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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 19 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 31 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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.

What to do

Upgrade Ubiquiti UniFi Network Application to 10.2.97, 10.1.89 or 9.0.118.

AI-suggested

Organizations should immediately review and restrict authenticated access to the UniFi Network Application, enforcing the principle of least privilege and strong authentication mechanisms such as multi-factor authentication. Network segmentation should be employed to limit access to the management interface only to trusted administrators and secure management networks. Monitoring and logging of all privileged actions within the application should be enhanced to detect suspicious activities indicative of exploitation attempts. If you cannot patch yet, consider implementing Web Application Firewall (WAF) rules to detect and block NoSQL injection patterns targeting the application. Regularly audit user accounts and remove or disable unnecessary or dormant accounts to reduce the attack surface. Educate administrators about the risks of NoSQL injection and the importance of secure coding and input validation practices. Finally, maintain up-to-date backups of network configurations to enable recovery in case of compromise.

Description

An Authenticated NoSQL Injection vulnerability found in UniFi Network Application could allow a malicious actor with authenticated access to the network to escalate privileges.

Impact

The primary impact of CVE-2026-22558 is unauthorized privilege escalation within the UniFi Network Application, which can lead to exposure of sensitive network configuration data and potentially allow attackers to manipulate network management functions. This compromises the confidentiality of network operations and could facilitate further attacks such as lateral movement or persistent access. Since the vulnerability requires authenticated access, the risk is heightened in environments where user credentials are weak, reused, or compromised. The change in scope means that the attacker could affect components beyond their initial access level, increasing the potential damage. Organizations relying on UniFi Network Application for network management, including enterprises, service providers, and managed security service providers, face increased risk of network compromise and data breaches. The absence of known exploits in the wild currently limits immediate widespread impact, but the vulnerability remains a significant threat if exploited. Additionally, the vulnerability could undermine trust in network infrastructure and lead to operational disruptions if attackers manipulate network configurations.
