CVE-2025-14314 identifies a Blind SQL Injection vulnerability in Roxnor's PopupKit popup-builder-block plugin, affecting all versions up to and including 2.1.5. The vulnerability stems from improper neutralization of special elements in SQL commands, allowing attackers to inject malicious SQL code that is executed by the backend database. This injection is 'blind' because the attacker does not receive direct feedback from the database but can infer data through timing or boolean responses. The CVSS 3.1 score of 8.5 (high) reflects the vulnerability's network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), with a scope change (S:C), high confidentiality impact (C:H), low integrity impact (I:L), and no availability impact (A:N). Exploitation requires the attacker to have some level of authenticated access, but no user interaction is needed. The vulnerability allows unauthorized reading of sensitive data, potentially exposing user information, credentials, or business data. No patches or known exploits are currently documented, but the vulnerability is publicly disclosed and should be considered exploitable. PopupKit is a popular plugin used in various CMS platforms to create popups, making affected installations a target for attackers seeking to extract confidential information from databases.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive data stored in backend databases accessed via PopupKit. Attackers exploiting this flaw can extract user data, credentials, or proprietary business information without detection, leading to data breaches and regulatory non-compliance, especially under GDPR. The integrity impact is low, so data modification is less likely, but the confidentiality breach alone can cause reputational damage, financial loss, and legal penalties. The lack of availability impact means systems remain operational, potentially allowing prolonged undetected data exfiltration. Organizations in sectors such as e-commerce, media, and public services that rely on PopupKit for customer engagement are particularly vulnerable. The requirement for low privilege authenticated access means insider threats or compromised accounts can be leveraged to exploit this vulnerability. Given the widespread use of web applications in Europe and the strict data protection regulations, the impact can be severe if not addressed promptly.

1. Apply security patches from Roxnor immediately once they become available to address CVE-2025-14314. 2. Until patches are released, implement strict input validation and sanitization on all user-supplied data interacting with PopupKit to prevent SQL injection payloads. 3. Employ Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns, especially blind injection techniques. 4. Restrict database user privileges associated with PopupKit to the minimum necessary, limiting data exposure if exploited. 5. Monitor database logs and application behavior for unusual query patterns or timing anomalies indicative of blind SQL injection attempts. 6. Conduct regular security assessments and penetration testing focusing on injection vulnerabilities in PopupKit and related components. 7. Educate developers and administrators about secure coding practices and the risks of SQL injection to prevent similar vulnerabilities in future releases. 8. Consider isolating PopupKit components or using database query parameterization to reduce injection risks. 9. Review and tighten authentication mechanisms to reduce the risk of low-privilege account compromise that could facilitate exploitation.
