Summary

CVE-2026-33289 is a high-severity LDAP Injection (CWE-90) vulnerability in Suitecrm Suitecrm. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 48th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-33289 is an LDAP injection vulnerability in the authentication flow of SuiteCRM, an open-source enterprise-ready Customer Relationship Management (CRM) software application. The flaw affects SuiteCRM versions prior to 7.15.1 and 8.9.3, where the application fails to properly sanitize user-supplied input before embedding it into LDAP search filters, allowing injection of LDAP control characters.

An unauthenticated attacker can exploit this vulnerability by manipulating the LDAP query logic during authentication, potentially achieving authentication bypass or information disclosure. The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-90 (Improper Neutralization of Special Elements used in an LDAP Query).

SuiteCRM versions 7.15.1 and 8.9.3 patch this issue. Additional details are available in the release notes at https://docs.suitecrm.com/admin/releases/7.15.x and the GitHub security advisory at https://github.com/SuiteCRM/SuiteCRM/security/advisories/GHSA-26vx-rj47-x599.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover LDAP injection flaws through static analysis or crafted test cases.

SI-10 Information Input Validation good match

Input validation directly stops untrusted data from reaching an LDAP query builder without neutralization of special characters.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require safe query construction and escaping that structurally prevents LDAP injection.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input neutralization and query parameterization to prevent LDAP injection.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches LDAP injection via dynamic analysis or fuzzing, but does not prevent it at the source.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and query construction practices that directly prevent LDAP injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements include explicit rules for safe construction of directory queries, mitigating LDAP injection.

A.8.28 Secure coding partial match
prevents

Secure coding standards require proper neutralization of LDAP special characters, directly eliminating this weakness.

A.8.27 Secure system architecture and engineering principles none match
mitigates

Secure architecture principles encourage safe query interfaces but do not prescribe the specific coding controls needed for LDAP injection.

A.8.3 Information access restriction none match
none

Information access restriction limits who can query LDAP but does not address how queries are built.
