Summary

CVE-2026-19780 is a high-severity Eval Injection (CWE-95) vulnerability in Zerodayinitiative (inferred from references). Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 47th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Vulnerability Data

Koha Eval Code Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Koha. Authentication is required to exploit this vulnerability. The specific flaw exists within the web service, which listens on…

more

TCP port 8081 by default. The issue results from the lack of proper validation of a user-supplied string before passing it to the eval function. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-29165.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and code analysis can discover eval-injection flaws but does not stop their introduction.

Secure-development standards and tools can mandate safe coding patterns that avoid unsafe dynamic evaluation.

Input validation explicitly requires neutralizing untrusted data before it reaches dynamic evaluation constructs such as eval.
