CVE-2025-53075 is a medium severity vulnerability classified under CWE-20 (Improper Input Validation) found in Samsung Open Source rLottie version 0.2. rLottie is a library used for rendering Lottie animations, which are JSON-based vector animations widely used in UI/UX design across various platforms. The vulnerability specifically involves a Path Traversal issue caused by improper validation of input data. This flaw allows an attacker to manipulate file paths processed by the rLottie library, potentially enabling unauthorized access to files outside the intended directories. The CVSS 4.0 vector indicates that the attack requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), but requires user interaction (UI:A). The vulnerability does not impact confidentiality or integrity directly but affects availability (VA:L), suggesting that exploitation could lead to denial of service or resource disruption. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved and published in late June 2025, indicating it is a recent discovery. Given that rLottie is an open-source component integrated into Samsung products and potentially other third-party applications, the risk primarily lies in environments where rLottie v0.2 is deployed and processes untrusted input. Attackers could craft malicious Lottie animation files that exploit the path traversal to access or overwrite sensitive files, potentially disrupting application functionality or causing crashes.

For European organizations, the impact of CVE-2025-53075 depends on the extent to which Samsung products or third-party applications using rLottie v0.2 are deployed. Samsung devices, including smart TVs, mobile devices, and embedded systems, have significant market penetration in Europe. If these devices or applications process untrusted Lottie animation files (e.g., from user uploads or network sources), attackers could exploit this vulnerability to cause denial of service or disrupt services by accessing or corrupting files via path traversal. This could affect service availability, user experience, and potentially lead to operational disruptions in consumer-facing or enterprise environments using Samsung technology. Although the vulnerability does not directly lead to data breaches or privilege escalation, the availability impact could be significant in critical systems relying on Samsung devices or software components. Additionally, if rLottie is embedded in enterprise applications or digital signage solutions, exploitation could disrupt business operations. The lack of known exploits reduces immediate risk, but the medium severity and ease of exploitation with user interaction warrant timely mitigation.

Organizations should first identify all systems and applications using Samsung Open Source rLottie version 0.2. Since no official patches are currently available, mitigation should focus on minimizing exposure: 1) Restrict the processing of untrusted or user-supplied Lottie animation files, employing strict input validation and sanitization before passing data to rLottie. 2) Implement application-layer controls to detect and block suspicious file paths or malformed animation files that could trigger path traversal. 3) Employ sandboxing or containerization for applications using rLottie to limit the impact of potential exploitation. 4) Monitor logs and application behavior for anomalies indicative of exploitation attempts, such as unexpected file access or crashes. 5) Engage with Samsung or the open-source community for updates or patches and plan prompt deployment once available. 6) Educate users and administrators about the risk of opening untrusted animation files and enforce policies to avoid such scenarios. These targeted mitigations go beyond generic advice by focusing on input validation, containment, and monitoring specific to the nature of the vulnerability.
