CVE-2024-44045 identifies a stored cross-site scripting (XSS) vulnerability in the WP Abstracts plugin by Kevon Adonis, specifically in the wp-abstracts-manuscripts-manager component. This vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be stored persistently on the server and executed in the browsers of users who view the affected pages. The vulnerability affects all versions up to and including 2.6.5. Stored XSS is particularly dangerous because the malicious payload remains on the server and can impact multiple users without requiring repeated exploitation. Attackers can leverage this flaw to steal session cookies, perform actions on behalf of authenticated users, deface websites, or redirect users to malicious domains. The vulnerability does not require prior authentication or user interaction beyond visiting a compromised page, increasing its exploitability. No CVSS score has been assigned yet, and no known exploits have been reported in the wild. The lack of official patches at the time of publication necessitates proactive mitigation. The plugin is commonly used in WordPress environments for managing abstracts and manuscripts, often in academic or conference settings, making those sectors particularly vulnerable. The vulnerability highlights the importance of proper input validation and output encoding in web application development to prevent injection attacks.

The impact of CVE-2024-44045 can be significant for organizations using the WP Abstracts plugin, especially those managing academic conferences, journals, or events. Successful exploitation can lead to the execution of arbitrary JavaScript in users' browsers, resulting in session hijacking, credential theft, unauthorized actions, or distribution of malware. This can compromise user data confidentiality and integrity, damage organizational reputation, and lead to regulatory compliance issues if sensitive data is exposed. Since the vulnerability is stored XSS, it can affect multiple users over time, amplifying the potential damage. Additionally, attackers could use the vulnerability as a foothold to launch further attacks against the hosting environment or connected systems. Organizations relying on this plugin should consider the risk to their user base and the potential for widespread impact if exploited. The absence of known exploits currently provides a window for remediation before active attacks emerge.

Organizations should immediately audit their WordPress installations to identify if the WP Abstracts plugin version 2.6.5 or earlier is in use. Until an official patch is released, administrators should consider disabling or removing the plugin to eliminate exposure. If removal is not feasible, implement strict input validation and output encoding on all user-supplied data related to abstracts and manuscripts to prevent script injection. Employ Web Application Firewalls (WAFs) with rules targeting common XSS payloads to provide an additional layer of defense. Monitor logs and user reports for suspicious activity or unexpected script execution. Educate users about the risks of XSS and encourage cautious behavior when interacting with abstracts or manuscript pages. Stay alert for vendor updates or patches and apply them promptly once available. Additionally, consider isolating the plugin's functionality or restricting access to trusted users to minimize exposure. Regular security assessments and penetration testing focusing on input handling can help detect similar vulnerabilities proactively.
