lucid: Improperly Controlled Modification of Dynamically-Determined Object Attributes
CVE-2026-22814 is a high-severity improperly controlled modification of dynamically-determined object attributes vulnerability in lucid from Adonisjs, with a CVSS 4.0 base score of 8.2 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected lucid versions: < 21.8.2; >= 22.0.0-next.0, < 22.0.0-next.6. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.54% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of lucid you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
@adonisjs/lucid is an SQL ORM for AdonisJS built on top of Knex. Prior to 21.8.2 and 22.0.0-next.6, there is a Mass Assignment vulnerability in AdonisJS Lucid which may allow a remote attacker who can influence data that is passed into Lucid model assignments to overwrite the internal ORM state. This may lead to logic bypasses and unauthorized record modification within a table or model. This affects @adonisjs/lucid through version 21.8.1 and 22.x pre-release versions prior to 22.0.0-next.6. This has been patched in @adonisjs/lucid versions 21.8.2 and 22.0.0-next.6.

The underlying weakness: Improperly Controlled Modification of Dynamically-Determined Object Attributes
The product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified.
How developers prevent this class of flaw
- If available, use features of the language or framework that allow specification of allowlists of attributes or fields that are allowed to be modified. If possible, prefer allowlists over denylists. For applications written with Ruby on Rails, use the attr_accessible (allowlist) or attr_protected (denylist) macros in each class that may be used in mass assignment.
- If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
- For any externally-influenced input, check the input against an allowlist of internal object attributes or fields that are allowed to be modified.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
