CVE-2025-58813 is a medium-severity vulnerability classified under CWE-862, which pertains to Missing Authorization. This vulnerability affects the ThemeArile Consultstreet product, specifically versions up to 3.0.0. The core issue is an incorrectly configured access control mechanism that allows users with limited privileges (PR:L - privileges required: low) to perform actions or access resources beyond their authorization level without requiring any user interaction (UI:N). The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), meaning an attacker with low privileges can exploit it without needing special conditions or user involvement. The impact is limited to integrity (I:L) with no confidentiality or availability impact, indicating that unauthorized modifications to data or system state are possible, but data disclosure or service disruption is not directly affected. The scope remains unchanged (S:U), meaning the exploit affects only the vulnerable component and does not extend to other components or systems. No patches or known exploits in the wild have been reported as of the publication date (September 5, 2025). The vulnerability arises from missing or improperly enforced authorization checks within the Consultstreet application, potentially allowing attackers to bypass security controls and perform unauthorized actions such as modifying content, settings, or other sensitive operations within the application. Given that Consultstreet is a theme or plugin product likely used in web environments, this vulnerability could be leveraged to alter website content or configurations, leading to integrity issues and potential downstream impacts on business operations or user trust.

For European organizations using ThemeArile Consultstreet, this vulnerability poses a risk primarily to the integrity of their web applications or online services. Unauthorized modifications could lead to defacement, insertion of malicious content, or alteration of business-critical information, which can damage reputation and erode customer trust. While confidentiality and availability are not directly impacted, integrity breaches can have cascading effects, such as enabling further attacks or compliance violations under regulations like GDPR if personal data is indirectly affected. Organizations in sectors with high reliance on web presence—such as e-commerce, media, and public services—may face operational disruptions or legal scrutiny if unauthorized changes go undetected. The medium severity and lack of known exploits suggest that while immediate widespread exploitation is unlikely, targeted attacks against vulnerable installations remain a concern. European entities should be aware that attackers with low privileges (e.g., authenticated but limited users) could exploit this flaw without user interaction, increasing the risk of insider threats or compromised accounts being leveraged for unauthorized actions.

To mitigate CVE-2025-58813, European organizations should: 1) Conduct a thorough audit of all access control and authorization mechanisms within the Consultstreet application, ensuring that privilege checks are correctly implemented and enforced for every sensitive operation. 2) Restrict user privileges following the principle of least privilege, minimizing the number of users with elevated access rights. 3) Implement robust monitoring and logging of user actions within the application to detect unauthorized modifications promptly. 4) Apply virtual patching or compensating controls at the web application firewall (WAF) level to block suspicious requests targeting authorization bypass patterns until an official patch is available. 5) Engage with ThemeArile or trusted security vendors to obtain updates or patches as soon as they are released, and prioritize timely deployment. 6) Educate administrators and users about the risks of privilege escalation and encourage strong authentication practices to reduce the risk of compromised accounts. 7) Regularly review and update security policies related to web application management and incident response to quickly address any exploitation attempts.
