CVE-2025-53452 is a security vulnerability classified under CWE-862 (Missing Authorization) affecting the Barry Event Rocket software up to version 3.3. This vulnerability arises from improperly configured access control mechanisms, allowing users with limited privileges (requiring some level of authentication but no user interaction) to perform unauthorized actions that impact the integrity of the system. The CVSS 3.1 base score of 4.3 (medium severity) reflects that the vulnerability can be exploited remotely over the network (AV:N) with low attack complexity (AC:L) and requires privileges (PR:L), but does not require user interaction (UI:N). The scope is unchanged (S:U), and the impact affects integrity (I:L) but not confidentiality or availability. Essentially, an authenticated user with limited privileges can bypass authorization checks to perform actions they should not be permitted to, potentially modifying or corrupting data or system state within Event Rocket. No known exploits are reported in the wild, and no patches have been linked yet. The vulnerability was reserved in June 2025 and published in September 2025.

For European organizations using Barry Event Rocket, this vulnerability could lead to unauthorized modifications within the application, undermining data integrity and potentially disrupting business processes that rely on accurate event management. Since the vulnerability requires some level of authentication, insider threats or compromised accounts pose a significant risk. The lack of impact on confidentiality and availability limits the scope of damage, but integrity violations can still cause operational issues, compliance violations, and loss of trust. Organizations in sectors with strict data integrity requirements, such as finance, healthcare, and critical infrastructure, could face regulatory and reputational consequences if exploited. The absence of known exploits reduces immediate risk, but the medium severity score suggests timely remediation is advisable to prevent potential misuse.

European organizations should implement strict access control reviews and audits within Barry Event Rocket deployments to identify and restrict privilege levels appropriately. Until an official patch is released, applying compensating controls such as enhanced monitoring of user activities, especially for privileged or semi-privileged accounts, is critical. Employing multi-factor authentication (MFA) can reduce the risk of credential compromise. Network segmentation and limiting Event Rocket access to trusted internal networks can reduce exposure. Organizations should also engage with Barry's vendor support channels to track patch releases and apply updates promptly once available. Additionally, conducting internal penetration testing focused on authorization bypass scenarios can help identify and mitigate similar weaknesses proactively.
