Prototype Pollution in Dexie
CVE-2022-21189 · GHSA-3xgx-r9j4-qw9w
- Affected
- npm dexie < 3.2.2; >= 4.0.0-alpha.1, <= 4.0.0-alpha.2
- Fixed in
- 3.2.24.0.0-alpha.3· Vendor fix available
- Issue
- Dexie is a minimalistic wrapper for IndexedDB. The package dexie before 3.2.2, from 4.0.0-alpha.1 and before 4.0.0-alpha.3 are vulnerable to Prototype Pollution in the Dexie.setByKeyPath(obj, keyPath, value) function which does not properly check the keys being set (like proto or constructor). This can allow an attacker to add/modify properties of the Object.prototype leading to prototype pollution vulnerability. Note: This vulnerability can occur in multiple ways, for example when modifying a collection with untrusted user input.
Recommended action: Upgrade to 4.0.0-alpha.3 (pre-release) or 3.2.2 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
