CVE-2026-55576

HIGHPre-NVD 8.88.8—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 62% 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).

MaaAssistantArknights is a one-click tool for daily Arknights tasks. In the current dev-v2 workflow, .github/workflows/release-preparation.yml inlined attacker-controlled github.event.pull_request.title into a run: shell command during the pull_request opened, reopened, and ready_for_review events, so a non-draft fork PR whose title starts with Release v could execute shell commands on the ubuntu-latest runner during the generate-changelog job. This vulnerability is fixed by commit cafc3946059e6337d2089d4fec8b6885ba17c332.
