Exploitation Conditions

Exploitation targets the WP Crowdfunding plugin (Themeum) at versions 2.2.2 and earlier running on a WordPress site. No authentication is required (PR:N), but successful attack depends on user interaction (UI:R): a victim must be induced to click or load a crafted request, so the attacker needs a delivery vector such as phishing. The specific vulnerable parameter or feature is not described in the available sources. The primary limiting factor is the required victim interaction and the fact that impact is confined to the victim's browser session rather than the server itself; upgrading beyond 2.2.2 is the remediation path, though the exact fixed version is not specified in the provided data.

Impact

This is a moderate-severity reflected/unauthenticated Cross-Site Scripting flaw (CVSS 7.1, CWE-79) in the WP Crowdfunding WordPress plugin, reported by Patchstack and assigned a 'this_week' priority by the vuln.today decision framework. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L) describes a network-reachable, low-complexity issue that needs no privileges (PR:N) but does require user interaction (UI:R), and the changed scope (S:C) reflects that injected script executes in the victim's browser context rather than only the vulnerable component. No EPSS score, no CISA KEV listing, and no confirmed exploit code are present in the supplied data, so there is no public exploit identified at time of analysis and no evidence of active exploitation. The 'this_week' label and Patchstack sourcing indicate this should be remediated promptly as part of routine patching, but the signals do not point to an emergency: the UI:R requirement and the typical limited impact of XSS (C:L/I:L/A:L) make this a real-but-not-urgent priority rather than a high-CVSS issue with disproportionately low real risk. EPSS is simply absent here (not low), so no probabilistic exploitation estimate can be stated.

Exploit ScenarioDerived

An unauthenticated attacker crafts a malicious URL or request targeting the WP Crowdfunding plugin and lures a logged-in site visitor or administrator into clicking it; when the victim's browser loads the response, injected JavaScript executes in their session context. Because exploitation requires that user interaction (UI:R), the attacker must rely on phishing or social engineering, and no public exploit code has been identified at time of analysis.

AnalysisAIv1 – Oct 29, 2026

Unauthenticated cross-site scripting in WP Crowdfunding 2.2.2 and earlier lets remote attackers inject script that executes in a victim's browser when the victim is induced to load a crafted request. The flaw is rated CVSS 7.1 (CWE-79) and requires user interaction, so delivery depends on phishing or similar lures; no public exploit was identified at time of analysis, and it is not in CISA KEV. The vuln.today framework assigns this_week priority, and upgrading beyond 2.2.2 is the remediation path.

RemediationAI

Upgrade WP Crowdfunding to a version later than 2.2.2; the provided data does not specify the exact fixed version, and the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/wp-crowdfunding/vulnerability/wordpress-wp-crowdfunding-plugin-2-2-2-cross-site-scripting-xss-vulnerability?_s_id=cve is the reference for patch availability. Because exploitation requires victim interaction, the practical exposure is tied to lures that cause users to load a crafted request. No additional workarounds are specified in the available sources.

Technical ContextAI · show details

CVE-2026-42692 is a CWE-79 cross-site scripting issue in the Themeum WP Crowdfunding WordPress plugin, identified by CPE cpe:2.3:a:themeum:wp_crowdfunding. The independent assessment describes it as reflected/unauthenticated XSS with CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, meaning network delivery, no privileges required, mandatory victim interaction, scope change, and low confidentiality/integrity impact without availability impact. The specific vulnerable parameter or feature is not described in the available sources, so the exact injection point is not confirmed; impact is confined to the victim's browser session rather than the server.

Unauthenticated Cross Site Scripting (XSS) in WP Crowdfunding <= 2.2.2 versions.

Executive ViewAI

Why It Matters

WP Crowdfunding versions up to 2.2.2 contain an unauthenticated cross-site scripting flaw that could allow attackers to inject malicious scripts into users' browsers, potentially compromising session data or performing actions on behalf of victims. The vulnerability requires user interaction, such as clicking a crafted link, making phishing the primary attack vector. While no public exploit has been identified, the high severity rating and potential for reputational and operational impact warrant immediate attention from website administrators and security teams.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Implement WAF rules to filter malicious script injections, enforce strict input validation and output encoding via security plugins, and educate users about phishing risks; restrict plugin usage to trusted environments.
