Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-45827 is a prototype pollution vulnerability (CWE-1321) affecting the setByPath function in the dot-diver TypeScript utility library, which provides dependency-free functions for working with object paths in dot notation. The flaw exists in all versions prior to 1.0.2 and carries a CVSS 3.1 score of 7.3.

An unauthenticated remote attacker can supply a crafted input to setByPath that pollutes Object.prototype, enabling remote code execution with impacts on confidentiality, integrity, and availability.

The official GitHub security advisory GHSA-9w5f-mw3p-pj47 and the fixing commit 98daf567 state that the issue is resolved in release 1.0.2; users are instructed to upgrade, and the advisory notes that no workarounds exist.

The associated EPSS score has remained flat at 0.1020 with no material rise after disclosure.
