GHSA-M34P-749J-X6M6 js-toml has silent type confusion via falsy-primitive duplicate-key bypass

Summary js-toml's interpreter checks whether a key already exists in a parser-built container with if objectkey instead of if key in object. When the prior value is a falsy primitive — false, 0, 0n, 0.0, -0, or "" — the duplicate-key branch is skipped and the value is silently overwritten by a...
