CVE-2026-44265
Description
A flaw was found in Elo. This vulnerability allows an attacker to achieve arbitrary code execution or Structured Query Language (SQL) injection by supplying malicious input to the programmatic Abstract Syntax Tree (AST) interface. Because the interface inserts unvalidated input directly into generated code, crafted values are executed as commands or queries across target runtime environments.
Statement
Red Hat has rated this vulnerability as Important because full compromise of host execution environments or underlying databases can occur if an application ingests untrusted structures into the compilation pipeline. Exploitation requires non-default integration patterns where external data directly shapes internal syntax tree nodes rather than standard parsed language expressions, which limits the attack surface. As a result, the risk is elevated primarily for custom implementations that bridge raw serialized data into backend source generation.
Understanding the Weakness (CWE)
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.
