Summary

CVE-2024-8529 is a critical-severity SQL Injection (CWE-89) vulnerability in Thimpress Learnpress. Its CVSS base score is 10.0 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 4% of CVEs by exploit likelihood; 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.

Deeper analysis AI-assisted summary

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

The LearnPress WordPress LMS Plugin is vulnerable to SQL injection in all versions through 4.2.7. The flaw exists in the /wp-json/lp/v1/courses/archive-course REST API endpoint, where the c_fields parameter is concatenated into an SQL query without adequate escaping or the use of prepared statements, allowing an attacker to alter the query structure.

Unauthenticated attackers can supply crafted input to this endpoint and append arbitrary SQL clauses, enabling extraction of sensitive data from the WordPress database. The vulnerability carries a CVSS 3.1 score of 10.0, reflecting network-accessible exploitation with no authentication or user interaction required and full impact on confidentiality, integrity, and availability.

A fix is available in version 4.2.7.1, as indicated by the plugin's changelog and the Wordfence advisory. Public analysis of the issue, including proof-of-concept details, has been published at abrahack.com. The EPSS score stands at 0.7569 with no material increase from its peak.

Vulnerability Data

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to SQL Injection via the 'c_fields' parameter of the /wp-json/lp/v1/courses/archive-course REST API endpoint in all versions up to, and including, 4.2.7 due to insufficient escaping on the user supplied…

parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Mitigating Controls (NIST 800-53 r5) AI

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

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

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

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

PR.PS-06 mostly match
prevents

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
prevents

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.

finds

The same secure-coding and static-analysis activities surface missing neutralization of SQL metacharacters before the system is accepted.

prevents

Early warnings and shared best-practice information help organizations apply the latest remediation techniques against SQL-injection vulnerabilities.

prevents

Threat-intelligence feeds that surface new SQL-injection campaigns enable rapid updates to query-construction defenses and detection signatures before exploitation occurs.

prevents

Secure-coding rules and security testing phases mandate the use of parameterized queries or equivalent escaping, preventing the construction of dynamic SQL statements from untrusted input.

prevents

Language-specific secure coding rules, peer review and SAST together prevent the construction of SQL statements from untrusted data without proper parameterization or escaping.
