CVE-2025-54730 is a Missing Authorization vulnerability (CWE-862) identified in the PARETO Digital Embedder for Google Reviews product, affecting versions up to 1.7.3. This vulnerability arises because certain functionality within the embedder is accessible without proper Access Control List (ACL) enforcement, allowing unauthorized users to invoke functions that should be restricted. The vulnerability does not require authentication (PR:N) or user interaction (UI:N) and can be exploited remotely over the network (AV:N). The CVSS v3.1 base score is 5.3, indicating a medium severity level. The impact primarily affects the integrity of the system, as unauthorized users can perform actions that may alter data or system behavior, but confidentiality and availability are not directly impacted. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in late July 2025 and published in mid-August 2025. The lack of proper authorization checks means attackers can bypass intended restrictions, potentially manipulating embedded Google Reviews data or related functionality, which could undermine trust in displayed reviews or cause reputational damage to organizations using this embedder.

For European organizations using the PARETO Digital Embedder for Google Reviews, this vulnerability poses a risk to the integrity of their online reputation management. Since the embedder integrates Google Reviews into websites, unauthorized manipulation could lead to falsified or altered review displays, misleading customers and damaging brand trust. This could have downstream effects on customer acquisition and retention, especially for businesses heavily reliant on online reviews. Additionally, if attackers leverage this flaw to inject malicious content or disrupt review functionality, it could degrade user experience. While confidentiality and availability impacts are minimal, the integrity compromise can have significant business consequences. Organizations in sectors such as retail, hospitality, and services, which depend on customer reviews for competitive advantage, are particularly vulnerable. The absence of authentication requirements for exploitation increases the risk of automated attacks from external threat actors.

Organizations should immediately audit their use of the PARETO Digital Embedder for Google Reviews and restrict its deployment until a vendor patch is available. In the interim, implement network-level access controls such as Web Application Firewalls (WAFs) to monitor and block suspicious requests targeting the embedder’s endpoints. Review and tighten ACL configurations on web servers hosting the embedder to ensure that only authorized users or IP ranges can access sensitive functionality. Employ runtime application self-protection (RASP) tools if available to detect and prevent unauthorized function calls. Monitor web logs for anomalous activity indicative of exploitation attempts. Engage with PARETO Digital to obtain timelines for patches and request security advisories. Once patches are released, prioritize prompt application and conduct regression testing to confirm the fix. Additionally, consider isolating the embedder component within a sandboxed environment to limit potential damage from exploitation.
