All the vulnerabilities related to the version 2.0.5 of the package
Denial of Service in js-yaml
Versions of js-yaml
prior to 3.13.0 are vulnerable to Denial of Service. By parsing a carefully-crafted YAML file, the node process stalls and may exhaust system resources leading to a Denial of Service.
Upgrade to version 3.13.0.
Code Injection in js-yaml
Versions of js-yaml
prior to 3.13.1 are vulnerable to Code Injection. The load()
function may execute arbitrary code injected through a malicious YAML file. Objects that have toString
as key, JavaScript code as value and are used as explicit mapping keys allow attackers to execute the supplied code through the load()
function. The safeLoad()
function is unaffected.
An example payload is
{ toString: !<tag:yaml.org,2002:js/function> 'function (){return Date.now()}' } : 1
which returns the object
{
"1553107949161": 1
}
Upgrade to version 3.13.1.
Arbitrary Code Execution in underscore
The package underscore
from 1.13.0-0 and before 1.13.0-2, from 1.3.2 and before 1.12.1 are vulnerable to Arbitrary Code Execution via the template function, particularly when a variable property is passed as an argument as it is not sanitized.
Regular Expression Denial of Service in underscore.string
Versions of underscore.string
prior to 3.3.5 are vulnerable to Regular Expression Denial of Service (ReDoS).
The function unescapeHTML
is vulnerable to ReDoS due to an overly-broad regex. The slowdown is approximately 2s for 50,000 characters but grows exponentially with larger inputs.
Upgrade to version 3.3.5 or higher.
