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.
Casky was already ahead
This CVE exploits attack patterns that Casky's 284matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
The Contact Form to Any API WordPress plugin before version 3.0.7 contains an information disclosure vulnerability (CWE-200) that exposes uploaded files through predictable naming schemes. When users submit files via contact forms, the plugin stores them in publicly accessible directories using non-random filenames, allowing unauthenticated attackers to enumerate and download files submitted by other users. This affects any WordPress site running the vulnerable plugin version, particularly those collecting sensitive documents, personally identifiable information, or confidential business data through contact forms. The vulnerability is especially dangerous because it requires no authentication and no complex exploitation—attackers simply need to guess or iterate through predictable filenames to access others' submissions.
Casky's 284 matched skills leverage Claude AI's extended reasoning to detect the attack patterns associated with MITRE techniques TA0043 (Reconnaissance) and TA0009 (Collection). Practitioners using Casky would identify reconnaissance activity through detection of unusual file enumeration requests targeting contact form directories with sequential or patterned filename attempts. The Collection technique indicators would surface when access logs show systematic downloads of files with predictable naming conventions—for example, multiple requests for incrementally named files or rapid directory traversal attempts. By mapping these behavioral patterns to the underlying weakness (improper randomization in file handling), Casky helps practitioners spot the reconnaissance phase before data exfiltration occurs, enabling them to audit existing exposure, patch vulnerable plugin versions, and implement access controls on upload directories before attackers systematically harvest submitted files.
