Detailsinfo

A vulnerability classified as critical was found in immich-app Immich up to 3.2.x. Affected by this vulnerability is the function clear_cache of the file machine-learning/immich_ml/models/base.py of the component Predict Endpoint. The manipulation of the argument cache_dir with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect integrity, and availability. The summary by CVE is:

Immich is a high-performance self-hosted photo and video management solution. Prior to 3.3.0, the unauthenticated machine-learning /predict endpoint in machine-learning/immich_ml/main.py accepted an options object and passed its values into model construction in machine-learning/immich_ml/models/base.py without restricting security-sensitive parameters. An attacker with network access to the service could set cache_dir to an arbitrary writable path, causing model downloads to write there and causing clear_cache() to pass that path to shutil.rmtree() after selected model-loading failures. Depending on filesystem permissions and the selected path, this could modify files in mounted data locations or recursively delete an attacker-selected directory. The model-name allowlist prevents this issue from becoming arbitrary-model deserialization or code execution. This issue is fixed in version 3.3.0.

It is possible to read the advisory at github.com. This vulnerability is known as CVE-2026-119328 since 10/29/2026. The exploitation appears to be easy. The attack can be launched remotely.
