CVE-2026-76833 @cgauge/yaml npm Package Arbitrary Code Execution via eval() YAML Tag

@cgauge/yaml npm package contains an arbitrary code execution vulnerability that allows attackers to execute arbitrary JavaScript by embedding a custom !js YAML tag whose construct callback unconditionally calls eval on attacker-supplied string values during document parsing. Any application...
