LowCVSS 3.7
Published: Updated: Translated: NVD NIST

Summary

A vulnerability was found in f3-factory fatfree-core up to 3.9.2 in the _curl function of web.php within the HTTP client component. Manipulation leads to improper certificate validation, and the attack may be performed remotely, though it is highly complex and difficult to exploit. Upgrading to version 3.9.3 resolves the issue (patch a2c755c8dc9ad0eb7d5fd261b09aff90f649433c).

Risk Assessment

Improper certificate validation may allow an attacker to intercept or impersonate a TLS connection, leading to data leakage or actions on behalf of the user. Due to the high attack complexity, the risk is limited but still relevant.

Recommendation

Upgrade fatfree-core to version 3.9.3 or later. Until then, avoid processing sensitive data through the application.
