Summary

CVE-2026-31922 is a high-severity SQL Injection (CWE-89) vulnerability. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 11.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-31922 is an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability that enables Blind SQL Injection in the Ays Pro Fox LMS (fox-lms) WordPress plugin. This flaw affects Fox LMS versions from n/a through 1.0.6.3 and is classified under CWE-89.

The vulnerability carries a CVSS v3.1 base score of 8.5 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L), indicating high severity. Low-privileged authenticated users (PR:L) can exploit it remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation allows high-impact confidentiality breaches, such as extracting sensitive data via blind SQL techniques, alongside low availability disruption and a scope change (S:C) that amplifies effects.

Mitigation guidance is available in the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/fox-lms/vulnerability/wordpress-fox-lms-plugin-1-0-6-3-sql-injection-vulnerability?_s_id=cve, which details the SQL injection vulnerability in the WordPress Fox LMS plugin version 1.0.6.3.
