A missing authorization flaw in the Marketing Fire Editorial Calendar plugin for WordPress poses a high risk of unauthorized access due to improper access control enforcement.

This vulnerability is classified as CWE-862: Missing Authorization, occurring because the plugin fails to perform adequate capability checks on administrative functions. Based on the CVSS vector (PR:L), this flaw requires an authenticated user with low privileges to trigger the unauthorized actions.

Successful exploitation of this vulnerability allows authenticated users to perform actions they are not authorized to execute, potentially leading to unauthorized data modification or administrative configuration changes. With a CVSS score of 8.1, the risk is classified as High, reflecting the significant potential for integrity compromise within the editorial workflow.

Immediate Action: As no specific patch version is currently identified, users should monitor the official Patchstack vulnerability database and the WordPress plugin repository for an update that addresses this access control deficiency. If an update is not immediately available, consider temporarily deactivating the plugin if it is not business-critical.

Proactive Monitoring: Review WordPress access logs for anomalous activity originating from low-privileged user accounts, specifically monitoring for unusual plugin configuration changes or unauthorized content modifications.

Compensating Controls: Implement a Web Application Firewall (WAF) to filter suspicious requests that attempt to access restricted administrative endpoints within the editorial-calendar plugin path.

Public Exploit Available: Unknown.

Given the High severity rating, administrators must prioritize the security of their WordPress environment by restricting access to the Editorial Calendar plugin to trusted users only. Once a vendor update is released, apply the patch immediately to remediate the underlying authorization failure and prevent potential privilege escalation or unauthorized system modifications.
