Confidentiality: High
Integrity: High
Availability: None

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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 21 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 2026-10-25.

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 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

European organizations should prioritize updating all affected UniFi Connect Display Cast devices to the patched versions: 1.10.7 or later for standard, 1.0.94 or later for Pro, and 1.1.8 or later for Lite editions. Beyond patching, organizations should enforce strict access controls on the API, including network segmentation to limit API access only to trusted management hosts. Implement strong authentication mechanisms, such as multi-factor authentication, to reduce risk from compromised credentials. Regularly audit API access logs for suspicious activities and unauthorized changes. Employ network monitoring to detect anomalous traffic patterns targeting these devices. Where possible, disable or restrict API access if not required. Additionally, maintain an inventory of all UniFi Connect Display Cast devices to ensure comprehensive coverage of patches and controls. Educate administrators on the risks of improper access control and the importance of credential security. Finally, integrate these devices into broader vulnerability management and incident response processes to ensure rapid detection and remediation of any exploitation attempts.

Description

An Improper Access Control could allow a malicious actor authenticated in the API of certain UniFi Connect Display Cast devices to make unsupported changes to the system. Affected Products: UniFi Connect Display Cast (Version 1.10.3 and earlier) UniFi Connect Display Cast Pro (Version 1.0.89 and earlier) UniFi Connect Display Cast Lite (Version 1.0.3 and earlier) Mitigation: Update UniFi Connect Display Cast to Version 1.10.7 or later Update UniFi Connect Display Cast Pro to Version 1.0.94 or later Update UniFi Connect Display Cast Lite to Version 1.1.8 or later

Impact

For European organizations, this vulnerability poses a significant risk especially for those deploying UniFi Connect Display Cast devices in enterprise, educational, or public sector environments. Unauthorized changes to device configurations could lead to exposure of sensitive network information, interception or manipulation of data streams, or creation of backdoors for further attacks. Since these devices are often integrated into network infrastructure for display and communication purposes, compromise could affect operational integrity and confidentiality. The requirement for authentication means insider threats or compromised credentials could be leveraged by attackers. The impact is heightened in sectors with strict data protection regulations such as GDPR, where unauthorized data access or leakage could result in legal and financial penalties. Additionally, disruption or manipulation of these devices could impair business continuity or public services relying on them. The absence of known exploits in the wild currently provides a window for mitigation, but the high severity score and ease of exploitation suggest that threat actors may develop exploits soon.

Pillar weaknessCWE Top 25 (2025): #19OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design · Separation of Privilege
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.
