This critical-severity CVE scores 9.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 76% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Quest Bot is an opensource modern Discord Bot built for moderation, utilities and support. Prior to version 1.0.3, the repository has a privileged deploy workflow that runs after the unprivileged build workflow completes. The build workflow runs on pull requests, and the deploy workflow checks out the triggering workflow’s head_sha, builds that code into a Docker image, pushes it as latest, and triggers production deployment. If an attacker can open a pull request from a branch named main, the deploy workflow condition can treat the PR build as deployable and build the attacker-controlled commit in a privileged deployment context. This can result in malicious container deployment and production bot compromise. This issue has been patched in version 1.0.3.
