Scope: Unchanged
Confidentiality: None
Integrity: Low
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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 Jan 2024
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. Immediate mitigation involves updating the EventON Premium plugin to the latest version once a patch addressing CVE-2024-0237 is released. Monitor official plugin channels for security updates. 2. Until a patch is available, restrict access to the AJAX endpoints by implementing web application firewall (WAF) rules that block unauthenticated requests to the vulnerable AJAX actions. 3. Employ strict access control measures on the WordPress site, including limiting plugin management capabilities to trusted administrators only. 4. Monitor event configurations and logs for unusual changes or access patterns that could indicate exploitation attempts. 5. Consider disabling or replacing the EventON Premium plugin if virtual event integrity is critical and no immediate patch is available. 6. Harden the WordPress environment by ensuring all plugins and themes are regularly updated, and unnecessary plugins are removed to reduce attack surface. 7. Educate event organizers and participants about verifying event details through official channels to mitigate risks from manipulated event information.

Description

The EventON WordPress plugin through 4.5.8, EventON WordPress plugin before 2.2.7 do not have authorisation in some AJAX actions, allowing unauthenticated users to update virtual events settings, such as meeting URL, moderator, access details etc

Impact

For European organizations using the EventON Premium plugin on their WordPress sites, this vulnerability poses a risk to the integrity of virtual event data. Organizations that rely on EventON for scheduling and managing online meetings, webinars, or conferences could face unauthorized changes to event URLs, moderators, or access credentials. This could lead to confusion among participants, unauthorized access to meetings if URLs or access details are manipulated, or reputational damage if event information is tampered with. While the vulnerability does not directly expose sensitive data or cause denial of service, the manipulation of event settings could be leveraged in social engineering or phishing campaigns targeting attendees. Sectors with frequent virtual events, such as education, professional services, and public sector entities, may be particularly impacted. The risk is heightened in environments where event security is critical, such as government or healthcare organizations conducting confidential meetings. Given the network-exploitable nature and lack of required authentication, attackers can easily target vulnerable sites, increasing the threat surface for European organizations using this plugin.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #4OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
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.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
