CVE-2025-23792 is a high-severity vulnerability classified as Cross-site Scripting (XSS) within the WP Busters Passwordless WP plugin. This vulnerability allows improper neutralization of input during web page generation, particularly permitting reflected XSS attacks against users. This issue affects versions of the Passwordless WP plugin from an unknown state up to and including version 1.1.6. With a CVSS score of 7.1, organizations utilizing this plugin should take note of the potential impact on their applications.
Risk to organizations includes unauthorized access to sensitive user data, which could lead to further attacks or exploitation. The vulnerability is categorized as having a low complexity and does not require any privileges for exploitation, but it does require user interaction. The status of this CVE is marked as deferred, indicating that it may not be actively being exploited at this time, but organizations should remain vigilant.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability. The availability of a fix or update is crucial to preventing potential exploitation.
Given the nature of XSS vulnerabilities, attackers may leverage this weakness to execute malicious scripts in the context of the user’s browser. This can allow them to steal session cookies, deface web content, or redirect users to malicious sites. Therefore, it is essential for organizations to assess their exposure and implement appropriate remediation strategies.
Vulnerability Details
The vulnerability is classified under CWE-79, which indicates improper neutralization of input during web page generation. The CVSS score of 7.1 signifies a high severity level, indicating that organizations need to take prompt action. The affected product is WP Busters Passwordless WP, specifically version 1.1.6 and earlier. The vulnerability was published on January 27, 2025, and has a potential impact on confidentiality, integrity, and availability, all marked as low.
Technical Analysis
The root cause of CVE-2025-23792 lies in improper handling of user input that is subsequently reflected back to the user without adequate validation or sanitization. This vulnerability's attack vector is network-based, meaning an attacker can exploit it remotely. The attack complexity is low, and no privileges are required to initiate the attack. User interaction is necessary, as an attacker must lure the user to click on a malicious link or visit a compromised web page. The impact on confidentiality and integrity is low, while availability is also minimally affected.
Risk & Impact Analysis
Real-world deployment risk associated with this vulnerability includes the potential for attackers to execute scripts that can hijack user sessions and compromise sensitive information. Given that the attack complexity is low and user interaction is required, the blast radius could extend significantly if a user is tricked into executing malicious payloads. Organizations should address this vulnerability in their priority patch cycle, considering its potential impact on user trust and data security.
Exploitation Status
Signal | Status |
|---|---|
