AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-33289 is an LDAP Injection vulnerability found in the authentication module of SuiteCRM versions prior to 7.15.1 and 8.9.3. The issue occurs because the application does not properly sanitize user-supplied input before embedding it into LDAP search filters.
This improper handling allows an unauthenticated attacker to inject LDAP control characters and manipulate the LDAP query logic.
As a result, the attacker can bypass authentication or gain unauthorized access to sensitive information.
