CVE-2025-61087 identifies a Cross Site Scripting (XSS) vulnerability in SourceCodester Pet Grooming Management Software version 1.0. The vulnerability exists specifically in the Customer Management Section, where the Customer Name field does not properly sanitize or validate user input. This allows an attacker to inject malicious scripts that can be executed in the context of the victim's browser when viewing the affected field. XSS vulnerabilities typically enable attackers to steal session cookies, perform actions on behalf of authenticated users, deface web content, or redirect users to malicious sites. Although the exact affected versions are not specified beyond version 1.0, the vulnerability is confirmed as published and reserved in late September 2025, with no CVSS score assigned yet and no known exploits in the wild. The lack of patches or mitigation links suggests that a fix may not yet be available or publicly disclosed. The vulnerability arises from insufficient input validation and output encoding in a web application module that manages customer data, a common vector for persistent or stored XSS attacks if the injected payload is saved and rendered to other users or administrators.

For European organizations using SourceCodester Pet Grooming Management Software 1.0, this XSS vulnerability could lead to significant risks including unauthorized access to user sessions, theft of sensitive customer data, and potential compromise of administrative accounts. Given that the affected module handles customer names, attackers could exploit this to target employees or customers viewing these records, potentially leading to phishing or social engineering attacks. The impact extends to reputational damage, regulatory non-compliance (especially under GDPR if personal data is exposed), and operational disruption if attackers leverage the vulnerability to escalate privileges or implant further malware. While no active exploits are reported, the presence of an unpatched XSS flaw in customer management software used in service industries like pet grooming could be attractive to attackers aiming to compromise smaller businesses or their clients. The threat is heightened if the software is accessible over the internet or within poorly segmented internal networks.

Organizations should immediately review and restrict access to the Customer Management Section of the software, especially limiting permissions to trusted personnel. Input validation and output encoding should be implemented or enhanced to sanitize the Customer Name field, ensuring that any HTML or script tags are neutralized before storage or rendering. Until an official patch is released, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting this field. Conduct code audits and penetration testing focused on input handling in the affected module. Additionally, educate users and administrators about the risks of clicking suspicious links or executing unexpected scripts within the application interface. Regular backups and monitoring for unusual activity can help detect exploitation attempts early. If feasible, isolate or segment the application environment to reduce exposure. Finally, maintain communication with the software vendor for updates and patches addressing this vulnerability.
