AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H
Nonce is publicly exposed so PR:N is justified; unauthenticated remote deletion with no UI gives AC:L, and file deletion impacts integrity and availability but not confidentiality.

The RapiSafe - Secure Multi File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the handleAjaxRemoveUpload function in all versions up to, and including, 1.0.4. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The nonce required to invoke the removal handler is exposed in public-facing JavaScript as RSMFCF7Vars.nonce on every Contact Form 7 page rendering a RapiSafe upload field, making it obtainable by any unauthenticated visitor.

AnalysisAI
Arbitrary file deletion in the RapiSafe - Secure Multi File Upload for Contact Form 7 WordPress plugin (versions through 1.0.4) lets unauthenticated attackers delete any file the web server can write to, and deleting wp-config.php can pivot to remote code execution by forcing WordPress into its installer flow. The flaw stems from missing path validation in the handleAjaxRemoveUpload AJAX handler, and the CSRF nonce that gates the handler is leaked to any anonymous visitor as RSMFCF7Vars.nonce in the page's public JavaScript, neutralizing the only access control. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target site (a) runs the RapiSafe plugin at version 1.0.4 or earlier alongside Contact Form 7, and (b) has at least one public CF7 form that renders a RapiSafe upload field - that rendering is what emits the RSMFCF7Vars.nonce value and exposes the handleAjaxRemoveUpload handler to anonymous users. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H) describes a remote, low-complexity, unauthenticated attack requiring no user interaction, with high integrity and availability impact and no confidentiality impact - consistent with unauthenticated arbitrary file deletion rather than data theft, and the description's nonce-exposure detail credibly supports the PR:N (unauthenticated) rating rather than contradicting it. … 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 | No vendor-released patched version is identified in the available data - the description states all versions through 1.0.4 are affected and no fixed release is cited - so do not assume a fix exists; check the vendor/Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/49f67bbb-cbd0-40ae-ae00-9cb72b041e22?source=cve) for an update beyond 1.0.4 and apply it as the primary remediation if published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: immediately uninstall RapiSafe plugin (all versions ≤1.0.4) from all WordPress instances and review web server and application logs for AJAX POST requests to the handleAjaxRemoveUpload endpoint to detect attempted exploitation. …
