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 vulnerability CVE-2023-0631 is an SQL injection issue tracked as CWE-89 in the Paid Memberships Pro WordPress plugin prior to version 2.9.12. The root cause is insufficient protection that allows shortcodes to concatenate user-controlled attributes directly into SQL queries.

Authenticated subscribers can exploit the flaw over the network with low complexity and no user interaction required, enabling them to read, modify, or delete arbitrary database contents and achieve complete compromise of confidentiality, integrity, and availability.

References published by WPScan describe the affected shortcode paths and indicate that the issue is resolved by upgrading to version 2.9.12 or later.

EPSS for the CVE rose from lower values to a peak of 0.8013 on 2026-02-03 before receding to the current score of 0.5968, indicating post-disclosure exploitation interest that warrants renewed attention.

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.
