CVE-2026-82003 is an improper input validation vulnerability (CWE-20) in Adobe Campaign Classic that could lead to arbitrary code execution in the context of the current user. A low-privileged attacker can exploit this vulnerability without user interaction, although exploitation depends on external conditions beyond the attacker's control. The vulnerability changes the security scope and impacts confidentiality, integrity, and availability with high severity.

Successful exploitation allows an attacker with low privileges to execute arbitrary code as the current user, potentially compromising system confidentiality, integrity, and availability. The vulnerability does not require user interaction but depends on conditions outside the attacker's control. There are no known exploits in the wild at this time.
