Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.
Prevents unauthorized exposure of sensitive information by prohibiting untrusted external systems from processing or storing it.
By enforcing authorization matching prior to sharing, the control reduces the risk of exposing sensitive information to unauthorized actors.
Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.
Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.
Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.
Retaining and monitoring training records confirms personnel have completed privacy and security awareness training on handling sensitive data, reducing the chance of unauthorized exposure due to lack of knowledge.

Deeper analysisAI
CVE-2026-0789 is an information disclosure vulnerability in the web-based user interface of ALGO 8180 IP Audio Alerter devices, stemming from the inclusion of an authentication cookie in the response body. This flaw, classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), arises from inadequate management of sensitive data and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Published on January 23, 2026, it affects affected installations of these devices without requiring authentication for exploitation.
Remote attackers can exploit this vulnerability over the network with low complexity and no privileges, user interaction, or special access. By sending crafted requests to the web UI, they can retrieve the authentication cookie and other sensitive information disclosed in the response, enabling potential further compromise within the device's context, such as session hijacking or deeper reconnaissance.
The Zero Day Initiative advisory at https://www.zerodayinitiative.com/advisories/ZDI-26-011/ details the vulnerability, originally canonized as ZDI-CAN-28297. Security practitioners should review this advisory for specific mitigation steps, as no patch details are provided in the initial disclosure.
