What it detects
yaml.load() without SafeLoader: an injection check run by the semgrep analyzer.
Evidence
The Semgrep source location, rule identity, and bounded match context normalized into Fendix evidence.
Remediation
yaml.load() without yaml.SafeLoader can execute arbitrary Python code via the !!python/object tag. Use yaml.safe_load() or pass Loader=yaml.SafeLoader explicitly.
Limitations
This check is limited to the applicability and evidence delivered by semgrep. Review the evidence in context; a match is a finding input, while confidence and policy determine its disposition.
