CVE-2026-76843
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
Summary
Official Flair wheels for versions 0.15.0 and 0.15.1 still contain flair/models/clustering.py, which executes arbitrary Python code when loading a model. The previous fix for CVE-2024-10073 does not remove this issue from the distributed package.
Risk Assessment
Loading a model supplied by an attacker can execute their code with the privileges of the loading process, potentially leading to full system compromise.
Recommendation
Do not load models from untrusted sources. Update Flair to a version that actually removes this file, or apply a workaround by manually deleting the vulnerable module.

The affected Ebyte product uses a deprecated hashing algorithm in an authentication-related operation. Under conditions where an attacker can manipulate or predict the authentication exchange, the weak construction may reduce the assurance provided by the authentication mechanism and facilitate unauthorized access.
- CVE-2026-73819Critical
The affected Ebyte product's vendor configuration utility permits access to administrative functions without verifying the operator's identity under certain credential conditions. An unauthenticated attacker on the adjacent network could modify critical settings or change access credentials, potentially preventing legitimate administrators from managing the device.

Original NVD description (English source)
The official Flair wheels for 0.15.0 and 0.15.1 still contain flair/models/clustering.py, whose ClusteringModel.load static method returns pickle.loads(joblib.load(str(model_file))) and so executes arbitrary Python while loading a model file. Loading a model supplied by an attacker therefore runs that attacker's code with the privileges of the loading process. This is the same sink and the same file as CVE-2024-10073, which records 0.15.0 as the fixed version on the basis that clustering support was dropped in that release; the module was removed from the documented API but remains present in the distributed artifact and reachable by importing flair.models.clustering directly, so the earlier record's fixed version does not hold for the shipped package.
