CVE-2026-29103 Vulnerability Summary

CVE-2026-29103: SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. A Critical Remote Code Execution (RCE) vulnerability exists in SuiteCRM 7.15.0 and 8.9.2, allowing authenticated administrators to execute arbitrary system commands. This vulnerability is a direct Patch Bypass of CVE-2024-49774. Although the vendor attempted to fix the issue in version 7.14.5, the underlying flaw in ModuleScanner.php regarding PHP token parsing remains. The scanner incorrectly resets its internal state ($checkFunction flag) when encountering any single-character token (such as =, ., or ;). This allows attackers to hide dangerous function calls (e.g., system(), exec()) using variable assignments or string concatenation, completely evading the MLP security controls. Versions 7.15.1 and 8.9.3 patch the issue.

Assessing the Risk of CVE-2026-29103

Access Complexity Graph

The exploitability of CVE-2026-29103 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-29103

The exploitability of CVE-2026-29103 is influenced by multiple factors. Security teams should analyze system configurations and apply appropriate countermeasures to mitigate threats.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-29103, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2026-29103, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: High
    Exploiting CVE-2026-29103 can result in unauthorized access to sensitive data, severely compromising data privacy.
  • Integrity: High
    CVE-2026-29103 could allow unauthorized modifications to data, potentially affecting system reliability and trust.
  • Availability: High
    CVE-2026-29103 can disrupt system operations, potentially causing complete denial of service (DoS).
