CVE-2025-49312: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in CodeRevolution Echo RSS Feed Post Generator Plugin for WordPress
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in CodeRevolution Echo RSS Feed Post Generator Plugin for WordPress allows Reflected XSS. This issue affects Echo RSS Feed Post Generator Plugin for WordPress: from n/a through 5.4.8.1.
AI Analysis
Technical Summary
CVE-2025-49312 is a high-severity reflected Cross-Site Scripting (XSS) vulnerability identified in the Echo RSS Feed Post Generator Plugin for WordPress, developed by CodeRevolution. This vulnerability arises due to improper neutralization of user input during web page generation, classified under CWE-79. Specifically, the plugin fails to adequately sanitize or encode input data that is reflected back in HTTP responses, allowing an attacker to inject malicious scripts. The affected versions include all versions up to and including 5.4.8.1. The vulnerability has a CVSS 3.1 base score of 7.1, indicating a high impact with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L. This means the attack can be executed remotely over the network without any privileges, requires user interaction (e.g., victim clicking a crafted link), and the scope is changed, implying that the vulnerability affects components beyond the initially vulnerable plugin, potentially impacting the entire WordPress site. The impact includes limited confidentiality, integrity, and availability losses, such as theft of session cookies, defacement, or redirection to malicious sites. No known exploits in the wild have been reported yet, and no official patches have been released at the time of publication (June 17, 2025). The vulnerability is particularly relevant for websites using this plugin, which is designed to generate posts from RSS feeds, a common functionality for content aggregation and syndication in WordPress environments.
Potential Impact
For European organizations, this vulnerability poses a significant risk to websites utilizing the Echo RSS Feed Post Generator Plugin. Successful exploitation could lead to session hijacking, unauthorized actions performed on behalf of users, or distribution of malware through compromised web pages. This can damage organizational reputation, lead to data breaches involving user information, and disrupt business operations. Given the reflected XSS nature, phishing campaigns could be enhanced by embedding malicious scripts in URLs, increasing the risk of credential theft or malware installation. Organizations in sectors with high regulatory scrutiny, such as finance, healthcare, and e-commerce, may face compliance violations under GDPR if personal data is compromised. Additionally, the scope change in the CVSS vector suggests that the vulnerability could affect other components or plugins interacting with the Echo RSS Feed Post Generator, potentially amplifying the impact. The lack of patches and known exploits means organizations must proactively mitigate the risk to prevent exploitation, especially as attackers often weaponize such vulnerabilities rapidly after disclosure.
Mitigation Recommendations
1. Immediate mitigation should include disabling or uninstalling the Echo RSS Feed Post Generator Plugin until a security patch is released by CodeRevolution. 2. Employ Web Application Firewalls (WAFs) with updated rules to detect and block reflected XSS attack patterns targeting this plugin. 3. Implement strict Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected web pages. 4. Conduct thorough input validation and output encoding on all user-supplied data, especially in custom code interacting with the plugin or RSS feed inputs. 5. Monitor web server logs and security alerts for unusual URL parameters or repeated attempts to exploit reflected XSS vectors. 6. Educate users and administrators about the risks of clicking suspicious links and encourage the use of multi-factor authentication to reduce the impact of session hijacking. 7. Once available, promptly apply official patches or updates from the vendor. 8. Review and audit other plugins and themes for similar input handling weaknesses to prevent chained attacks. 9. For organizations with high-risk profiles, consider isolating WordPress instances or using containerization to limit the blast radius of potential exploitation.
