Name of the Vulnerable Software and Affected Versions MaaAssistantArknights (affected versions not specified)

Description In the dev-v2 workflow, the .github/workflows/release-preparation.yml file inlines the attacker-controlled github.event.pull request.title variable into a shell command. This occurs during the pull request opened, reopened, and ready for review events. Consequently, a non-draft fork pull request with a title starting with "Release v" can execute arbitrary shell commands on the ubuntu-latest runner during the generate-changelog job.

Recommendations Apply the fix provided in commit cafc3946059e6337d2089d4fec8b6885ba17c332.
