DescriptionCVE.org

The RegistrationMagic WordPress plugin before 6.0.9.4 does not sanitise and escape a parameter before using it in a SQL statement, which could allow high privilege users such as admin to perform SQL injection attacks.

AnalysisAI

SQL injection in the RegistrationMagic WordPress plugin (all versions before 6.0.9.4) permits authenticated administrators to inject arbitrary SQL through an unsanitized parameter. The CVSS Scope:Changed metric indicates the injected query can reach beyond the WordPress application boundary into the underlying database layer, enabling cross-schema data reads. …

Vulnerability AssessmentAI

Exploitation Exploitation requires possession of a valid WordPress administrator account (PR:H per CVSS vector) - low-privilege subscribers, editors, or contributors cannot trigger this vulnerability. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS base score of 4.1 is calibrated by the PR:H requirement - exploitation is gated behind valid WordPress administrator credentials, substantially narrowing the realistic attacker population. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained WordPress administrator credentials - through phishing, credential stuffing, or a separate compromise - authenticates to the WordPress admin panel and submits a crafted request to the RegistrationMagic plugin containing a SQL injection payload in the vulnerable parameter. The unsanitized value is passed directly into a database query, allowing the attacker to execute UNION-based or blind SQL injection techniques to extract WordPress database contents or, given the Scope:Changed rating, data from other schemas on the same database server. …
Remediation Update the RegistrationMagic WordPress plugin to version 6.0.9.4 or later using the standard WordPress plugin update interface or the plugin repository; this is the vendor-released patch per advisory data. … Detailed patch versions, workarounds, and compensating controls in full report.
