All the vulnerabilities related to the version 1.6.2 of the package
Reverse Tabnabbing in showdown
Versions of showdown
prior to 1.9.1 are vulnerable to Reverse Tabnabbing. The package uses target='_blank'
in anchor tags, allowing attackers to access window.opener
for the original page when opening links. This is commonly used for phishing attacks.
Upgrade to version 1.9.1 or later.
yargs-parser Vulnerable to Prototype Pollution
Affected versions of yargs-parser
are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object
, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --foo.__proto__.bar baz'
adds a bar
property with value baz
to all objects. This is only exploitable if attackers have control over the arguments being passed to yargs-parser
.
Upgrade to versions 13.1.2, 15.0.1, 18.1.1 or later.
