Summary

CVE-2026-3137 is a medium-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Codeastro Food Ordering System. Its CVSS base score is 4.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 6.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).

Deeper analysis

CVE-2026-3137 is a stack-based buffer overflow vulnerability affecting CodeAstro Food Ordering System 1.0, specifically an unknown function within the food_ordering.exe file. The issue, linked to CWEs-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), CWE-121 (Stack-based Buffer Overflow), and CWE-787 (Out-of-bounds Write), was published on 2026-02-25 and carries a CVSS v3.1 base score of 5.3 (AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L), rating it as medium severity.

The vulnerability can only be exploited from a local environment by an attacker with low privileges, requiring low attack complexity and no user interaction. Successful exploitation could result in limited impacts, including partial disclosure of sensitive information, limited modification of data, and limited denial of service through partial availability disruption.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Local stack-based buffer overflow (CWE-121/119/787) in a client executable allows low-privileged local attackers to corrupt memory and achieve code execution or limited privilege escalation on the host.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces memory protections (e.g., ASLR, DEP, stack canaries) that block exploitation of the stack-based buffer overflow in food_ordering.exe.

prevent

Requires bounds checking and input validation on all untrusted data entering the application, preventing the out-of-bounds write that triggers CVE-2026-3137.

prevent

Restricts local users to the minimum privileges needed, limiting the impact and attack surface even if the buffer overflow is reached.
