CVE-2025-49948 is a reflected Cross-site Scripting (XSS) vulnerability found in the WP Super Edit plugin for WordPress, developed by Ahmad Awais. The vulnerability arises from improper neutralization of user-supplied input during the generation of web pages, allowing attackers to inject malicious scripts that are reflected back to users. This flaw affects all versions of WP Super Edit up to and including 2.5.4. An attacker can craft a malicious URL or input that, when visited or processed by a victim's browser, executes arbitrary JavaScript in the context of the vulnerable website. The vulnerability does not require authentication (PR:N) but does require user interaction (UI:R), such as clicking a malicious link. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component. The CVSS v3.1 base score is 7.1, indicating a high severity due to the potential for partial confidentiality, integrity, and availability impacts. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk to WordPress sites using this plugin, especially those with high traffic or sensitive user data. The vulnerability was reserved in June 2025 and published in October 2025, with no patch links currently available, suggesting that remediation may still be pending or in progress.

For European organizations, this vulnerability can lead to the execution of malicious scripts in the browsers of site visitors or administrators, potentially resulting in session hijacking, theft of sensitive information such as cookies or credentials, defacement, or redirection to malicious sites. The partial compromise of confidentiality, integrity, and availability can affect customer trust, lead to data breaches under GDPR regulations, and cause reputational damage. Organizations relying on WP Super Edit for content editing on WordPress sites are at risk, particularly those in sectors like e-commerce, finance, healthcare, and government where data sensitivity and regulatory compliance are critical. The reflected nature of the XSS means phishing campaigns could leverage this vulnerability to target users. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score underscores the urgency. Additionally, the vulnerability’s ability to affect resources beyond the vulnerable component increases the potential attack surface and impact severity.

1. Monitor for official patches or updates from the WP Super Edit plugin developer and apply them immediately once available. 2. Until a patch is released, implement Web Application Firewalls (WAFs) with rules specifically targeting reflected XSS attacks to block malicious payloads. 3. Employ strict Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected sites. 4. Conduct thorough input validation and output encoding on all user-supplied data within the WordPress environment, especially in areas where WP Super Edit processes input. 5. Educate users and administrators about the risks of clicking unknown or suspicious links to reduce the likelihood of successful phishing leveraging this vulnerability. 6. Regularly audit WordPress plugins and remove or replace those that are unmaintained or have known vulnerabilities. 7. Use security plugins that can detect and mitigate XSS attacks dynamically. 8. Implement multi-factor authentication (MFA) for administrative access to reduce the risk of account compromise if session hijacking occurs.
