DescriptionCVE.org

The JS Help Desk WordPress plugin before 3.1.4 grants a support-agent capability to the Contributor role on activation and does not perform a capability check on a user-listing handler, allowing Contributor-level users to enumerate the email addresses of all registered WordPress users.

AnalysisAI

User email enumeration in the JS Help Desk WordPress plugin (versions before 3.1.4) allows any Contributor-level site user to harvest the email addresses of all registered WordPress users. Two design flaws compound: the plugin unconditionally grants a support-agent capability to the built-in Contributor role at activation time, and the user-listing handler omits any capability check entirely, making the Contributor elevation the effective attack precondition. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid Contributor-level (or higher) WordPress account on the target site. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The NVD-assigned CVSS 3.1 score of 6.5 with vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N is well-calibrated: network exploitability with low complexity and Contributor-level authentication yielding full confidentiality compromise of the user roster is accurately characterized as Medium-High. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker registers a free Contributor account on a WordPress site running the vulnerable plugin (or uses an existing Contributor credential) and directly invokes the unprotected user-listing endpoint - an AJAX action or REST route exposed by JS Help Desk. Because the plugin granted support-agent capability to Contributors at activation, the request passes any role gate, and the handler returns the full list of registered user email addresses with no further authentication required. …
Remediation Update the JS Help Desk WordPress plugin to version 3.1.4 or later, which is the vendor-released patch addressing both the improper support-agent capability grant at activation and the missing capability check on the user-listing handler. … Detailed patch versions, workarounds, and compensating controls in full report.
