Name of the Vulnerable Software and Affected Versions
js-yaml versions 3.0.0 through 3.14.x
js-yaml versions 4.0.0 through 4.2.x
Description
js-yaml can consume quadratic CPU time when parsing a document that grows linearly in size. This occurs when a chain of mappings utilizes merge keys, where each subsequent mapping merges the previous one.
Recommendations
Update js-yaml versions 3.0.0 through 3.14.x to version 3.15.0.
Update js-yaml versions 4.0.0 through 4.2.x to version 4.3.0.
