Confidentiality: Low
Integrity: None
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: 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 23 Oct 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.

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.

What to do

AI-suggested

1. Immediate mitigation involves restricting access to the cohort search web service to only trusted and necessary users, minimizing the number of accounts with any level of permission in the affected contexts. 2. Implement strict role-based access control (RBAC) policies and validate that access checks are enforced correctly at all context levels within the web service. 3. Monitor and audit access logs for unusual or unauthorized attempts to query cohort information, focusing on users with lower-level permissions. 4. If available, apply vendor patches or updates addressing this vulnerability as soon as they are released. 5. Employ network segmentation and firewall rules to limit exposure of the vulnerable service to only essential internal or external networks. 6. Conduct a thorough review of the web service's access control mechanisms and perform penetration testing to identify and remediate similar access control weaknesses. 7. Educate administrators and users about the risk of privilege escalation and enforce strong authentication and account management practices to reduce the risk of compromised lower-privilege accounts.

Description

A flaw in the cohort search web service allowed users with permissions in lower contexts to access cohort information from the system context, revealing restricted administrative data.

Impact

The primary impact of CVE-2025-62395 is unauthorized disclosure of sensitive administrative cohort data, which could lead to information leakage and potential reconnaissance by attackers. While the vulnerability does not affect data integrity or system availability, the exposure of restricted administrative information can aid attackers in planning further attacks or gaining deeper system insights. Organizations relying on the affected software versions may face compliance and privacy risks if sensitive data is accessed by unauthorized users. The requirement of lower-level privileges to exploit the vulnerability means that insider threats or compromised accounts with limited access could escalate their visibility into sensitive data. Although no active exploitation is currently known, the vulnerability could be targeted in the future, especially in environments where cohort data is critical to operations or contains personally identifiable information (PII). The medium CVSS score reflects moderate risk, but the impact could be significant depending on the sensitivity of the exposed data and the organization's security posture.
