How to Fix CVE-2025-53604

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

web-push fixed: 0.10.4 
Upgrade web-push to 0.10.4
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 web-push

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-53604, inspect your project dependencies for Web push:

inspect dependencies for web-push

Analyze the terminal output to locate any version of Web push in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.10.4), 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-130: Improper Handling of Length Parameter Inconsistency, where the product parses a formatted message or structure, but it does not handle or incorrectly handles a length field that is inconsistent with the actual length of the associated data. In Web push, 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

The web-push crate before 0.10.4 for Rust allows a denial of service (memory consumption) in the built-in clients via a large integer in a Content-Length header. The patch was initially made available in version 0.10.3, but version 0.10.3 has since been yanked.
