DescriptionCVE.org

Unauthenticated SQL Injection in WP Directory Kit <= 1.5.4 versions.

AnalysisAI

SQL injection in the WP Directory Kit WordPress plugin (versions 1.5.4 and earlier) lets unauthenticated remote attackers inject arbitrary SQL through unsanitized input, per a Patchstack disclosure carrying a 9.3 CVSS. Because no login is required (PR:N) and the CVSS marks a scope change with high confidentiality impact, an attacker can read sensitive database contents such as user credentials and WordPress secrets. …

Vulnerability AssessmentAI

Exploitation Exploitation requires only that a reachable WordPress site have the WP Directory Kit plugin (version <= 1.5.4) installed and active, exposing the vulnerable directory query parameter to unauthenticated HTTP requests - no valid account, no user interaction, and no non-default configuration are indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals are consistent for an internet-facing, easily exploitable web flaw: CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N indicates a network-reachable, low-complexity attack requiring no authentication or user interaction, and CWE-89 SQLi is a well-understood, frequently automated class. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Update WP Directory Kit to the first release after 1.5.4 that contains the fix as published by the vendor; the input data does not name an exact fixed version, so administrators should consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/wpdirectorykit/vulnerability/wordpress-wp-directory-kit-plugin-1-5-4-sql-injection-vulnerability-2) and the plugin changelog to confirm the patched build before deploying. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: immediately disable or uninstall WP Directory Kit from production environments; if removal is not feasible, implement a Web Application Firewall rule blocking requests to vulnerable endpoints and restrict access to administrator IP ranges only. …
