Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Given the absence of an official patch at this time, European organizations should implement compensating controls to mitigate risk. These include restricting network access to the ALGO 8180 IP Audio Alerter web interface via firewall rules or network segmentation, ensuring the device is not exposed to untrusted networks or the internet. Employing strong network-level authentication and VPNs for remote access can reduce unauthorized exposure. Monitoring network traffic for unusual requests to the device's web interface may help detect exploitation attempts. Organizations should also engage with ALGO for timely updates or patches and plan for prompt deployment once available. Additionally, reviewing and hardening device configurations to minimize sensitive data exposure and disabling unnecessary web UI features can reduce attack vectors. Regular security assessments and penetration testing focused on these devices can identify residual risks.

Description

CVE-2026-0789 is a medium severity vulnerability affecting ALGO 8180 IP Audio Alerter devices, specifically version 5.5. It involves the exposure of sensitive authentication cookie information within the web UI response body, allowing remote attackers to access sensitive data without authentication or user interaction. The flaw stems from improper handling of sensitive information in the device's web interface. While it does not allow direct control or disruption of the device, the disclosed information could facilitate further attacks. No known exploits are currently reported in the wild. European organizations using these devices should be aware of this information disclosure risk and apply mitigations promptly.

Impact

For European organizations deploying ALGO 8180 IP Audio Alerter devices, this vulnerability poses a risk of unauthorized disclosure of sensitive authentication information. While it does not directly allow device control or denial of service, the exposure of authentication cookies can facilitate lateral movement, unauthorized access, or reconnaissance within the network. Organizations relying on these devices for critical audio alerting, such as in public safety, transportation hubs, or corporate environments, could face increased risk of targeted attacks if attackers leverage this information to escalate privileges or compromise device integrity indirectly. The lack of authentication requirement increases the attack surface, especially for devices accessible from less protected network segments. This could lead to breaches of confidentiality and potential compliance issues under European data protection regulations if sensitive information is exposed or misused.

Summary

CVE-2026-0789 is a vulnerability categorized under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) found in the ALGO 8180 IP Audio Alerter, specifically version 5.5. The vulnerability arises from the device's web-based user interface improperly including an authentication cookie within the HTTP response body. This flaw allows remote attackers to retrieve sensitive authentication tokens without requiring any authentication or user interaction, thereby exposing sensitive information that should remain confidential. The vulnerability is network exploitable (AV:N), requires low attack complexity (AC:L), and no privileges or user interaction (PR:N/UI:N) are needed, making it relatively easy to exploit. However, the impact is limited to confidentiality (C:L) without affecting integrity or availability. The vulnerability was identified and assigned by the Zero Day Initiative (ZDI) as ZDI-CAN-28297 and published on January 23, 2026. No patches or known exploits are currently available, but the exposure of authentication cookies could enable attackers to impersonate legitimate users or gain further access to device functions if combined with other vulnerabilities or misconfigurations.

Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
