This vulnerability in YMC Filter (versions <=3.11.5) is due to improper neutralization of special elements used in SQL commands, classified as CWE-89 (SQL Injection). It allows remote attackers to inject SQL code without authentication or user interaction, potentially compromising confidentiality and causing partial denial of service. The CVSS 3.1 base score is 9.3 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L). No vendor advisory or patch information is available, and the product is not a cloud service. The vulnerability is published and known but without an official remediation level.

Successful exploitation could allow remote attackers to execute arbitrary SQL commands on the backend database, leading to a complete compromise of data confidentiality and partial impact on availability. Integrity impact is not indicated. The vulnerability requires no privileges and no user interaction, making it highly severe.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or workaround is currently provided, users should monitor vendor communications for updates. Until a patch is available, consider restricting network access to the affected application and applying any available input validation or web application firewall rules to mitigate SQL injection risks.
