CVE-2026-93484 is a high-severity vulnerability in Znuny that allows for SQL injection, potentially leading to data theft, modification, or service disruption. Users of affected versions should prioritize patching and verification efforts.

• Potential data theft or modification
• Possible denial of service due to database manipulation
• Need for verification of affected versions and exposure
• Priority for patching and remediation efforts

Technical summary

The vulnerability exists in the TicketSearch and ArticleSearchIndex::DB functions of Znuny, where user-supplied input is directly concatenated into SQL queries without proper sanitization. This allows attackers to inject arbitrary SQL commands, potentially leading to data theft, modification, or denial of service. The issue affects Znuny versions prior to 6.5.25 and 7.3.7, and users of affected versions should prioritize patching to mitigate potential risks. The vulnerability is particularly concerning as it enables attackers to inject malicious SQL commands, potentially leading to data theft, modification, or service disruption.
