All the vulnerabilities related to the version 1.1.11 of the package
Regular Expression Denial of Service (ReDoS)
npm ssri 5.2.2-6.0.1 and 7.0.0-8.0.0, processes SRIs using a regular expression which is vulnerable to a denial of service. Malicious SRIs could take an extremely long time to process, leading to denial of service. This issue only affects consumers using the strict option.
Cross-Site Scripting in serialize-javascript
Versions of serialize-javascript prior to 2.1.1 are vulnerable to Cross-Site Scripting (XSS). The package fails to sanitize serialized regular expressions. This vulnerability does not affect Node.js applications.
Upgrade to version 2.1.1 or later.
Insecure serialization leading to RCE in serialize-javascript
serialize-javascript prior to 3.1.0 allows remote attackers to inject arbitrary code via the function "deleteFunctions" within "index.js".
An object such as {"foo": /1"/, "bar": "a\"@__R-<UID>-0__@"} was serialized as {"foo": /1"/, "bar": "a\/1"/}, which allows an attacker to escape the bar key. This requires the attacker to control the values of both foo and bar and guess the value of <UID>. The UID has a keyspace of approximately 4 billion making it a realistic network attack.
