This vulnerability (CVE-2026-39434) affects WebAppick CTX Feed versions up to 6.6.26 and is classified as CWE-502: Deserialization of Untrusted Data. It involves PHP Object Injection, which can be exploited by a user with shop manager privileges to execute malicious code or manipulate application behavior. The CVSS 3.1 base score is 7.2, indicating a high severity with network attack vector, low attack complexity, required privileges at the high level, no user interaction, and impacts to confidentiality, integrity, and availability. There is no vendor advisory or patch available at this time, and no known exploits in the wild have been reported.

Successful exploitation could allow an attacker with shop manager privileges to execute arbitrary code or manipulate application data, leading to full compromise of confidentiality, integrity, and availability of the affected system. This could result in unauthorized access, data modification, or denial of service within the CTX Feed environment.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict shop manager privileges to trusted users only and monitor for suspicious activity related to deserialization processes. Avoid importing untrusted data that could trigger PHP Object Injection.
