Several soundness issues have been reported. Resolving them doesn't seem to be considered a priority. In particular, unprincipled use of mutable statics is pervasive throughout the library, making it possible to cause use-after-free in safe code. Currently, no fixed version is available.

### Summary The vulnerability allows an attacker to inject a malicious script into the context of a web page, which can lead to data theft, unauthorized actions on behalf of the user, and other attacks. ### Details The vulnerability is reproducible when sending a properly formatted request to the `POST /projects/upload-example/` endpoint. In the source code, the vulnerability is located at `label_studio/projects/views.py`. ```python 39: @require_http_methods(['POST']) 40: def upload_example_using_config(request): 41: """Generate upload data example by config only""" 42: config = request.POST.get('label_config', '') 43: 44: org_pk = get_organization_from_request(request) 45: secure_mode = False 46: if org_pk is not None: 47: org = generics.get_object_or_404(Organization, pk=org_pk) 48: secure_mode = org.secure_mode 49: 50: try: 51: Project.validate_label_config(config) 52: task_data, _, _ = get_sample_task(config, secure_mode) 5...

### Summary A user on the website can modify any private field on their own state. ### Details An event meant to modify client side storage had access to modify any field on the state for the given user. This includes non-client side ones and most importantly private fields. This still requires the actor to guess the name for the private fields. ### Impact If one of the States in your app can be modified to allow the user into a different role or a different user this allows the actor to act as someone else or as admin.

### Summary Using a constructed (camera) device path with the `config/add`/`add_camera` motionEye web API allows an attacker with motionEye admin user credentials to execute any UNIX shell code within a non-interactive shell as executing user of the motionEye instance, `motion` by default. #### function call stack 1. `post` 2. `add_camera` 3. `config.add_camera` 4. `v4l2ctl.list_resolutions` 5. `utils.call_subprocess` 6. `subprocess.run` ### PoC #### build ```sh RUN_USER="user" RUN_UID=$(id -u ${RUN_USER}) RUN_GID=$(id -g ${RUN_USER}) TIMESTAMP="$(date '+%Y%m%d-%H%M')" docker build \ --network host \ --build-arg="RUN_UID=${RUN_UID?}" \ --build-arg="RUN_GID=${RUN_GID?}" \ -t "${USER?}/motioneye:${TIMESTAMP}" \ --no-cache \ -f docker/Dockerfile . ``` #### reproduce Run: ```sh docker run --rm -d -p 8765:8765 --hostname="motioneye" -v /etc/localtime:/etc/localtime:ro -v /tmp/motioneyeconfig:/etc/motioneye -v /tmp/motioneyeconfig:/var/lib/motioneye ``` ```console ...

### Impact A admin user can upload SVG which may load external data via XML DOM library, specially this can be used for eventually reference none secure XML External Entity References. ### Patches The problem has not been patched yet. Users should upgrade to patched versions once they become available. Currently affected versions are: - 2.6.9 - 2.5.25 - 3.0.0-alpha3 ### Workarounds Patch the effect file `src/Sulu/Bundle/MediaBundle/FileInspector/SvgFileInspector.php` in sulu with: ```diff -$dom->loadXML($svg, \LIBXML_NOENT | \LIBXML_DTDLOAD); +$dom->loadXML($data, LIBXML_NONET); ``` ### References - GitHub repository: https://github.com/sulu/sulu - Vulnerable code: https://github.com/sulu/sulu/blob/2.6/src/Sulu/Bundle/MediaBundle/FileInspector/SvgFileInspector.php

### Impact Applications that use undici to implement a webhook-like system are vulnerable. If the attacker set up a server with an invalid certificate, and they can force the application to call the webhook repeatedly, then they can cause a memory leak. ### Patches This has been patched in https://github.com/nodejs/undici/pull/4088. ### Workarounds If a webhook fails, avoid keep calling it repeatedly. ### References Reported as: https://github.com/nodejs/undici/issues/3895
