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 issue stems from an Insecure Direct Object Reference (IDOR) in the create_or_update() function of OsOrdersController, allowing an authenticated Agent to supply arbitrary customer IDs and overwrite any customer's email, including those linked to WordPress Administrator accounts. Additionally, the OsAuthHelper::authorize_customer() function logs in the linked WordPress user without verifying their role, enabling attackers with Agent-level access to escalate privileges to Administrator. The vulnerability affects versions up to and including 5.6.3. No official patch or remediation level has been published yet.
Potential Impact
An authenticated attacker with Agent-level access can escalate their privileges to Administrator by exploiting the IDOR vulnerability to overwrite administrator email fields and bypass role verification during login. This leads to full administrative control over the WordPress site, compromising confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Agent-level user access and monitor for suspicious activity related to customer data modifications and unauthorized privilege escalations.
