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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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 2026-10-26.

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 immediately review and restrict the assignment of Editor roles within groov View Server to only trusted personnel. Implement strict network segmentation to limit access to the groov View API endpoints, ensuring that only authorized systems and users can reach the users endpoint. Monitor API access logs for unusual or unauthorized requests to the users endpoint, focusing on Editor role accounts. Employ multi-factor authentication (MFA) where possible to reduce the risk of credential compromise. Since no official patches are currently available, consider deploying compensating controls such as API gateway filtering or web application firewalls (WAF) to block or monitor access to the vulnerable endpoint. Engage with Opto 22 for timely patch releases and apply updates promptly once available. Conduct regular security audits and penetration tests focusing on role-based access controls and API security. Educate users with Editor privileges about the sensitivity of their access and enforce strong password policies to reduce the risk of credential theft.

Description

CVE-2025-13084 is a high-severity vulnerability in Opto 22's groov View Server R1.0a where the users endpoint in the API exposes all users' metadata including API keys to any user with Editor role privileges. This exposure includes Administrator API keys, potentially allowing privilege escalation or unauthorized access to critical system functions. The vulnerability requires network access and Editor-level privileges but no user interaction, and it impacts confidentiality and availability. No known exploits are currently reported in the wild. European organizations using groov View Server in industrial control or automation environments are at risk, especially those with Editor role users who might be targeted or compromised. Mitigation requires restricting Editor role assignments, monitoring API access logs, and applying vendor patches once available. Countries with significant industrial automation sectors and Opto 22 deployments, such as Germany, France, Italy, and the UK, are most likely to be affected. The CVSS score of 7.6 reflects the high confidentiality impact and ease of exploitation with low attack complexity.

Impact

For European organizations, particularly those in industrial automation, manufacturing, and critical infrastructure sectors using Opto 22 groov View Server, this vulnerability poses a significant risk. Exposure of API keys can lead to unauthorized access to control systems, enabling attackers to manipulate operational processes, disrupt services, or exfiltrate sensitive operational data. The confidentiality breach could facilitate further lateral movement within networks, potentially impacting integrity and availability of industrial processes. Given the reliance on automation in sectors such as energy, manufacturing, and transportation across Europe, exploitation could lead to operational downtime, safety hazards, and financial losses. The requirement for Editor-level privileges somewhat limits the attack surface but does not eliminate risk, especially if Editor roles are widely assigned or if credentials are compromised through other means. The lack of user interaction needed for exploitation increases the threat level, as attacks can be automated or executed remotely once access is obtained.

CWE-1230Exposure of Sensitive Information Through Metadata (opens in a new tab)
Base weakness
The product prevents direct access to a resource containing sensitive information, but it does not sufficiently limit access to metadata that is derived from the original, sensitive information.
