Attack Vector: Network
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Unchanged
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: 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: 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 31 Dec 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.
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 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

European organizations should immediately verify if their WordPress installations use the Ultimate Post Kit Addons for Elementor plugin and identify the plugin version. If the version is prior to 4.0.16, they should upgrade to the latest version where the vulnerability is patched. In addition to patching, organizations should audit their WordPress configurations to restrict access to sensitive content and consider implementing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious AJAX requests targeting the vulnerable endpoints. Monitoring web server logs for unusual access patterns to AJAX endpoints can help detect exploitation attempts. Content access policies should be reviewed to ensure that private or unpublished posts are not inadvertently exposed through other plugins or custom code. For high-risk environments, consider temporarily disabling the affected plugin or its AJAX features until patched. Regular security assessments and plugin inventory management will help prevent similar risks in the future.

Description

The Ultimate Post Kit Addons for Elementor WordPress plugin before 4.0.16 exposes multiple AJAX “load more” endpoints such as upk_alex_grid_loadmore_posts without ensuring that posts to be displayed are published authentication. This allows an unauthenticated attacker to query arbitrary posts and retrieve rendered HTML content of private and unpublished ones.

Impact

For European organizations, this vulnerability poses a risk of unauthorized disclosure of sensitive or unpublished content hosted on WordPress sites using the Ultimate Post Kit Addons for Elementor plugin. This could lead to leakage of confidential business information, intellectual property, or personal data, potentially violating GDPR and other data protection regulations. The exposure of unpublished content might also damage organizational reputation or provide attackers with reconnaissance information for further attacks. Since the vulnerability does not affect integrity or availability, the primary concern is confidentiality. Organizations in sectors such as media, publishing, legal, and government that rely on WordPress for content management are particularly at risk. The ease of exploitation without authentication increases the threat level, especially for public-facing websites. However, the absence of known exploits in the wild suggests that immediate widespread attacks are not yet observed, but proactive mitigation is recommended.

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.
