CVE-2025-60095 is a vulnerability classified under CWE-201, which involves the insertion of sensitive information into sent data within the Benjamin Intal Stackable product. This vulnerability allows an attacker with at least low-level privileges (PR:L) and network access (AV:N) to retrieve embedded sensitive data that should not be exposed. The vulnerability affects Stackable versions up to 3.18.1, with no specific lower bound version identified. The CVSS 3.1 base score is 4.3, indicating a medium severity level. The attack vector is network-based, requiring no user interaction (UI:N), and the scope remains unchanged (S:U). The impact is limited to confidentiality (C:L), with no impact on integrity or availability. Essentially, an attacker who can access the network and has some privileges can extract sensitive information embedded in data sent by the Stackable product, potentially leading to information leakage. There are no known exploits in the wild, and no patches have been linked yet, suggesting that mitigation may currently rely on workarounds or vendor updates pending release. The vulnerability arises from improper handling or insertion of sensitive data into transmitted data streams, which could be intercepted or accessed by unauthorized parties with network access and some privileges.

For European organizations using Benjamin Intal Stackable, this vulnerability poses a risk of sensitive data leakage, which can compromise confidentiality of internal or customer information. Although the impact is limited to confidentiality and does not affect integrity or availability, the exposure of sensitive data can lead to compliance violations under regulations such as GDPR, potentially resulting in legal penalties and reputational damage. Organizations in sectors handling sensitive personal data, such as finance, healthcare, and government, are particularly at risk. Since exploitation requires some level of privileges and network access, insider threats or attackers who have gained initial footholds could leverage this vulnerability to escalate data exposure. The lack of known exploits suggests that immediate widespread attacks are unlikely, but the medium severity rating and the nature of the vulnerability warrant proactive measures to prevent data leakage. The absence of patches means organizations must be vigilant in monitoring and controlling access to affected systems and data flows.

1. Restrict network access to Benjamin Intal Stackable instances by implementing strict network segmentation and firewall rules to limit exposure to trusted users and systems only. 2. Enforce the principle of least privilege rigorously to ensure that users and processes have only the minimum necessary permissions, reducing the risk that an attacker can gain the required privileges to exploit this vulnerability. 3. Monitor network traffic for unusual data transmissions that may indicate leakage of sensitive information, employing data loss prevention (DLP) tools tailored to detect sensitive data patterns. 4. Engage with Benjamin Intal or authorized vendors to obtain patches or updates as soon as they become available and prioritize their deployment. 5. Conduct regular security audits and code reviews focusing on data handling and transmission mechanisms within Stackable to identify and remediate any insecure data insertion practices. 6. Implement encryption for data in transit to reduce the risk that intercepted data reveals sensitive information, assuming Stackable supports or can be configured for encrypted communications. 7. Prepare incident response plans that include scenarios involving sensitive data leakage to ensure rapid containment and remediation if exploitation occurs.
