CVE-2026-112103: A vulnerability has been found in f3-factory fatfree-core up to 3.9.2. This vulnerability affects the function _curl of the file web.php of the component HTTP Client. Such manipulation leads to improper certificate validation. The attack may be performed from remote. Attacks of this nature are highly complex. It is stated that the exploitability is difficult. Upgrading to version 3.9.3 is able to resolve this issue. The name of the patch is a2c755c8dc9ad0eb7d5fd261b09aff90f649433c. You should upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
The exploitability of CVE-2026-112103 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2026-112103 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-112103, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
