DescriptionCVE.org

The Contact Form to Any API WordPress plugin before 3.0.7 does not use a random filename when copying files uploaded through contact forms into a publicly accessible directory, allowing unauthenticated attackers to enumerate and download files submitted by other users.

AnalysisAI

File enumeration and unauthorized download is possible in the Contact Form to Any API WordPress plugin (all versions before 3.0.7) because uploaded contact form attachments are stored in a publicly accessible directory using predictable, non-random filenames. Unauthenticated remote attackers can discover the upload path by submitting a form themselves, then systematically enumerate filenames to retrieve files - potentially containing PII, identity documents, or sensitive business attachments - submitted by other users. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Submit file via public contact form

Impact
Exfiltrate sensitive contact form attachments

Vulnerability AssessmentAI

Exploitation Exploitation requires that the Contact Form to Any API plugin be installed and active on a WordPress site running a version prior to 3.0.7, and that at least one contact form on the site accepts file attachments. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) correctly reflects the unauthenticated, low-complexity, network-accessible nature of this vulnerability with high confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker submits a benign file through the public contact form on a target WordPress site, observing the returned or stored URL to identify the upload directory path and filename pattern. They then iterate over predictable filename variants - sequential integers, timestamps, or other enumerable schemes - issuing direct HTTP GET requests to retrieve files uploaded by prior legitimate users. …
Remediation Update the Contact Form to Any API plugin to version 3.0.7 or later, which resolves the issue by introducing randomized filenames for uploaded attachments. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all WordPress instances using Contact Form to Any API and their current versions; prioritize patches for any deployment handling regulated data (PII, PHI, or payment information). …
