Summary

CVE-2026-34018 is a medium-severity SQL Injection (CWE-89) vulnerability in Cubecart Cubecart. Its CVSS base score is 5.1 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Compromise Infrastructure (T1584); ranked at the 24th 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-2026-34018 is an SQL injection vulnerability (CWE-89) in CubeCart versions prior to 6.6.0. The flaw allows an attacker to execute arbitrary SQL statements on the product, earning a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical due to its high impacts across confidentiality, integrity, and availability.

The vulnerability can be exploited by any unauthenticated attacker with network access, requiring low complexity and no user interaction. Successful exploitation enables arbitrary SQL execution, potentially allowing data exfiltration, modification, deletion, or denial of service on the underlying database.

Mitigation is addressed in CubeCart 6.6.0, released as described in the official community announcement, which notes it as the biggest update in years. The Japanese Vulnerability Notes advisory (JVN#78422311) provides further details on the issue and recommended actions.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover SQLi flaws before deployment but does not stop their introduction.

SI-10 Information Input Validation good match

Input validation directly stops untrusted data from reaching SQL query construction without neutralization.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require parameterized queries and input sanitization that structurally eliminate SQLi.

SI-4 System Monitoring partial match

System monitoring can identify attempted SQLi exploitation via anomalous queries after the weakness exists.

PR.PS-06 mostly match
blocks

Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.

PR.AT-02 partial match
blocks

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.
