action map identifies locations where sensitive information may be exposed to unauthorized actors during processing or transfer.
Encrypting or otherwise protecting data at rest directly prevents unauthorized actors from reading sensitive information stored on disk or other media.
Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.
Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.
Retaining and monitoring training records confirms personnel have completed privacy and security awareness training on handling sensitive data, reducing the chance of unauthorized exposure due to lack of knowledge.
Monitoring directly detects unauthorized disclosure of sensitive information, enabling response to exposures.
The control's identification, isolation, alerting, and eradication steps directly limit the impact and exploitation window of unauthorized sensitive information exposure.
The media protection policy defines requirements and procedures to prevent unauthorized disclosure or access to sensitive information on media.
