    Regular Expression Denial of Service (ReDoS)

    ajv is an Another JSON Schema Validator

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper validation of the pattern keyword when combined with $data references. An attacker can cause the application to become unresponsive and exhaust CPU resources by submitting a specially crafted regular expression payload.

    Note:

    This is only exploitable if the $data option is enabled.

    How to fix Regular Expression Denial of Service (ReDoS)?

    There is no fixed version for ajv.

    Prototype Pollution

    ajv is an Another JSON Schema Validator

    Affected versions of this package are vulnerable to Prototype Pollution. A carefully crafted JSON schema could be provided that allows execution of other code by prototype pollution. (While untrusted schemas are recommended against, the worst case of an untrusted schema should be a denial of service, not execution of code.)

    How to fix Prototype Pollution?

    Upgrade ajv to version 6.12.3 or higher.

    <6.12.3
