Summary
Glances: `--disable-config-exec` does not cover on-alert action commands (incomplete fix of CVE-2026-53925)
Details
Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.6, GlancesActions.run() in glances/actions.py ignores --disable-config-exec for on-alert action commands and invokes secure_popen() with shell operators enabled, allowing configured redirection, command chaining, or pipes to execute when an alert triggers. This issue is fixed in 4.5.6.

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.
