Security readout for executives and security teams
Plain-English summary
CVE-2023-7306 lets unauthenticated attackers delete arbitrary WordPress posts on sites running vulnerable Frontend File Manager Plugin versions up to and including 21.5. The business risk is content loss, reputational damage, and operational disruption, not data theft based on the supplied CVSS.
Executive priority
Prioritize remediation for public WordPress sites because an unauthenticated attacker could remove content without needing an account. Treat this as a high business integrity risk, especially for marketing, customer support, or revenue-critical sites.
Technical view
The issue is CWE-862 missing authorization in wpfm_delete_multiple_files(). The vulnerable function lacks a required capability check, allowing network-accessible unauthenticated post deletion. CVSS 3.1 is 7.5, with low attack complexity, no privileges, no user interaction, and high integrity impact.
Likely exposure
Exposure is limited to WordPress installations using nmedia Frontend File Manager Plugin versions up to and including 21.5. The supplied sources do not identify vulnerable hosting platforms beyond WordPress sites with this plugin active.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. However, the vulnerability is remotely reachable, unauthenticated, and low complexity, so public-facing affected WordPress sites should be treated as urgent.
Researcher notes
Evidence supports missing authorization and arbitrary post deletion through wpfm_delete_multiple_files() in versions through 21.5. The supplied bundle does not prove active exploitation, name a specific fixed version, or describe confidentiality impact.
Mitigation direction
- Identify all WordPress sites running Frontend File Manager Plugin.
- Confirm whether installed plugin versions are up to and including 21.5.
- Check Wordfence and vendor guidance for the fixed release before upgrading.
- Disable the plugin temporarily if no confirmed fixed release is deployable.
- Verify recent backups can restore deleted posts and pages.
Validation and detection
- Inventory plugin installation and version across WordPress environments.
- Review whether wpfm_delete_multiple_files() includes a capability check.
- Inspect logs for unauthenticated requests tied to unexpected post deletion.
- Compare recent content changes against editorial activity and backups.
- Confirm remediation by verifying the vulnerable version is no longer present.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
