CVE-2025-23899 represents a medium-severity vulnerability that affects the Bookalet plugin for WordPress. This vulnerability allows for stored cross-site scripting (XSS) attacks, which could be exploited by malicious actors to execute arbitrary scripts in the context of users accessing the affected web application. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation.
The CVSS score for this vulnerability is 6.5, reflecting its medium severity level. This score is significant as it highlights the potential for attackers to exploit the vulnerability with low attack complexity and requires user interaction for successful exploitation. Given the nature of XSS vulnerabilities, organizations should prioritize addressing this issue to safeguard their web applications.
The urgency for defenders to act is underscored by the potential risk to organizations. Stored XSS vulnerabilities can lead to unauthorized access, data theft, and other security incidents, making it imperative for affected users to remediate this vulnerability promptly.
Organizations should prioritize patching immediately, particularly those using versions of the Bookalet plugin up to 1.0.3, as they are affected by this vulnerability.
The vulnerability was published on January 16, 2025, and the last modification occurred on April 23, 2026. As of now, there are no known public exploits or proofs of concept available, but the nature of the vulnerability necessitates immediate attention.
Vulnerability Details
The CVE-2025-23899 vulnerability is categorized as a stored cross-site scripting issue in the Bookalet plugin. It allows attackers to inject malicious scripts that can be executed in the context of the vulnerable application, affecting users who interact with the compromised site. The affected versions include all versions prior to 1.0.3.
This vulnerability has a CVSS score of 6.5, indicating a medium level of severity, with impacts on confidentiality, integrity, and availability classified as low. As such, organizations must remain vigilant and proactive in mitigating these vulnerabilities as part of their security posture.
Technical Analysis
The root cause of this vulnerability arises from improper handling of user input during web page generation, leading to the potential for stored XSS. Attackers can exploit this weakness remotely, requiring low privileges and user interaction to trigger the exploit. The attack complexity is considered low, as the exploitation can often be achieved through standard web interaction, such as visiting a maliciously crafted page or clicking on a deceptive link.
In terms of impact, confidentiality, integrity, and availability are all affected at a low level, meaning that while attackers may be able to execute scripts in the context of the user, the overall system may not be significantly compromised. However, the implications of XSS should not be underestimated, as they can lead to severe consequences, including session hijacking and unauthorized data access.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-23899 is substantial, particularly for organizations that rely on the Bookalet plugin for their operations. The potential for stored XSS can lead to severe consequences, including data breaches and loss of user trust. The blast radius for such vulnerabilities can extend beyond the immediate application, potentially affecting user accounts, sensitive data, and the organization's reputation.
Given the medium CVSS score of 6.5, organizations should address this vulnerability in their priority patch cycle. The ongoing threat landscape necessitates that organizations remain proactive in their cybersecurity efforts, particularly in light of emerging vulnerabilities that may exploit similar weaknesses.
