The vulnerability CVE-2026-32403 in Toocheke Companion arises from improper neutralization of input during web page generation, leading to DOM-based Cross-site Scripting (XSS). This allows an attacker to inject malicious scripts that execute in the context of the victim's browser. The affected versions include all releases up to 1.194. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, required privileges, user interaction, and impacts on confidentiality, integrity, and availability. No vendor advisory or patch information is available at this time.

Successful exploitation can lead to partial compromise of confidentiality, integrity, and availability of the affected system due to DOM-based XSS. This may allow attackers to execute arbitrary scripts in the context of the victim user, potentially leading to session hijacking or other client-side impacts. However, exploitation requires user interaction and low privileges.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with untrusted input and consider applying any available workarounds or input validation controls if feasible.
