CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as problematic has been found in 1Panel-dev MaxKB up to 2.9.0. This affects an unknown part. The manipulation with an unknown input leads to a weak hash vulnerability. CWE is classifying the issue as CWE-328. The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack). This is going to have an impact on confidentiality. The summary by CVE is:

MaxKB is an open-source AI assistant for enterprise. Prior to 2.9.1, user passwords are stored using unsalted MD5 hashes, making them trivially crackable via rainbow tables or GPU-accelerated brute force (hashcat). This vulnerability is fixed in 2.9.1.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-45413 since 05/12/2026. The exploitability is told to be easy.
