How to Fix CVE-2025-48935

To remediate this vulnerability, upgrade all affected Deno dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

deno fixed: 2.2.5 
Upgrade deno to 2.2.5
deno_node fixed: 0.134.0 
Upgrade deno_node to 0.134.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for deno

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-48935, inspect your project dependencies for Deno:

inspect dependencies for deno

Analyze the terminal output to locate any version of Deno in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.5), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Deno, 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.

Source Advisory Statement

## Summary It is possible to bypass Deno's read/write permission checks by using `ATTACH DATABASE` statement. ## PoC ```js // poc.js import { DatabaseSync } from "node:sqlite" const db = new DatabaseSync(":memory:"); db.exec("ATTACH DATABASE 'test.db' as test;"); db.exec("CREATE TABLE test.test (id INTEGER PRIMARY KEY, name TEXT);"); ``` ``` $ deno poc.js ```
