CVE-2026-76802

Description

A flaw was found in Nuclei, a vulnerability scanner. The Dynamic Application Security Testing (DAST) template loading process fails to enforce signature checks for code templates. This allows an attacker to craft a malicious template containing unsigned code, which, when processed by an operator enabling DAST, can lead to the execution of arbitrary shell commands.

Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities

Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
