CVE-2026-78136

Description

A flaw was found in CHIRP from chirpmyradio. A local attacker can achieve arbitrary code execution by tricking a user into processing a specially crafted Comma Separated Values (CSV) file. This vulnerability, an eval injection, occurs within the _clean_tmode function when handling CSV data, leading to high impacts on confidentiality, integrity, and availability.

Statement

Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.

Mitigation

To mitigate this vulnerability, users should avoid importing or processing CSV files from untrusted sources with CHIRP. Exercise caution when handling CSV data, especially if its origin is unknown or suspicious.

Understanding the Weakness (CWE)

CWE-94

Access Control

Technical Impact: Bypass Protection Mechanism

In some cases, injectable code controls authentication; this may lead to a remote vulnerability.

Access Control

Technical Impact: Gain Privileges or Assume Identity

Injected code can access resources that the attacker is directly prevented from accessing.

Integrity,Confidentiality,Availability

Technical Impact: Execute Unauthorized Code or Commands

When a product allows a user's input to contain code syntax, it might be possible for an attacker to craft the code in such a way that it will alter the intended control flow of the product. As a result, code injection can often result in the execution of arbitrary code. Code injection attacks can also lead to loss of data integrity in nearly all cases, since the control-plane data injected is always incidental to data recall or writing.

Non-Repudiation

Technical Impact: Hide Activities

Often the actions performed by injected control code are unlogged.
