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: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

CVE published 25 Nov 2025
Detectable: no evidence on record.

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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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.

AI-suggested

To mitigate CVE-2025-64062, organizations should implement strict server-side validation to ensure that the email parameter in the /api/V2/pp_users endpoint matches the authenticated user's session identity. The application logic must reject any requests where the email parameter does not correspond to the session or is missing. Specifically, the system should never default to the first user or any privileged account when the email parameter is blank or invalid. Access control checks must be enforced at the API level to prevent unauthorized data access and privilege escalation. Organizations should audit their current deployments of Primakon Pi Portal to identify affected versions and restrict access to the vulnerable API endpoint through network segmentation or firewall rules until a patch is available. Monitoring and logging of API requests for unusual email parameter values or access patterns can help detect exploitation attempts. Where possible, multi-factor authentication should be enforced for administrative accounts to reduce the risk of compromise. Finally, organizations should engage with the vendor or community to obtain patches or updates addressing this vulnerability and apply them promptly once available.

Description

The Primakon Pi Portal 1.0.18 /api/V2/pp_users?email endpoint is used for user data filtering but lacks proper server-side validation against the authenticated session. By manipulating the email parameter to an arbitrary value (e.g., otheruser@user.com), an attacker can assume the session and gain full access to the target user's data and privileges. Also, if the email parameter is left blank, the application defaults to the first user in the list, who is typically the application administrator, resulting in an immediate Privilege Escalation to the highest level.

Impact

For European organizations, the impact of CVE-2025-64062 is substantial. Unauthorized access to user accounts can lead to data breaches involving personal, financial, or operational information, violating GDPR and other data protection regulations. The ability to escalate privileges to an administrator level without proper authentication can result in full system compromise, including unauthorized configuration changes, data manipulation, and potential disruption of services. This can affect business continuity, damage reputation, and incur regulatory penalties. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that rely on Primakon Pi Portal for user management or administrative tasks are particularly vulnerable. The lack of user interaction and low complexity of exploitation increase the likelihood of successful attacks, potentially enabling lateral movement within networks. Additionally, the default fallback to the administrator account when the email parameter is blank presents a severe risk of immediate full system takeover. This vulnerability could be leveraged in targeted attacks or automated scanning campaigns, increasing exposure for European entities using this software.

Class weaknessLikelihood of exploit: HighOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that you perform access control checks related to your business logic. These checks may be different than the access control checks that you apply to more generic resources such as files, connections, processes, memory, and database records.
