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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on 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

Since no official patches are currently available, European organizations should implement compensating controls immediately. These include restricting network access to the ALGO 8180 web interface using firewalls or VPNs to limit exposure to trusted administrators only. Employ web application firewalls (WAFs) capable of detecting and blocking XSS payloads targeting the syslog functionality. Regularly monitor device logs and network traffic for unusual activity indicative of exploitation attempts. Disable or restrict access to the syslog viewing feature if feasible until a patch is released. Educate administrators on the risks of XSS and encourage the use of strong, unique credentials for device management interfaces. Once a vendor patch is released, prioritize prompt deployment. Additionally, consider network segmentation to isolate these devices from critical infrastructure to limit potential lateral movement. Conduct periodic security assessments of the devices and their configurations to ensure no additional vulnerabilities are present.

Description

CVE-2026-0788 is a persistent cross-site scripting (XSS) vulnerability in the ALGO 8180 IP Audio Alerter's web interface, specifically in the syslog viewing functionality. This flaw allows unauthenticated remote attackers to inject arbitrary scripts, which execute with the privileges of the targeted user. Exploitation does not require authentication or user interaction, increasing its risk. The vulnerability stems from improper input validation, enabling attackers to manipulate the web UI and potentially perform unauthorized actions. Although the CVSS score is medium (5.3), the lack of authentication requirement raises concerns about ease of exploitation. No known exploits are currently reported in the wild. European organizations using ALGO 8180 devices should prioritize patching or mitigating this issue to prevent potential compromise of administrative sessions or further attacks leveraging the injected scripts.

Impact

For European organizations, the exploitation of this vulnerability could lead to unauthorized control or manipulation of ALGO 8180 IP Audio Alerter devices, which are often deployed in security-sensitive environments such as public safety, transportation hubs, and corporate facilities. Attackers could leverage the XSS flaw to hijack administrative sessions, inject malicious commands, or pivot to other network segments. This could disrupt alerting systems, degrade operational security, or facilitate further attacks such as phishing or malware deployment. Given that the vulnerability requires no authentication, attackers can target exposed devices directly over the network, increasing the attack surface. The integrity of alerting messages and system logs could be compromised, potentially leading to delayed or missed alerts. Although availability impact is not indicated, the indirect effects on operational security and trustworthiness of alerting systems could be substantial. Organizations relying on these devices for critical communications should consider this vulnerability a significant risk to their security posture.

Summary

CVE-2026-0788 is a persistent cross-site scripting vulnerability identified in the ALGO 8180 IP Audio Alerter, a device used for IP-based audio alerting. The vulnerability resides in the web user interface's syslog viewing functionality, where user-supplied data is not properly sanitized or validated before being rendered. This improper neutralization of input (CWE-79) allows an attacker to inject malicious JavaScript code that persists within the application context. Because the vulnerability can be exploited without authentication or user interaction, an attacker can remotely send crafted requests to the device, causing the malicious script to execute in the context of any user accessing the syslog page. This can lead to unauthorized actions such as session hijacking, unauthorized commands, or manipulation of the device's web interface. The CVSS 3.0 base score is 5.3, indicating a medium severity primarily due to the lack of confidentiality impact but with integrity implications. The vulnerability was reported by the Zero Day Initiative (ZDI) under identifier ZDI-CAN-28298 and affects version 5.5 of the product. No patches or exploit code are currently publicly available, but the risk remains significant given the device's role in critical alerting infrastructure.
