Immutable.js `List` 32-bit trie overflow → unrecoverable DoS
Author: AllThingsSmittyCreated Jul 24, 2026Updated Aug 11, 2026
I received a Dependabot security alert for a repo that's using browser-sync 3.0.4 concerning Immutable being vulnerable to Immutable.js List 32-bit trie overflow:
Dependabot cannot update immutable to a non-vulnerable version The latest possible version that can be installed is
3.8.3because of the following conflicting dependencies:[email protected] requires immutable@^3 [email protected] requires immutable@^3 via [email protected] A patched version exists for immutable, but the available update path still resolves it to 3.8.3The earliest fixed version is
4.3.9.
Similar to issue #2111
Is there a plan for a browser-sync update to handle this?
