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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 19 Nov 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
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 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

1. Apply vendor patches immediately once they become available to address the authorization bypass vulnerability. 2. Until patches are released, restrict access to the AtHoc Management Console to a minimal set of trusted administrators using network segmentation and strong access controls. 3. Implement strict role-based access controls (RBAC) and audit logging to detect and prevent unauthorized access attempts. 4. Monitor network traffic and management console logs for unusual or unauthorized access patterns that may indicate exploitation attempts. 5. Conduct regular security assessments and penetration testing focused on multi-tenant access controls within the AtHoc environment. 6. Educate administrators on the risks of IDOR vulnerabilities and the importance of validating user inputs and keys. 7. Consider isolating organizational instances or deploying separate AtHoc environments for different organizations if feasible to reduce cross-tenant exposure.

Description

An Insecure Direct Object Reference (IDOR) vulnerability in the Management Console of BlackBerry® AtHoc® (OnPrem) version 7.21 could allow an attacker to potentially gain unauthorized knowledge about other organizations hosted on the same Interactive Warning System (IWS).

Impact

For European organizations, the primary impact is unauthorized disclosure of sensitive organizational information hosted on the same BlackBerry AtHoc IWS platform. This exposure could aid threat actors in reconnaissance, enabling more targeted attacks or social engineering campaigns. While the vulnerability does not allow data modification or service disruption, the leakage of confidential information could undermine trust and operational security, especially in sectors such as government, emergency services, and critical infrastructure. Given AtHoc's role in crisis communication, any compromise of confidentiality could have downstream effects on emergency preparedness and response coordination. Organizations relying on AtHoc OnPrem 7.21 should consider the risk of information leakage as a significant concern, particularly where multiple organizations share the same platform instance.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #24OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Architecture and Design · Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
