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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

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

Organizations should immediately identify if they use any affected versions of the AYS Pro Plugins Quiz Maker (Business ≤8.8.0, Developer ≤21.8.0, Agency ≤31.8.0). Since no official patches are currently linked, temporary mitigations include disabling or restricting access to the vulnerable shortcode execution functionality, such as limiting who can submit inputs that trigger do_shortcode or applying web application firewall (WAF) rules to detect and block suspicious shortcode patterns. Administrators should monitor plugin updates from AYS Pro Plugins for official patches and apply them promptly once available. Additionally, implementing strict input validation and sanitization at the application level can reduce risk. Regular security audits and monitoring for unusual shortcode activity or unauthorized changes can help detect exploitation attempts early. Employing the principle of least privilege for WordPress users and plugins can limit the damage if exploitation occurs.

Description

The Quiz Maker Business, Developer, and Agency plugins for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 8.8.0 (Business), up to, and including, 21.8.0 (Developer), and up to, and including, 31.8.0 (Agency). This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

Impact

The vulnerability allows unauthenticated remote attackers to execute arbitrary shortcodes, potentially leading to unauthorized code execution, data leakage, content manipulation, or denial of service on affected WordPress sites. This can compromise the confidentiality of sensitive data, integrity of site content and configurations, and availability of the service. Organizations relying on the affected Quiz Maker plugins risk website defacement, data breaches, or full site takeover. Given WordPress's widespread use, exploitation could affect a large number of websites, including those of businesses, educational institutions, and agencies using these plugins for quizzes and assessments. The lack of authentication and user interaction requirements lowers the barrier for attackers, increasing the likelihood of exploitation if unpatched. The impact extends to reputational damage, regulatory compliance violations, and operational disruptions.

CWE-95Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') (opens in a new tab)
Variant weaknessLikelihood of exploit: MediumOWASP Top 10 A05:2025: Injection (opens in a new tab)
The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval").
Architecture and Design · Implementation · Refactoring
If possible, refactor your code so that it does not need to use eval() at all.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Implementation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180, CWE-181). Make sure that your application does not inadvertently decode the same input twice (CWE-174).
