CVE-2025-50020 describes a stored cross-site scripting vulnerability in the RDFa Breadcrumb plugin by Nitin Yawalkar, present in versions up to 2.3. The issue is due to improper neutralization of input during web page generation, which can lead to malicious script injection that persists and executes in users' browsers. The vulnerability has a CVSS 3.1 base score of 5.9 (medium), with attack vector network, low attack complexity, high privileges required, user interaction required, and impacts on confidentiality, integrity, and availability classified as low. No patch or vendor advisory information is provided, and no known exploitation in the wild has been reported.

Successful exploitation allows an attacker with high privileges and requiring user interaction to inject and store malicious scripts in the web pages generated by the RDFa Breadcrumb plugin. This can lead to limited compromise of confidentiality, integrity, and availability of affected systems or user data. The medium CVSS score reflects the moderate risk posed by this vulnerability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict high-privilege user access to the affected plugin and avoid actions that could trigger stored XSS payloads. Monitor vendor communications for updates on patches or mitigations.
