Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 Mar 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
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 30 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.

AI-suggested

To mitigate CVE-2026-3110, organizations should immediately implement strict access control checks on the '/administracion/admin_usuarios.cgi' endpoint, ensuring that only authenticated and authorized users can access course user data exports. Rate limiting and anomaly detection should be applied to prevent brute-force enumeration of course IDs. If possible, disable or restrict the export functionality until a secure patch is available. Employ web application firewalls (WAFs) to detect and block suspicious URL parameter manipulation attempts. Conduct thorough code reviews and penetration testing focusing on IDOR vulnerabilities across all endpoints handling sensitive data. Educate administrators about monitoring logs for unusual access patterns related to course data exports. Coordinate with Educativa for timely patch deployment once available. Additionally, consider encrypting sensitive data at rest and in transit to reduce exposure risk. Finally, review and update privacy policies and incident response plans to prepare for potential data breach scenarios.

Description

Insecure Direct Object Reference (IDOR) vulnerability in Campus Educativa specifically at the endpoint '/administracion/admin_usuarios.cgi?filtro_estado=T&wAccion=listado_xlsx&wBuscar=&wFiltrar=&wOrden=alta_usuario&wid_cursoActual=[ID]' where the data of users enrolled in the course is exported. Successful exploitation of this vulnerability could allow an unauthenticated attacker to access user data (e.g., usernames, first and last names, email addresses, and phone numbers) and retrieve the data of all users enrolled in courses by performing a brute-force attack on the course ID via a manipulated URL.

Impact

The primary impact of CVE-2026-3110 is the unauthorized disclosure of sensitive personal data of users enrolled in courses on the Educativa Campus platform. This breach of confidentiality can lead to privacy violations, identity theft, phishing campaigns, and social engineering attacks targeting affected individuals. Educational institutions using this platform may suffer reputational damage, legal consequences under data protection regulations (such as GDPR or local privacy laws), and loss of trust from students and staff. The ease of exploitation—requiring no authentication or user interaction—means attackers can automate data harvesting at scale, potentially compromising data for all courses hosted on vulnerable instances. While the vulnerability does not directly affect system integrity or availability, the exposure of personal data is critical in educational environments where privacy is paramount. Organizations worldwide using Educativa Campus or similar systems face increased risk of targeted attacks and regulatory scrutiny if this vulnerability remains unmitigated.

Pillar weaknessCWE Top 25 (2025): #19OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
