CVE-2025-48142 is a high-severity vulnerability classified under CWE-266, which pertains to Incorrect Privilege Assignment. This vulnerability affects the software product Bookify, developed by Saad Iqbal, specifically versions up to 1.0.9. The flaw allows an attacker with some level of privileges (PR:L - Privileges Required: Low) to escalate their privileges without requiring user interaction (UI:N). The vulnerability is exploitable remotely (AV:N - Attack Vector: Network) with low attack complexity (AC:L), meaning it can be exploited easily over a network without sophisticated conditions. The scope of the vulnerability is unchanged (S:U), indicating that the impact is confined to the vulnerable component itself. The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), meaning an attacker can fully compromise the system, access sensitive data, modify or delete data, and disrupt service availability. The vulnerability arises from improper assignment of privileges within the Bookify application, allowing an attacker with limited access to gain unauthorized elevated privileges, potentially leading to full system compromise. No patches or fixes have been linked yet, and there are no known exploits in the wild as of the publication date (August 20, 2025).

For European organizations using Bookify, this vulnerability poses a significant risk. Given the high CVSS score and the ability for remote exploitation without user interaction, attackers could leverage this flaw to escalate privileges and gain unauthorized control over systems running Bookify. This could lead to data breaches involving sensitive customer or business information, disruption of services, and potential lateral movement within corporate networks. Organizations in sectors such as publishing, education, or any industry relying on Bookify for book management or related services could face operational downtime and reputational damage. The high impact on confidentiality, integrity, and availability means that exploitation could result in severe financial and regulatory consequences, especially under stringent European data protection laws like GDPR. The absence of known exploits currently provides a window for proactive mitigation before active exploitation occurs.

European organizations should immediately conduct an inventory to identify all instances of Bookify in their environments. Until a patch is released, implement strict network segmentation and access controls to limit exposure of Bookify instances to only trusted users and systems. Employ application-layer firewalls or intrusion prevention systems to monitor and block suspicious privilege escalation attempts. Review and tighten user privilege assignments within Bookify to ensure the principle of least privilege is enforced, removing unnecessary elevated rights from users. Enable comprehensive logging and monitoring to detect anomalous activities indicative of privilege escalation. Engage with the vendor or community for updates on patches or workarounds, and plan for rapid deployment of fixes once available. Additionally, consider compensating controls such as multi-factor authentication for accessing Bookify and regular security audits of the application environment.
