Summary
CVE-2023-30628 is a high-severity OS Command Injection (CWE-78) vulnerability in Kiwitcms Kiwi Tcms. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 11% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Kiwi TCMS, an open source test management system, contains a command-injection vulnerability in the changelog.yml GitHub Actions workflow. The flaw affects kiwitcms/Kiwi and kiwitcms/enterprise versions 12.2 and earlier and stems from unsafe use of the attacker-controlled github.head_ref field, which is interpolated directly into a shell command without sanitization, corresponding to CWE-78.
An authenticated user with write access to the repository can supply a malicious branch name such as zzz";echo${IFS}"hello";# in a pull request. Because the workflow runs with unrestricted permissions, this input results in arbitrary command execution on the GitHub Actions runner, enabling the attacker to read repository secrets, modify code, or perform other actions within the CI environment.
The project addressed the issue in commit 834c86dfd1b2492ccad7ebbfd6304bfec895fed2 for Kiwi and commit e39f7e156fdaf6fec09a15ea6f4e8fec8cdbf751 for Enterprise. The accompanying GitHub Security Advisory and the referenced GitHub Actions hardening guidance recommend avoiding untrusted inputs in workflow expressions and switching to safer alternatives such as github.event.pull_request.head.sha.
The EPSS score has remained flat at 0.1286 with no material increase after disclosure.

Vulnerability Data
Kiwi TCMS is an open source test management system. In kiwitcms/Kiwi v12.2 and prior and kiwitcms/enterprise v12.2 and prior, the `changelog.yml` workflow is vulnerable to command injection attacks because of using an untrusted `github.head_ref` field. The `github.head_ref` value is an…

attacker-controlled value. Assigning the value to `zzz";echo${IFS}"hello";#` can lead to command injection. Since the permission is not restricted, the attacker has a write-access to the repository. Commit 834c86dfd1b2492ccad7ebbfd6304bfec895fed2 of the kiwitcms/Kiwi repository and commit e39f7e156fdaf6fec09a15ea6f4e8fec8cdbf751 of the kiwitcms/enterprise repository contain a fix for this issue.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
