CVE-2025-68566 is a Stored Cross-Site Scripting (XSS) vulnerability identified in the wphocus My auctions allegro WordPress plugin, affecting versions up to and including 3.6.32. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be stored persistently within the application. When a victim user accesses the affected page, the malicious script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed with the victim's privileges. The CVSS 3.1 base score is 5.4 (medium severity), reflecting that the attack vector is network-based and requires low attack complexity, but does require privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), indicating the vulnerability can affect components beyond the initially vulnerable module. Confidentiality and integrity impacts are low, while availability is unaffected. No public exploits are currently known, but the vulnerability is publicly disclosed as of December 24, 2025. The plugin is commonly used in WordPress environments to facilitate auction functionalities, making it a target for attackers seeking to compromise e-commerce or auction sites. The vulnerability's exploitation requires an attacker to have some level of authenticated access to inject the malicious payload, which then executes when other users view the affected content. This type of vulnerability is particularly dangerous in multi-user environments where users have varying privilege levels. The lack of an official patch link suggests that remediation is pending or in progress. Organizations should monitor vendor communications closely and prepare to deploy updates promptly once available.

For European organizations, the impact of CVE-2025-68566 can be significant, especially for those operating auction or e-commerce platforms using the vulnerable plugin. Exploitation could lead to unauthorized access to user sessions, theft of sensitive information, or manipulation of auction data, undermining trust and potentially causing financial losses. The vulnerability could facilitate lateral movement within the affected web application, allowing attackers to escalate privileges or perform unauthorized transactions. Given the medium severity and requirement for authenticated access, the risk is higher in environments with many users or where user privilege management is lax. Additionally, regulatory frameworks such as GDPR impose strict requirements on protecting personal data, and a successful attack exploiting this vulnerability could result in compliance violations and fines. The reputational damage from a publicized breach could also affect customer confidence and business continuity. Organizations with public-facing WordPress sites using this plugin are particularly vulnerable to targeted phishing or social engineering attacks that could trigger the stored XSS payload.

1. Monitor the wphocus vendor channels and security advisories for an official patch or update addressing CVE-2025-68566 and apply it immediately upon release. 2. Until a patch is available, restrict plugin usage to trusted users only and limit user privileges to the minimum necessary to reduce the risk of malicious input injection. 3. Implement strict input validation and output encoding on all user-supplied data within the application to prevent script injection. 4. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context. 5. Conduct regular security audits and code reviews of customizations or integrations involving the plugin. 6. Educate users and administrators about the risks of XSS and encourage vigilance against suspicious links or inputs. 7. Use Web Application Firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting the affected plugin. 8. Maintain comprehensive logging and monitoring to detect anomalous activities that could indicate exploitation attempts. 9. Consider isolating or sandboxing the affected plugin functionality if feasible to limit potential damage. 10. Review and tighten authentication and session management controls to mitigate the impact of session hijacking.
