CVE-2025-61087 identifies a Cross Site Scripting (XSS) vulnerability in SourceCodester Pet Grooming Management Software version 1.0. The vulnerability arises from insufficient input sanitization in the Customer Name field within the Customer Management Section, allowing attackers to inject malicious JavaScript code. When a victim user views the affected field, the injected script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions within the application. The vulnerability is exploitable remotely over the network without requiring authentication, but it does require user interaction (e.g., the victim must view or interact with the maliciously crafted input). The CVSS v3.1 base score is 6.1, reflecting a medium severity level with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity, with no impact on availability. No patches or official fixes have been published yet, and no known exploits have been observed in the wild. The vulnerability is classified under CWE-79, which is a common and well-understood web application security issue. Organizations using this software should be aware of the risk of client-side script injection and the potential consequences of session compromise or data leakage.

For European organizations, the impact of CVE-2025-61087 depends largely on the extent of SourceCodester Pet Grooming Management Software deployment. The vulnerability could allow attackers to execute malicious scripts in the browsers of employees or customers who access the affected Customer Management Section, potentially leading to theft of session tokens, unauthorized actions, or data leakage. This can undermine the confidentiality and integrity of customer data and internal operations. While availability is not affected, the reputational damage and regulatory implications under GDPR for data breaches could be significant. Small and medium enterprises (SMEs) in the pet care sector, which often use niche management software, may be particularly vulnerable. The vulnerability could also be leveraged as a foothold for further attacks within corporate networks if attackers gain access through compromised user sessions. Given the medium severity and lack of authentication requirement, the risk is non-trivial but manageable with proper controls.

To mitigate CVE-2025-61087, organizations should implement strict input validation and output encoding on the Customer Name field to prevent injection of malicious scripts. Employing Content Security Policy (CSP) headers can reduce the impact of any injected scripts by restricting script execution sources. Web application firewalls (WAFs) can be configured to detect and block XSS payloads targeting this vulnerability. Since no official patch is available, organizations should consider temporary workarounds such as disabling or restricting access to the vulnerable Customer Management Section until a fix is released. Regular security training for users to recognize phishing or suspicious links can reduce the risk of user interaction-based exploitation. Monitoring logs for unusual activity related to the affected application can help detect exploitation attempts. Finally, organizations should maintain an inventory of software assets to identify and prioritize remediation of vulnerable systems.
