CVE-2026-13228: CWE-269 Improper Privilege Management in latepoint LatePoint – Calendar Booking Plugin for Appointments and Events
The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Privilege Escalation to Administrator in versions up to, and including, 5.6.3 This is due to an Insecure Direct Object Reference (IDOR) in the create_or_update() function of OsOrdersController, which allows an authenticated Agent to supply an arbitrary order[customer_id] and overwrite any LatePoint customer's email field (including one linked to a WordPress Administrator's account) through the public-scope customer set_data() call, combined with a missing role verification in OsAuthHelper::authorize_customer() which logs in the linked WordPress user without checking its role. This makes it possible for authenticated attackers, with custom (Agent)-level access and above, to elevate their privileges to Administrator.
AI Analysis
Technical Summary
CVE-2026-13228 describes a privilege escalation vulnerability in the LatePoint – Calendar Booking Plugin for Appointments and Events for WordPress. The flaw arises from an insecure direct object reference in the create_or_update() function of OsOrdersController, permitting an authenticated Agent to specify an arbitrary order[customer_id] and overwrite the email field of any LatePoint customer, including those tied to WordPress Administrator accounts. Additionally, the OsAuthHelper::authorize_customer() function lacks proper role verification when logging in the linked WordPress user, enabling attackers with Agent-level access to escalate their privileges to Administrator.
Potential Impact
Successful exploitation allows an authenticated user with Agent-level privileges to escalate to full Administrator access on the WordPress site. This can lead to complete site compromise, including control over content, user accounts, and potentially the underlying server environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Agent-level user access and monitor for suspicious activity related to customer email modifications. Avoid granting Agent-level access to untrusted users.
