CVE-2025-49301: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in wpsoul Greenshift
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in wpsoul Greenshift allows DOM-Based XSS. This issue affects Greenshift: from n/a through 11.5.5.
AI Analysis
Technical Summary
CVE-2025-49301 is a DOM-based Cross-site Scripting (XSS) vulnerability identified in the wpsoul Greenshift product, affecting versions up to 11.5.5. This vulnerability arises from improper neutralization of input during web page generation, classified under CWE-79. Specifically, the issue allows malicious actors to inject and execute arbitrary scripts within the context of a victim's browser by manipulating the Document Object Model (DOM). The vulnerability requires network access (AV:N), low attack complexity (AC:L), and privileges (PR:L), with user interaction (UI:R) necessary to trigger the exploit. The scope is changed (S:C), indicating that the vulnerability can affect resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability impacts, but the combined effect can lead to unauthorized actions or data exposure within the application context. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on June 6, 2025, and has a CVSS v3.1 base score of 6.5, categorized as medium severity. The vulnerability is significant because DOM-based XSS can bypass traditional input validation and content security policies if not properly mitigated, leading to session hijacking, defacement, or redirection attacks. Greenshift is a WordPress theme or plugin product by wpsoul, commonly used in website development, making this vulnerability relevant to web applications relying on this software for content presentation and user interaction.
Potential Impact
For European organizations using wpsoul Greenshift, this vulnerability poses a risk of client-side attacks that can compromise user sessions, steal sensitive information, or perform unauthorized actions on behalf of users. Given the medium severity and requirement for user interaction, the threat is more pronounced for organizations with high web traffic and user engagement, such as e-commerce, media, and service providers. The vulnerability could undermine user trust and lead to reputational damage, regulatory scrutiny under GDPR if personal data is exposed, and potential financial losses from fraud or remediation costs. The cross-site scripting nature of the vulnerability also increases the risk of phishing campaigns leveraging compromised websites. Since no known exploits are currently in the wild, the immediate risk is moderate, but the potential for exploitation remains if attackers develop proof-of-concept code. Organizations relying on Greenshift should consider the impact on their web presence and user data confidentiality, especially if they operate in sectors with stringent data protection requirements.
Mitigation Recommendations
1. Immediate assessment of all web properties using wpsoul Greenshift to identify affected versions. 2. Monitor vendor communications and security advisories for official patches or updates addressing CVE-2025-49301. 3. Implement Web Application Firewall (WAF) rules specifically targeting DOM-based XSS patterns related to Greenshift to provide temporary protection. 4. Conduct thorough input validation and output encoding on all user-controllable inputs within the application, focusing on client-side scripts and DOM manipulations. 5. Employ Content Security Policy (CSP) headers with strict script-src directives to limit script execution sources and mitigate XSS impact. 6. Educate users and administrators about the risks of clicking suspicious links or interacting with untrusted content on affected sites. 7. Plan for timely patch deployment once available, including testing in staging environments to avoid service disruption. 8. Review and enhance logging and monitoring for unusual user activity or script injection attempts to detect exploitation attempts early.
