The updated CVSS vector appears inconsistent with the advisory details. The write-up describes a denial-of-service (hang/memory exhaustion) with no integrity impact, but the vector now sets I:L. Also, the described attack involves passing untrusted strings (often user-controlled) into expand(), which is commonly reachable over networked interfaces; switching AV from N to L likely understates the attack vector. Please re-verify the intended CVSS v3.1 metrics (e.g., I:N and confirm correct AV) against the source (GHSA/NVD) and update the vector accordingly.
