CVE-2025-48348 is a medium-severity vulnerability classified under CWE-266, which pertains to Incorrect Privilege Assignment. This vulnerability affects the product 'Site Offline' developed by chandrashekharsahu, specifically versions up to 1.5.7. The core issue involves incorrectly configured access control security levels, allowing users with certain privileges to potentially escalate their permissions beyond intended limits. The CVSS 3.1 base score is 4.3, indicating a medium impact primarily due to limited confidentiality impact but some integrity concerns. The vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N indicates that the vulnerability can be exploited remotely over the network (AV:N) with low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N). The scope remains unchanged (S:U), with no confidentiality or availability impact, but a partial integrity impact (I:L). This suggests that an attacker with some level of access could exploit the misconfigured privilege assignments to perform unauthorized actions that affect data integrity, such as modifying or deleting content or settings within the Site Offline application. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The vulnerability was reserved in May 2025 and published in August 2025, indicating it is a recent discovery. The lack of a patch increases the risk for organizations using this product, especially if they rely on the affected versions. The vulnerability’s nature implies that attackers need some level of authenticated access, which limits the attack surface but still poses a risk if internal users or compromised accounts exist.

For European organizations, the impact of CVE-2025-48348 depends largely on the deployment of the Site Offline product within their IT environments. Since the vulnerability allows privilege escalation through incorrect access control, it could lead to unauthorized modification of offline site content or configurations, potentially disrupting business operations or causing data integrity issues. Organizations relying on Site Offline for critical offline web content management or internal documentation may face operational disruptions or reputational damage if attackers exploit this flaw. Although the vulnerability does not directly compromise confidentiality or availability, integrity violations can lead to misinformation, unauthorized content changes, or configuration tampering, which can have downstream effects on business processes. The requirement for some level of privilege reduces the risk from external attackers but raises concerns about insider threats or compromised user accounts. European entities with strict data integrity and compliance requirements (e.g., financial institutions, healthcare providers) may find this vulnerability particularly concerning. Additionally, the absence of a patch means organizations must rely on compensating controls until an official fix is released.

1. Implement strict access control policies and regularly audit user privileges within the Site Offline application to ensure that users have only the minimum necessary permissions. 2. Monitor and log all privileged user activities to detect any unauthorized or suspicious actions promptly. 3. Restrict network access to the Site Offline management interfaces to trusted internal networks or VPNs to reduce exposure to remote attackers. 4. Employ multi-factor authentication (MFA) for all accounts with elevated privileges to reduce the risk of account compromise. 5. Until a patch is available, consider isolating the Site Offline environment or using application-layer firewalls to limit potential exploitation. 6. Educate internal users about the risks of privilege misuse and enforce strong password policies to minimize insider threat risks. 7. Stay updated with vendor announcements and apply patches immediately once they become available. 8. Conduct penetration testing focused on access control mechanisms to identify and remediate privilege escalation paths proactively.
