GHSA-Q84H-WR78-498W

Vulnerability from github – Published: 2026-08-19 15:32 – Updated: 2026-08-19 15:32

Details

stigmem-node 0.9.0a1 allows plugin signature enforcement to be disabled via a single configuration flag without a second explicit acknowledgment. If that setting is carried into an environment where plugin directories are writable by less-trusted users, unsigned (potentially malicious) plugin code could be loaded and executed, resulting in arbitrary code execution. Fixed in 0.9.0a2, which requires a second explicit acknowledgment to disable signature enforcement.

Severity

7.3 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
