Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input via the cookie jar process. An attacker can cause the client to ignore all remaining valid cookies in the cookie file by inducing it to store an oversized cookie, which leads to aborting the parsing of the cookie file during subsequent operations.
