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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: 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.

Detectable: no evidence on record.
No public nuclei template indexed

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 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.

What to do

Upgrade Quiz Maker (WordPress plugin) to 6.7.0.89.

AI-suggested

European organizations should immediately verify if they use the Quiz Maker WordPress plugin and identify the installed version. If running a version prior to 6.7.0.89, they should prioritize upgrading to the latest patched version as soon as it becomes available. Until patched, administrators should restrict plugin access to only the most trusted users and consider temporarily disabling the plugin if feasible. Implementing strict role-based access controls (RBAC) to limit the number of users with high privileges can reduce exploitation risk. Additionally, applying Web Application Firewall (WAF) rules that detect and block suspicious script injections in plugin settings fields may provide interim protection. Regularly auditing plugin settings for unexpected or suspicious content can help detect exploitation attempts early. Organizations should also ensure their WordPress core and all plugins are kept up to date and monitor security advisories from plugin developers and WPScan. For multisite setups, extra caution is advised to monitor cross-site contamination and enforce strict user permissions. Finally, educating administrators about the risks of stored XSS and safe plugin configuration practices will help mitigate human error.

Description

CVE-2025-14579 is a medium severity Stored Cross-Site Scripting (XSS) vulnerability in the Quiz Maker WordPress plugin versions before 6.7.0.89. It arises because certain plugin settings are not properly sanitized or escaped, allowing high privilege users such as administrators to inject malicious scripts. This vulnerability can be exploited even when the unfiltered_html capability is disabled, such as in multisite WordPress setups. Exploitation requires high privileges and user interaction, and it can lead to limited confidentiality and integrity impacts, but no direct availability impact. No known exploits are currently reported in the wild. European organizations using affected versions of Quiz Maker, especially those with multisite WordPress deployments, should prioritize patching or mitigating this issue to prevent potential stored XSS attacks that could compromise administrative sessions or site content.

Impact

For European organizations, the primary impact of CVE-2025-14579 lies in the potential compromise of administrative accounts and site integrity on WordPress sites using the vulnerable Quiz Maker plugin. Stored XSS in administrative settings can lead to session hijacking, unauthorized changes to site content or configuration, and potential lateral movement within the CMS environment. While the vulnerability does not directly impact availability, the integrity and confidentiality of sensitive data and administrative controls can be undermined. Organizations operating multisite WordPress installations are particularly at risk since the vulnerability bypasses unfiltered_html restrictions typically used to mitigate XSS risks. This could lead to broader compromise across multiple sites managed under a single WordPress instance. Given the widespread use of WordPress in Europe for business, education, and government websites, exploitation could result in reputational damage, data breaches, and compliance issues under regulations such as GDPR if personal data is exposed or manipulated. The lack of known exploits reduces immediate risk, but the medium severity and ease of exploitation by high privilege users necessitate prompt attention.
