CVE-2026-22814 identifies a mass assignment vulnerability in the AdonisJS Lucid ORM, a SQL ORM built on top of Knex for the AdonisJS framework. The flaw arises from improperly controlled modification of dynamically-determined object attributes (CWE-915), allowing an attacker who can influence data passed into Lucid model assignments to overwrite internal ORM state. This can lead to unauthorized modifications of database records or bypassing application logic constraints. The vulnerability affects @adonisjs/lucid versions prior to 21.8.2 and pre-release versions 22.0.0-next.0 through 22.0.0-next.5. Exploitation requires no privileges or user interaction and can be conducted remotely, making it highly accessible to attackers. The CVSS 4.0 score of 8.2 reflects the vulnerability's high impact on integrity and the ease of exploitation. Although no public exploits are known, the potential for unauthorized data manipulation within affected applications is significant. The issue was addressed by patches in versions 21.8.2 and 22.0.0-next.6, which enforce stricter controls on attribute assignment to prevent mass assignment attacks.

For European organizations, this vulnerability poses a substantial risk to the integrity of data managed by web applications using the affected versions of AdonisJS Lucid. Attackers could manipulate database records, potentially altering critical business data, bypassing authorization logic, or corrupting application workflows. This could lead to financial losses, regulatory non-compliance (especially under GDPR if personal data integrity is compromised), and reputational damage. Since the vulnerability does not require authentication, it increases the attack surface, particularly for internet-facing applications. The impact is especially critical for sectors relying heavily on Node.js frameworks for backend services, including fintech, e-commerce, and public sector digital services. The absence of known exploits in the wild provides a window for proactive mitigation but should not reduce urgency.

European organizations should immediately audit their use of AdonisJS Lucid ORM to identify affected versions. The primary mitigation is to upgrade to version 21.8.2 or later, or 22.0.0-next.6 or later, where the vulnerability is patched. Additionally, developers should implement strict input validation and whitelist attributes allowed for mass assignment to reduce exposure. Employing runtime application self-protection (RASP) or web application firewalls (WAF) with rules targeting unusual ORM attribute modifications can provide temporary defense. Conduct thorough code reviews focusing on model assignment logic and ensure that sensitive attributes are never directly assignable from user input. Monitoring application logs for suspicious modification patterns can help detect exploitation attempts. Finally, integrate security testing into the CI/CD pipeline to catch similar issues early in development.
