Security readout for executives and security teams
Plain-English summary
Editorial Calendar for WordPress versions 2.0 through 2.6 allowed authenticated remote users to influence database queries through calendar date parameters. A successful SQL injection could expose or change site data or disrupt availability. Version 2.7 contains the referenced fix; prioritize sites that still run affected versions.
Executive priority
Prioritize remediation during the next WordPress maintenance window, sooner for sites with many content users or external contributors. The risk is meaningful because SQL injection can affect data, but urgency is moderated by required authentication and no sourced evidence of active exploitation.
Technical view
The issue is CWE-89 SQL injection in edcal_filter_where within edcal.php. The vulnerable inputs are edcal_startDate and edcal_endDate. The provided CVSS v2 vector is AV:N/AC:L/Au:S/C:P/I:P/A:P, indicating network reachability, low complexity, required authentication, and partial confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress sites running Editorial Calendar Plugin versions 2.0 through 2.6. The CVSS vector indicates authentication is required, so public internet exposure matters most where untrusted or low-privilege accounts can access the vulnerable functionality.
Exploitation context
The source bundle says the attack can be launched remotely and requires authentication. It does not identify active exploitation, and CISA KEV status is false. Treat exploit availability or in-the-wild use as unconfirmed from these sources.
Researcher notes
Focus on version verification, reachable roles, and whether the vulnerable filter path is accessible to non-administrative users. The bundle identifies the vulnerable parameters and patch but does not provide complete exploitation prerequisites beyond remote authenticated access.
Mitigation direction
- Upgrade Editorial Calendar Plugin to version 2.7 or later.
- Confirm the referenced patch a9277f13781187daee760b4dfd052b1b68e101cc is present.
- Disable or remove the plugin if upgrade cannot be completed promptly.
- Review vendor or project guidance before applying alternative mitigations.
- Restrict WordPress accounts that can access editorial calendar functionality.
Validation and detection
- Inventory WordPress sites for Editorial Calendar Plugin installations.
- Confirm installed plugin versions are not 2.0 through 2.6.
- Check whether edcal.php includes the patched handling for date parameters.
- Review application and database logs for suspicious calendar date parameter activity.
- Validate remediation in staging before production rollout.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
