Description

The validation for base64 results into stack overflow error if the size of the incoming string is greater than 3355436 bytes. This was fixed in the PR validatorjs/validator.js#2574 in validator dependency. The new upcoming validator release 13.15.19 is holding the fix. The version of the validator dependency should then be updated after Release PR has been merged and released.

See: validatorjs/validator.js#2573
PR in validator library: validatorjs/validator.js#2574

Minimal code-snippet showcasing the problem

export class FooDto { @IsBase64() someBase64: string // send here a string base64 larger than the above mentioned byte size }

Expected behavior

IsBase64 will succeed even for large base64

Actual behavior

isBase64() causes "RangeError: Maximum call stack size exceeded"
