AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated network reach via publicly emitted nonce gives AV:N/AC:L/PR:N/UI:N, but parameterless-only function calls limit impact to partial disclosure and disruption, so C:L/I:N/A:L rather than full high impact.

Lifecycle Timeline
2DescriptionCVE.org
The Customer Support Ticket System & Helpdesk plugin for WordPress is vulnerable to Code Injection via the 'path' parameter in all versions up to, and including, 6.0.5 due to the use of dynamic function invocation on an attacker-controlled value with insufficient validation. This makes it possible for unauthenticated attackers to invoke arbitrary parameterless PHP functions, which can be used to disrupt site functionality or expose sensitive information. The required nonce is publicly emitted via wp_localize_script whenever the plugin's [emd_form] shortcode is rendered on any public-facing page, making the endpoint reachable by unauthenticated visitors without any prior authentication or privilege.

AnalysisAI
Code injection in the emarket-design Customer Support Ticket System & Helpdesk (WP-Ticket) WordPress plugin, versions up to and including 6.0.5, lets unauthenticated visitors invoke arbitrary parameterless PHP functions through the 'path' parameter, enabling information disclosure or denial of site functionality. Exploitation is reachable without login because the required WordPress nonce is publicly emitted via wp_localize_script wherever the [emd_form] shortcode is rendered, neutralizing the nonce as an access control. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the plugin's [emd_form] shortcode be rendered on at least one public-facing page, because that is what causes the required nonce to be emitted publicly via wp_localize_script - with that condition met, the endpoint is reachable by unauthenticated visitors with no login or privilege. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The published CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, 9.8) reflects unauthenticated, low-complexity network reach - consistent with the description, since the nonce is publicly exposed and no privilege or user interaction is needed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker visits any public page rendering the plugin's [emd_form] shortcode, reads the nonce that wp_localize_script exposes in the page source, then submits a crafted request setting the 'path' parameter to a parameterless PHP function name. The plugin invokes that function dynamically, letting the unauthenticated attacker trigger information disclosure or disrupt site functionality. … |
| Remediation | Upstream fix available (commit/changeset 3617122 in the wp-ticket repository); a released patched version number is not independently confirmed from the provided data, so administrators should update to the latest available release above 6.0.5 as published on the WordPress.org plugin page and verify the version includes the fixed common-functions.php/emd-form-frontend.php code paths. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Verify whether WP-Ticket plugin is installed on production WordPress instances and immediately disable or deactivate the plugin to eliminate attack surface. …
