CVE-2026-3137 is a stack-based buffer overflow vulnerability identified in version 1.0 of the CodeAstro Food Ordering System, specifically within an unspecified function of the executable file food_ordering.exe. The vulnerability arises when an attacker with local access manipulates input or data in a way that causes the program to write more data to a buffer on the stack than it can hold, leading to memory corruption. This type of overflow can potentially allow an attacker to overwrite the return address or other control data on the stack, possibly enabling arbitrary code execution or crashing the application. However, exploitation requires local access with low privileges, no user interaction is needed, and the attack complexity is low. The CVSS 4.8 score reflects these factors, indicating a medium severity level with limited impact on confidentiality, integrity, and availability. The vulnerability does not require network access, limiting its scope to local environments. No known public exploits are currently reported, and no patches have been published by the vendor yet. The vulnerability's presence in a food ordering system executable suggests that it could disrupt local operations or be leveraged for privilege escalation if combined with other vulnerabilities. Organizations using this software should be aware of the risk and implement controls to limit local access and monitor for anomalous behavior until a patch is available.

The primary impact of CVE-2026-3137 is the potential for local attackers to cause a stack-based buffer overflow in the CodeAstro Food Ordering System, which could lead to application crashes or potentially arbitrary code execution. Although the vulnerability requires local access and low privileges, successful exploitation could allow an attacker to disrupt food ordering operations, leading to denial of service or manipulation of order data. This could affect business continuity and customer trust, especially in environments relying heavily on this software for daily operations. The limited attack vector reduces the risk of widespread remote exploitation, but insider threats or compromised local accounts could leverage this vulnerability. The absence of known exploits in the wild and the medium CVSS score suggest a moderate risk level. However, if combined with other vulnerabilities or misconfigurations, the impact could escalate. Organizations with multiple local users or shared workstations running this software are at higher risk. The vulnerability could also be a stepping stone for privilege escalation or lateral movement within a network if attackers gain local foothold.

To mitigate CVE-2026-3137, organizations should immediately restrict local access to systems running CodeAstro Food Ordering System 1.0, ensuring only trusted and authorized personnel can interact with the software. Implement strict user account controls and monitor local user activities for unusual behavior indicative of exploitation attempts. Employ application whitelisting and endpoint protection solutions that can detect anomalous memory corruption or buffer overflow attempts. Since no patches are currently available, consider isolating affected systems from critical networks to limit potential lateral movement. Conduct regular backups of critical data to enable recovery in case of disruption. Engage with the vendor for updates and apply patches promptly once released. Additionally, perform code audits or penetration testing focused on local privilege escalation vectors to identify and remediate related weaknesses. Educate staff about the risks of local exploitation and enforce the principle of least privilege to minimize attack surface.
