CVE-2024-27307: Jsonata JSONata Expression Can Pollute The Vulnerability
CRITICALCVE-2024-27307 is a CRITICAL (CVSS 9.8) jsonata expression can pollute the vulnerability (CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')) affecting Jsonata libraries in the npm ecosystem. The issue involves jsonata expression can pollute the "object" prototype. Remediation is available by upgrading affected packages to version 1.8.7, 2.0.4.
CVE-2024-27307 at a Glance
Security Impact
CVSS: 9.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2024-27307
To remediate this vulnerability, upgrade all affected Jsonata dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install jsonata@1.8.7
npm install jsonata@2.0.4
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls jsonata
How to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2024-27307, inspect your project dependencies using npm:
npm ls jsonata
Analyze the terminal output to locate any version of Jsonata in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.8.7), your application is affected.
Note: The npm ls jsonata command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where the product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. In Jsonata, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\n\nIn JSONata versions `>= 1.4.0, < 1.8.7` and `>= 2.0.0, < 2.0.4`, a malicious expression can use the [transform operator](https://docs.jsonata.org/other-operators#-------transform) to override properties on the `Object` constructor and prototype. This may lead to denial of service, remote code execution or other unexpected behavior in applications that evaluate user-provided JSONata expressions.\n\n### Patch\n\nThis issue has been fixed in JSONata versions `>= 1.8.7` and `>= 2.0.4`. Applications that evaluate user-provided expressions should update ASAP to prevent exploitation.
