CVE-2025-61456 is a reflected Cross-Site Scripting (XSS) vulnerability identified in the Bhabishya-123 E-commerce platform version 1.0. The vulnerability resides in the index endpoint, where the /index parameter accepts user input that is not properly sanitized or encoded before being reflected in the HTML response. This lack of input validation allows attackers to inject malicious JavaScript code that executes in the context of the victim's browser when they access a crafted URL or submit a manipulated request. The vulnerability enables attackers to perform actions such as stealing session cookies, redirecting users to malicious sites, defacing web content, or executing arbitrary scripts that compromise user data confidentiality and integrity. No CVSS score has been assigned yet, and no public exploits have been reported, but the vulnerability is publicly disclosed and considered exploitable due to the nature of reflected XSS attacks. The absence of patches or mitigation details in the provided information suggests that affected organizations must proactively implement security controls. The vulnerability affects all users interacting with the vulnerable endpoint, potentially impacting a wide user base. The technical details confirm the vulnerability's publication and reservation dates but lack further exploit or patch information.

For European organizations using Bhabishya-123 E-commerce 1.0, this XSS vulnerability could lead to significant risks including theft of user credentials, session hijacking, unauthorized actions performed on behalf of users, and erosion of customer trust due to potential website defacement or phishing attacks. The exploitation of this vulnerability could compromise the confidentiality and integrity of customer data, leading to regulatory compliance issues under GDPR. Additionally, attackers could leverage the vulnerability to distribute malware or conduct further attacks within the victim's network. The reflected nature of the XSS means that attacks require user interaction, but given the common use of URLs in marketing and customer communications, the attack surface is broad. The lack of authentication requirements lowers the barrier for exploitation, increasing risk. The availability impact is generally low, but reputational damage and potential legal consequences could be severe for affected organizations.

Organizations should immediately audit the input handling of the /index parameter in the Bhabishya-123 E-commerce platform and implement strict input validation and output encoding to neutralize malicious scripts. Employing context-aware encoding (e.g., HTML entity encoding) before reflecting user input in responses is critical. Additionally, deploying a robust Content Security Policy (CSP) can help restrict the execution of unauthorized scripts. Web Application Firewalls (WAFs) should be configured to detect and block common XSS attack patterns targeting this endpoint. Regular security testing, including automated scanning and manual penetration testing focused on input validation, should be conducted. Organizations should monitor web traffic for suspicious requests and educate users about the risks of clicking on untrusted links. If possible, upgrading to a patched version of the platform or applying vendor-provided fixes is recommended once available. Logging and alerting mechanisms should be enhanced to detect exploitation attempts promptly.
