js-yaml is a human-friendly data serialization language.
Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity in the storeMappingPair() function in loader.js when handling repeated aliases in merge sequences. An attacker can exhaust CPU resources and significantly degrade service availability by submitting malicious YAML documents.
prismjs is a lightweight, robust, elegant syntax highlighting library.
Affected versions of this package are vulnerable to Arbitrary Code Injection via the document.currentScript lookup process. An attacker can manipulate the web page content and execute unintended actions by injecting HTML elements that overshadow legitimate DOM elements.
