CyberRota Analysis

AI-Generated

The vulnerability allows unauthenticated attackers to send an unlimited number of login requests to the POST /v1/sessions endpoint in Plainpad versions up to 1.1.1, due to a missing rate limiting mechanism. This can lead to brute-force attacks, potentially compromising user accounts and causing CPU exhaustion from excessive bcrypt processing. Organizations using affected versions should prioritize patching to mitigate the risk of credential stuffing and denial-of-service attacks.

Original NVD Description

Plainpad through 1.1.1, fixed in commit d3823fc, contains a missing rate limiting vulnerability that allows unauthenticated attackers to send unbounded login requests to the POST /v1/sessions endpoint due to dead code in App\Http\Kernel.php that is never instantiated under the Laravel 11+ skeleton, leaving the API throttle configuration unattached to any route. Attackers can exploit this by sending unlimited credential attempts with no lockout or CAPTCHA enforcement, and additionally trigger CPU exhaustion by forcing repeated bcrypt comparisons on each request.
