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: 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 27 Feb 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

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 29 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

AI-suggested

To mitigate CVE-2026-28424, organizations should upgrade Statamic CMS to versions 5.73.11 or later, or 6.4.0 or later, where the authorization checks have been properly implemented. If immediate upgrading is not feasible, administrators should restrict access to the control panel and its endpoints to trusted users only, minimizing the number of users with any access privileges. Implement network-level controls such as IP whitelisting or VPN access to limit exposure of the CMS interface. Review and tighten user permissions to ensure that only necessary users have access to sensitive endpoints. Monitor logs for unusual access patterns to the user fieldtype’s data endpoint that might indicate exploitation attempts. Additionally, consider implementing web application firewalls (WAFs) with custom rules to detect and block unauthorized requests targeting this endpoint. Educate users about phishing risks, as leaked email addresses could be used in social engineering attacks. Regularly audit CMS configurations and user permissions to prevent privilege creep. Finally, maintain an incident response plan to quickly address any suspected data exposure.

Description

Statmatic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.11 and 6.4.0, user email addresses were included in responses from the user fieldtype’s data endpoint for control panel users who did not have the "view users" permission. This has been fixed in 5.73.11 and 6.4.0.

Impact

The primary impact of CVE-2026-28424 is the unauthorized disclosure of email addresses of control panel users within Statamic CMS installations. This leakage can facilitate targeted phishing attacks, social engineering, and further reconnaissance by threat actors. Organizations relying on Statamic CMS for website or content management may inadvertently expose sensitive user information to unauthorized internal or external actors with low-level access. While the vulnerability does not allow direct system compromise or data manipulation, the exposure of email addresses can lead to secondary attacks that compromise organizational security posture. The impact is particularly significant for organizations with high-value or sensitive user accounts, such as government agencies, financial institutions, or enterprises with critical internal communications. Additionally, the vulnerability could erode user trust and violate privacy regulations if exploited. Since exploitation requires only low privileges and no user interaction, attackers who gain minimal access to the CMS could leverage this flaw to escalate their reconnaissance efforts. However, the absence of known exploits in the wild reduces immediate risk, though the vulnerability should be treated seriously given its potential for abuse.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
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 access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
