AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
REST API is network-reachable with no complexity beyond having admin credentials (PR:H); arbitrary call_user_func() yields full C/I/A with no scope change.

The ShopLentor plugin for WordPress is vulnerable to arbitrary function execution via the woolentoropt/v1/custom-action REST API endpoint in all versions up to, and including, 3.3.7. This is due to the handle_action() method passing user-supplied input directly to call_user_func() without an allowlist of permitted callbacks. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute arbitrary PHP callable functions via the 'callback' parameter.
AnalysisAI
Arbitrary PHP function execution in ShopLentor (woolentor-addons) for WordPress up to and including version 3.3.7 allows authenticated administrators to invoke any PHP callable on the server via the woolentoropt/v1/custom-action REST API endpoint. The root cause is the plugin's handle_action() method passing the user-supplied 'callback' parameter directly into PHP's call_user_func() with no allowlist restriction, enabling full server-side code execution under the web server's privilege context. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold an authenticated WordPress session with Administrator-level privileges or higher - confirmed by the CVSS PR:H metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) accurately reflects the technical impact but the PR:H metric is the critical limiting factor in real-world risk: exploitation requires an attacker to already hold WordPress Administrator credentials or higher. … 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 ShopLentor plugin to a version beyond 3.3.7 immediately; an upstream fix has been committed to the WordPress plugin SVN repository (changeset 3504292), though the exact released version number is not independently confirmed from available references - verify the current version in the WordPress plugin directory at https://wordpress.org/plugins/woolentor-addons/ or the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/00138875-d892-460c-b0ce-7a01335d26dc?source=cve before updating. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct an immediate audit of all WordPress administrator accounts for unauthorized access, review server logs for suspicious REST API activity to the /woolentoropt/v1/custom-action endpoint, and revoke credentials for any compromised accounts. …
