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.

Exploitation evidence

Disclosed: evidence found.
CVE published 22 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

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 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 should include restricting admin access strictly to trusted personnel and enforcing strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of credential compromise. 2. Monitor and audit all changes to plugin settings and administrative inputs for suspicious or unexpected content that could indicate attempted exploitation. 3. Until an official patch is released, consider disabling or removing the Product Enquiry for WooCommerce plugin if it is not critical to business operations. 4. Implement Web Application Firewall (WAF) rules to detect and block common XSS payloads targeting the plugin’s settings fields. 5. For multisite WordPress environments, review and tighten capability assignments and consider additional input sanitization at the network level. 6. Stay updated with vendor announcements and apply patches promptly once available. 7. Conduct regular security training for administrators to recognize and avoid introducing malicious content. 8. Utilize security plugins that can scan for stored XSS payloads in the database and sanitize output dynamically as an interim safeguard.

Description

The Product Enquiry for WooCommerce WordPress plugin before 3.1 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

Impact

For European organizations, especially those operating e-commerce websites using WooCommerce with the Product Enquiry plugin, this vulnerability poses a risk of stored XSS attacks that can compromise administrative sessions or inject malicious scripts into the site. This could lead to unauthorized access to sensitive customer data, manipulation of product inquiries, or defacement of the online storefront, damaging brand reputation and customer trust. Multisite WordPress setups, common in large enterprises or agencies managing multiple sites, are particularly vulnerable since the usual HTML filtering protections can be bypassed. Given the GDPR requirements in Europe, any data breach or unauthorized data access resulting from exploitation could lead to regulatory penalties and legal consequences. Although exploitation requires admin privileges, insider threats or compromised admin accounts could leverage this vulnerability to escalate attacks. The medium severity score indicates moderate risk, but the potential impact on confidentiality and integrity in a commercial context is significant.

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.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
