The vulnerability identified as CVE-2025-50020 pertains to an improper neutralization of input during web page generation, specifically a stored Cross-site Scripting (XSS) vulnerability in the Nitin Yawalkar RDFa Breadcrumb plugin. This vulnerability permits attackers to inject malicious scripts into web pages, impacting users and potentially leading to unauthorized actions or data theft.
With a CVSS score of 5.9, this vulnerability is classified as medium severity. It is crucial for organizations to recognize the potential risk associated with this vulnerability as it could lead to significant impacts, including data leakage or manipulation. Given that it is categorized under CWE-79, organizations should be aware that Cross-site Scripting vulnerabilities are often exploited by attackers to execute scripts in the context of a user’s session.
The Nitin Yawalkar RDFa Breadcrumb plugin versions from n/a to 2.3 are affected. As this issue has been deferred, the urgency of addressing it should be assessed based on the context of the specific deployment. Organizations should keep a close watch on updates and patches related to this vulnerability.
Organizations should prioritize patching immediately to mitigate risks associated with CVE-2025-50020. Failure to address this vulnerability could expose systems to potential exploitation, leading to severe consequences.
Vulnerability Details
The official description of CVE-2025-50020 indicates that it allows stored XSS in the Nitin Yawalkar RDFa Breadcrumb plugin. The vulnerability was published on June 20, 2025, and is characterized by a CVSS score of 5.9, indicating medium severity. The attack vector is classified as network-based, requiring a high level of privileges and user interaction. The vulnerability exposes low confidentiality, integrity, and availability impacts.
Technical Analysis
The root cause of CVE-2025-50020 lies in the improper validation and sanitization of user inputs during the web page generation process. Attackers may leverage this vulnerability to inject malicious scripts that execute in the context of the user's session. The attack complexity is low, making it easier for attackers to exploit this vulnerability, especially given the high privileges required for execution.
No user interaction is required for the exploitation of this vulnerability, as it can be triggered by simply navigating to the affected page. The potential impacts on confidentiality, integrity, and availability are all classified as low, but organizations should not underestimate the potential for exploitation.
Risk & Impact Analysis
Real-world deployment of the Nitin Yawalkar RDFa Breadcrumb plugin can expose organizations to significant risks due to CVE-2025-50020. The potential blast radius for this vulnerability is concerning, as attackers could exploit it to perform actions on behalf of users, leading to unauthorized access to sensitive information. Organizations utilizing this plugin must assess their risk posture, especially if user-generated content is involved.
The urgency for organizations to address this vulnerability is medium. Organizations should schedule remediation as part of their patch management cycle, particularly for systems that rely on the RDFa Breadcrumb plugin. Given the low EPSS score of 0.0017, the likelihood of exploitation remains low, but vigilance is essential.
