HIGHNVD 8.78.7—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under NVD CVSS v3. EPSS exploit probability: 1.2%, top 36% 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In the git-tag-annotation-action (open source GitHub Action) before version 1.0.1, an attacker can execute arbitrary (*) shell commands if they can control the value of [the tag input] or manage to alter the value of [the GITHUB_REF environment variable]. The problem has been patched in version 1.0.1. If you don't use the tag input you are most likely safe. The GITHUB_REF environment variable is protected by the GitHub Actions environment so attacks from there should be impossible. If you must use the tag input and cannot upgrade to > 1.0.0 make sure that the value is not controlled by another Action.
