Lifecycle Timeline
4DescriptionCVE.org
The LearnPress WordPress plugin before 4.0.3 does not perform any authorization check on one of its REST endpoints in all versions up to, and including, 4.0.2, allowing unauthenticated attackers to disclose the payment status of arbitrary orders by enumerating order identifiers.
AnalysisAI
LearnPress WordPress plugin versions up to and including 4.0.2 expose order payment status data through an unauthenticated REST endpoint that omits authorization checks entirely. The CVSS vector (PR:N/AC:L/AV:N) confirms remote unauthenticated exploitation with no preconditions, and SSVC flags the attack as automatable - meaning scripted enumeration of order identifiers at scale is trivially achievable. …

Vulnerability AssessmentAI
| Exploitation | No authentication is required - the CVSS vector PR:N confirms unauthenticated access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.3 Medium score is consistent with the described impact: AV:N/AC:L/PR:N/UI:N confirms remote unauthenticated exploitation with no interaction, but S:U/C:L/I:N/A:N limits the blast radius to partial confidentiality loss only. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends automated GET requests to the LearnPress REST endpoint, iterating over integer order identifiers starting from 1. For each valid ID, the endpoint returns the payment status (e.g., completed, pending, failed), allowing the attacker to reconstruct the site's order history and volume without any credentials. … |
| Remediation | Vendor-released patch: LearnPress 4.0.3, which introduces proper authorization controls on the affected REST endpoint. … Detailed patch versions, workarounds, and compensating controls in full report. |
