seroval@0.1.0 exports only serialize() and does not include any deserialization code path. The vulnerable deserialize() function—whose implementation passes attacker-controlled input to indirect evaluation via (0, eval)(source) (see src/index.ts:90)—is first introduced in 0.2.0.

Because 0.1.0 contains no eval-backed deserializer, it provides no sink through which a malicious payload can be executed.

Accordingly, the correct introduced version is 0.2.0, which is the first release that actually contains the vulnerable sink. This aligns the affected range with the first version in which the bug is reachable.
