DescriptionCVE.org

Unauthenticated Insecure Direct Object References (IDOR) in WpEvently <= 5.6.0 versions.

AnalysisAI

Unauthenticated IDOR in the WpEvently WordPress plugin (versions ≤ 5.6.0) allows remote attackers with no credentials to supply user-controlled object identifiers that the plugin resolves without authorization checks, yielding partial integrity and availability impact over event-related data. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation requires only standard network access to a public-facing WordPress installation running the affected plugin. …

Vulnerability AssessmentAI

Exploitation No authentication is required (CVSS PR:N) and no special server-side configuration is needed beyond a publicly accessible WordPress installation running WpEvently ≤ 5.6.0 in its default state. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 6.5 score (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L) reflects genuinely trivial reachability and zero authentication requirements, but the impact ceiling is bounded: there is no confidentiality exposure (C:N), and both integrity and availability impacts are rated Low, meaning an attacker cannot exfiltrate sensitive data or fully disable the service through this vector alone. … 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 WpEvently to the first release beyond 5.6.0 once MagePeople Inc. … Detailed patch versions, workarounds, and compensating controls in full report.
