CVE-2025-53108 is a medium-severity vulnerability identified in the HomeBox application, a home inventory and organization system developed by sysadminsmedia. The vulnerability is classified under CWE-862, which refers to missing authorization. Specifically, versions of HomeBox prior to 0.20.1 lack proper authorization checks on API endpoints responsible for updating and deleting inventory item attachments. This flaw allows any authenticated user with limited privileges to perform unauthorized actions on attachments belonging to other users. Because the API does not verify ownership or permissions before allowing modifications or deletions, an attacker who has valid credentials can manipulate or delete critical inventory data that they do not own. The vulnerability does not require user interaction beyond authentication, and the attack vector is network-based (remote). The CVSS 4.0 base score is 5.3, reflecting a medium severity due to the potential for unauthorized data manipulation but limited scope and impact on confidentiality and availability. The issue has been patched in version 0.20.1, and no workarounds exist, so upgrading is mandatory to remediate the vulnerability. There are no known exploits in the wild at the time of publication, but the vulnerability's nature means it could be leveraged by insiders or attackers who have obtained valid credentials to escalate their privileges within the system and tamper with inventory data.

For European organizations using HomeBox for inventory management, this vulnerability could lead to unauthorized modification or deletion of inventory attachments, potentially resulting in data loss or corruption. This may disrupt operational workflows, cause inaccuracies in asset tracking, and lead to financial or compliance repercussions if inventory records are critical for audits or regulatory reporting. Since the flaw allows privilege escalation within the application, malicious insiders or compromised accounts could exploit it to sabotage data integrity. Although the vulnerability does not directly expose sensitive data confidentiality, the integrity and availability of inventory data are at risk. Organizations relying on HomeBox for managing physical or digital assets should be aware that this could impact business continuity and trustworthiness of their inventory records. The absence of known exploits reduces immediate risk, but the medium severity and ease of exploitation by authenticated users warrant prompt remediation.

The primary mitigation is to upgrade all HomeBox installations to version 0.20.1 or later, where the missing authorization checks have been implemented. Since no workarounds exist, patching is the only effective solution. Additionally, organizations should audit user access controls and ensure that only trusted users have authentication credentials to HomeBox, minimizing the risk of abuse by compromised accounts. Implementing strong authentication mechanisms, such as multi-factor authentication (MFA), can reduce the likelihood of unauthorized access. Monitoring and logging API usage related to inventory item attachments can help detect suspicious activity indicative of exploitation attempts. Finally, organizations should regularly review and validate inventory data integrity to quickly identify and respond to unauthorized modifications.
