CVE-2025-47615 is a medium-severity vulnerability classified under CWE-79, which pertains to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This specific vulnerability affects the 'Amazon Product in a Post' component developed by flowdee, up to version 5.2.2. The vulnerability is a Stored XSS, meaning that malicious input is persistently stored by the application and later rendered in web pages without proper sanitization or encoding. This allows an attacker to inject malicious scripts that execute in the context of users' browsers when they view the affected pages. The CVSS 3.1 base score is 5.9, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L) shows that the attack can be performed remotely over the network with low attack complexity but requires high privileges and user interaction. The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component. The impact affects confidentiality, integrity, and availability at a low level. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability was published on May 7, 2025, and has been enriched by CISA, indicating recognition by US cybersecurity authorities. Stored XSS vulnerabilities can be leveraged to hijack user sessions, deface websites, redirect users to malicious sites, or deliver malware payloads, posing significant risks especially in environments where sensitive user data or administrative functions are accessible via the vulnerable component.

For European organizations using the 'Amazon Product in a Post' plugin by flowdee, this vulnerability could lead to unauthorized script execution in users' browsers, potentially compromising user credentials, session tokens, or other sensitive information. Given that this is a stored XSS, the malicious payload can affect all users who access the compromised content, amplifying the impact. This can damage organizational reputation, lead to data breaches under GDPR regulations, and cause service disruptions if attackers exploit the vulnerability to deface or manipulate website content. The requirement for high privileges to exploit somewhat limits the attack surface to users with elevated access, such as content managers or administrators, but the scope change indicates that exploitation could affect other components or users beyond the initial vector. European e-commerce platforms, marketing sites, or content management systems integrating this plugin are particularly at risk. The vulnerability could also be used as a stepping stone for further attacks within the network, especially if combined with social engineering to trick users into executing malicious scripts.

1. Immediate mitigation should include restricting access to the vulnerable plugin to trusted users only, minimizing the number of users with high privileges who can input content. 2. Implement strict input validation and output encoding on all user-supplied data within the 'Amazon Product in a Post' component to neutralize malicious scripts. 3. Monitor and audit content submitted through this plugin for suspicious or unexpected scripts or HTML tags. 4. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5. Since no official patches are currently linked, consider disabling or removing the plugin until a vendor patch is released. 6. Educate privileged users about the risks of injecting untrusted content and enforce multi-factor authentication to reduce the risk of compromised accounts. 7. Regularly update and review all third-party plugins and components for vulnerabilities and apply patches promptly once available. 8. Use web application firewalls (WAFs) with rules targeting XSS payloads to provide an additional layer of defense.
