CVE-2025-62892 identifies a missing authorization vulnerability in the Sunshine Photo Cart software, specifically affecting versions up to and including 3.5.3. The core issue is that certain functionalities within the application are not properly constrained by Access Control Lists (ACLs), allowing users or attackers to access features or perform actions without the necessary permissions. This type of vulnerability typically arises from inadequate enforcement of authorization checks on server-side functions, which can lead to privilege escalation or unauthorized operations. Sunshine Photo Cart is an e-commerce platform tailored for photo sales and management, meaning the vulnerability could expose sensitive customer data, order information, or administrative functions. Although no public exploits have been reported yet, the lack of authorization checks makes this vulnerability relatively straightforward to exploit, especially if the attacker has some level of access to the system. The absence of a CVSS score indicates that the vulnerability is newly published and has not yet undergone formal severity assessment. The vulnerability was reserved and published in late October 2025, with Patchstack as the assigner. No patches or mitigations have been officially released at the time of this report, increasing the urgency for affected organizations to implement interim controls. The vulnerability’s impact depends on the deployment context, but unauthorized access to e-commerce functions can lead to data breaches, fraudulent transactions, or disruption of services.

For European organizations using Sunshine Photo Cart, this vulnerability poses significant risks including unauthorized access to customer data, order manipulation, and potential administrative control takeover. Such breaches could lead to financial losses, reputational damage, and regulatory penalties under GDPR due to exposure of personal data. E-commerce platforms are attractive targets for cybercriminals, and exploitation could facilitate fraudulent purchases, data theft, or service disruption. The impact is heightened in sectors with high transaction volumes or sensitive customer information, such as photography studios, event organizers, or retailers specializing in photo products. Additionally, unauthorized access could enable attackers to implant further malware or pivot within the network, increasing the scope of compromise. The lack of authentication requirements for exploitation broadens the threat landscape, making even external attackers a concern. Overall, the vulnerability undermines the integrity and confidentiality of affected systems, with potential availability impacts if attackers disrupt services.

Immediate mitigation should focus on identifying all instances of Sunshine Photo Cart within the organization’s infrastructure and restricting access to the application to trusted users and networks only. Implement network segmentation and firewall rules to limit exposure, especially from external sources. Monitor logs and user activity for unusual access patterns or unauthorized operations. Until official patches are released, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block attempts to access unauthorized functions. Review and tighten ACL configurations where possible, and enforce multi-factor authentication for administrative access to reduce risk. Engage with the vendor or community for updates on patch availability and apply them promptly once released. Conduct security awareness training for staff to recognize potential exploitation attempts. Finally, prepare incident response plans tailored to potential exploitation scenarios involving this vulnerability.
