DescriptionCVE.org

The Easy Appointments WordPress plugin through 3.12.26 does not verify ownership or capability when returning stored customer details, allowing users with subscriber-level access to read any customer's personal information by iterating an identifier.

AnalysisAI

Insecure direct object reference in the Easy Appointments WordPress plugin (all versions through 3.12.26) permits any authenticated subscriber-level user to retrieve personal information belonging to any appointment booking customer by iterating a customer identifier. The plugin fails to enforce ownership or capability checks before returning stored customer records, exposing PII across the entire customer base to the lowest-privileged WordPress role. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires a WordPress account with at minimum subscriber-level access (PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 4.3 Medium score with vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N accurately characterises the attack surface: network-reachable, low complexity, but gated behind subscriber-level authentication. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	A publicly available exploit exists via WPScan. An attacker self-registers a free subscriber account on any WordPress site running Easy Appointments ≤ 3.12.26 with open registration enabled, then issues a series of authenticated HTTP requests to the plugin's customer-detail endpoint, incrementing the customer ID parameter with each request. …
Remediation	No vendor-released patch has been independently confirmed at time of analysis - all versions through 3.12.26 remain vulnerable. … Detailed patch versions, workarounds, and compensating controls in full report.
