How to Fix CVE-2021-23472

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

bootstrap-table fixed: Latest secure release 
npm install bootstrap-table@Latest secure release
Verify Direct and Transitive Dependencies

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

npm ls bootstrap-table

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-23472, inspect your project dependencies using npm:

npm ls bootstrap-table

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

Note: The npm ls bootstrap-table 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-843: Access of Resource Using Incompatible Type ('Type Confusion'), where the product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type. In Bootstrap table, 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

This affects all versions of package bootstrap-table. A type confusion vulnerability can lead to a bypass of input sanitization when the input provided to the escapeHTML function is an array (instead of a string) even if the escape attribute is set.
