DescriptionCVE.org

The WP Directory Kit WordPress plugin before 1.5.8 does not sanitize and escape some of its category and location fields before outputting them in page attributes, allowing users with a WP Directory Kit WordPress plugin before 1.5.8-specific listing-management role (and without the unfiltered_html capability) to perform Stored Cross-Site Scripting attacks that execute for any visitor of the affected page.

AnalysisAI

Stored cross-site scripting in the WP Directory Kit WordPress plugin before version 1.5.8 lets an authenticated user who holds the plugin's listing-management role (and who does not have the WordPress unfiltered_html capability) inject script into a listing's category and location fields, which the plugin then prints unescaped inside page attributes; the payload persists and executes for any anonymous visitor who views the affected directory page, requiring no further interaction from the victim. The attacker must already possess that elevated listing-management role and the plugin must be installed with directory listings in active use, so this is a genuine but conditional issue rather than a public-facing injection path. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated account holding the WP Directory Kit plugin's specific listing-management role (a user permitted to create/manage directory listings) that lacks the WordPress unfiltered_html capability; such a user injects script into a listing's category or location fields. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine but conditional stored XSS in the WP Directory Kit WordPress plugin (before 1.5.8), CWE-79. … 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 Upgrade the WP Directory Kit plugin to version 1.5.8 or later; this is the vendor-released patch and the only complete fix, since the flaw is in the plugin's output escaping and cannot be corrected by configuration. … Detailed patch versions, workarounds, and compensating controls in full report.
