CVE-2026-33289
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 7.15.1 and 8.9.3, an LDAP Injection vulnerability exists in the SuiteCRM authentication flow. The application fails to properly sanitize user-supplied input before embedding it into the LDAP search filter. By injecting LDAP control characters, an unauthenticated attacker can manipulate the query logic, which can lead to authentication bypass or information disclosure. Versions 7.15.1 and 8.9.3 patch the issue.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSuiteCRM versions prior to 7.15.1 and 8.9.3 contain an LDAP injection vulnerability in the authentication flow where user-supplied input is not properly sanitized before being embedded in LDAP search filters. An unauthenticated attacker can inject LDAP control characters to manipulate query logic, potentially bypassing authentication or disclosing sensitive information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SuiteCRM versionLocate the version file or admin panel in your SuiteCRM installation and record the exact version numberAffected if the installed version is below 7.15.1, or is 8.0.0 through 8.9.2 inclusive
-
Confirm LDAP authentication is in useCheck your SuiteCRM configuration files or authentication settings to determine if LDAP authentication is enabled and configuredAffected if LDAP authentication is not enabled - the vulnerability only applies to environments using LDAP for user authentication
-
Review LDAP filter implementationExamine the LDAP query code in the authentication module for proper escaping of user-supplied input before embedding in search filtersAffected if user-provided parameters are used directly in LDAP search filters without escaping LDAP special characters (such as * ( ) \ NUL)
-
Compare version to affected rangesDocument your exact SuiteCRM version and confirm it falls outside the fixed versions 7.15.1+ and 8.9.3+Affected if your version is below 7.15.1 or between 8.0.0 and 8.9.2 inclusive and you use LDAP authentication
You are affected if your SuiteCRM version is less than 7.15.1 or between 8.0.0 and 8.9.2 AND LDAP authentication is enabled in your environment.

dbcve · scoped7.15.18.9.3
Upgrade to SuiteCRM version 7.15.1 or 8.9.3 or later. If immediate upgrade is not possible, implement proper input validation and LDAP filter escaping for all user-supplied parameters used in LDAP queries.
SuiteCRM 7.15.1 (for 7.x branch) or SuiteCRM 8.9.3 (for 8.x branch)
- 1. Identify the currently installed SuiteCRM version by checking the version file or admin interface.
- 2. For SuiteCRM 7.x versions (< 7.15.1): Upgrade to version 7.15.1 or later.
- 3. For SuiteCRM 8.x versions (>= 8.0.0, < 8.9.3): Upgrade to version 8.9.3 or later.
- 4. Download the appropriate upgrade package from the official SuiteCRM repository (github.com/salesagility/SuiteCRM) or the official SuiteCRM website.
- 5. Before upgrading, perform a complete backup of the database and files.
- 6. Follow the standard SuiteCRM upgrade procedure: disable scheduled jobs, clear cache, run the upgrade, and verify functionality.
- 7. After upgrade, verify that LDAP authentication still functions correctly and test for any regressions.
