Unauthenticated Cross Site Scripting (XSS) in LeadConnector <= 4.0.5 versions.
AnalysisAI
Unauthenticated stored or reflected Cross-Site Scripting in the LeadConnector WordPress plugin (versions ≤ 4.0.5) allows remote attackers to inject and execute arbitrary JavaScript in a victim's browser session without any prior authentication. The CVSS vector confirms a scope change (S:C), meaning the injected script escapes the plugin's context and can affect the broader WordPress session environment. …

Vulnerability AssessmentAI
| Exploitation | The CVSS vector (PR:N) confirms exploitation requires no authentication against the WordPress site. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.1 score reflects a network-accessible, low-complexity attack requiring no privileges (PR:N) but needing victim interaction (UI:R), which somewhat limits mass-automated exploitation. … 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 the LeadConnector WordPress plugin to a version above 4.0.5 as the primary remediation; the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/leadconnector/vulnerability/wordpress-leadconnector-plugin-4-0-5-cross-site-scripting-xss-vulnerability should be consulted for the exact patched release version, which was not independently confirmed from the available input data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all WordPress installations to identify any running LeadConnector plugin version 4.0.5 or earlier; disable or completely remove the plugin from affected sites, or deploy web application firewall (WAF) rules to block XSS injection attempts targeting the plugin if immediate removal is not operationally feasible. …
