CVE-2025-11051 is a Cross-Site Request Forgery (CSRF) vulnerability identified in version 1.0 of the SourceCodester Pet Grooming Management Software. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unauthorized requests to a web application in which they are currently authenticated. This particular vulnerability is remotely exploitable without requiring any privileges or prior authentication, and it requires user interaction (such as clicking a malicious link or visiting a crafted webpage). The CVSS 4.0 base score is 5.3, indicating a medium severity level. The attack vector is network-based with low attack complexity and no privileges required. The impact primarily affects the integrity of the application, with limited impact on confidentiality and availability. The vulnerability does not require any special conditions such as scope changes or user authentication, but it does require user interaction. Although the exact affected code or functionality within the software is unspecified, the vulnerability allows an attacker to perform unauthorized actions on behalf of legitimate users, potentially manipulating data or settings within the pet grooming management system. No known exploits are currently reported in the wild, and no patches or mitigations have been officially published at this time.

For European organizations using SourceCodester Pet Grooming Management Software version 1.0, this vulnerability could lead to unauthorized actions being performed within their management systems. This may include manipulation of customer data, appointment schedules, billing information, or other operational data critical to business continuity. The integrity of the system is at risk, which could undermine trust with customers and partners. While the vulnerability does not directly impact confidentiality or availability, the unauthorized changes could cause operational disruptions or financial discrepancies. Given the software’s niche application in pet grooming businesses, the impact is likely limited to small and medium enterprises in this sector. However, any disruption or data manipulation could have reputational consequences and potential regulatory implications under GDPR if personal data is affected. The remote and unauthenticated nature of the exploit increases the risk, especially if users are tricked into interacting with malicious content.

To mitigate this CSRF vulnerability, organizations should implement anti-CSRF tokens in all state-changing requests within the application. This involves embedding unique, unpredictable tokens in forms and verifying them on the server side before processing requests. Additionally, enforcing the SameSite cookie attribute to 'Strict' or 'Lax' can reduce the risk of CSRF by restricting cross-origin requests. Organizations should also ensure that users are educated about the risks of clicking on suspicious links or visiting untrusted websites. Network-level protections such as web application firewalls (WAFs) can be configured to detect and block suspicious CSRF attack patterns. Since no official patch is currently available, organizations should monitor vendor communications for updates and apply patches promptly once released. If feasible, upgrading to a newer, unaffected version of the software or switching to alternative solutions with better security postures is advisable. Regular security assessments and penetration testing focusing on web application vulnerabilities can help identify and remediate similar issues proactively.
