CVE-2021-24998: 
WordPress vulnerability analysis and mitigation

The Simple JWT Login WordPress plugin before version 3.3.0 contains a security vulnerability identified as CVE-2021-24998. The vulnerability relates to the plugin's functionality of creating new WordPress user accounts with randomly generated passwords. The issue was discovered and disclosed in October 2021, affecting all versions of the Simple JWT Login plugin prior to version 3.3.0 (WPScan).

The vulnerability stems from the use of PHP's str_shuffle function for password generation. According to PHP's documentation, this function does not generate cryptographically secure values and should not be used for cryptographic purposes. The vulnerability has been assigned a CVSS score of 3.7 (low severity) and is classified as an 'Insufficient Cryptography' issue under CWE-326 (WPScan).

The use of a cryptographically weak random number generator for password generation could potentially lead to predictable or weak passwords for newly created user accounts. This could make it easier for attackers to guess or predict the generated passwords, potentially leading to unauthorized access to user accounts (WPScan).

The vulnerability has been fixed in version 3.3.0 of the Simple JWT Login plugin. Users are advised to upgrade to this version or later to address the security issue (WPScan, WordPress Plugin).
