lodash

Bugs

Fixes a ReferenceError issue in lodash lodash-es lodash-amd and lodash.template when using the template and fromPairs functions from the modular builds. See https://github.com/lodash/lodash/issues/6167#issuecomment-4165269769

These defects were related to how lodash distributions are built from the main branch using https://github.com/lodash-archive/lodash-cli. When internal dependencies change inside lodash functions, equivalent updates need to be made to a mapping in the lodash-cli. (hey, it was ahead of its time once upon a time!). We know this, but we missed it in the last release. It's the kind of thing that passes in CI, but fails bc the build is not the same thing you tested.

There is no diff on main for this, but you can see the diffs for each of the npm packages on their respective branches:

• lodash: https://github.com/lodash/lodash/compare/4.18.0-npm...4.18.1-npm
• lodash-es: https://github.com/lodash/lodash/compare/4.18.0-es...4.18.1-es

v4.18.0

Security

_.unset / _.omit: Fixed prototype pollution via constructor/prototype path traversal (GHSA-f23m-r3pf-42rh, ). Previously, array-wrapped path segments and primitive roots could bypass the existing guards, allowing deletion of properties from built-in prototypes. Now and are blocked unconditionally as non-terminal path keys, matching . Calls that previously returned and deleted the property now return and leave the target untouched.
