CVE intelligence and bounded remediation

CVE-2022-2846 — Dwbooster Calendar Event Multi View security vulnerability

Medium CVSS 4.3

The Calendar Event Multi View WordPress plugin before 1.4.07 does not have any authorisation and CSRF checks in place when creating an event, and is also lacking sanitisation as well as escaping in some of the event fields. This could allow unauthenticated attackers to create arbitrary events and put Cross-Site Scripting payloads in it.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
