Duplicate Advisory: External module allowlist uses a raw prefix test, so a prefix-sharing sibling package is treated as allowlisted

Type: withdrawalSource: OSV1 source record

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-7q3f-wx44-378m. This link is maintained to preserve external references. ## Original Description vm2 before 3.11.7 contains a module allowlist bypass vulnerability in isPathAllowedForModule that uses raw string prefix matching instead of boundary-anchored comparison. Attackers can reach non-allowlisted packages sharing a prefix with allowlisted modules by performing relative requires from allowlisted packages when transitive loading is disabled.
