Grafana vulnerability

CVSS
8.1
EPSS
4.0%
EPSS pct
90th
Exploited
No known
The `Release PR Merged` workflow in the github repo taosdata/grafanaplugin is subject to a command injection vulnerability which allows for arbitrary code execution within the github action context due to the insecure usage of `${{ github.event.pull_request.title }}` in a bash command within the GitHub workflow. Attackers can inject malicious commands which will be executed by the workflow. This happens because `${{ github.event.pull_request.title }}` is directly passed to bash command on like 25 of the workflow. This may allow an attacker to gain access to secrets which the github action has access to or to otherwise make use of the compute resources.
