CERT Polska coordinated disclosure of CVE-2026-33385, a blind SQL injection vulnerability affecting OpenSolution Quick.CMS, discovered in version 6.8 though other versions may be affected. The flaw stems from improper neutralization of input across multiple administration panel fields, allowing an authenticated high-privileged user to inject SQL and bypass front-end validation controls, with potential for database destruction.
Notably, the vendor has declined to remediate the issue, arguing that the administration panel is already designed for users with significant trust and modification capabilities, making the SQL injection a secondary concern within the existing trust model. This is a low-severity disclosure from an exploitation standpoint since it requires existing high-privilege administrative access, but organizations running Quick.CMS should be aware that no patch is forthcoming and should apply compensating controls around admin account access.
