pnpm: A tarball dependency's manifest `name` escapes node_modules → arbitrary file write/overwrite on install

pnpm is a package manager. Prior to 10.34.5 and 11.11.0, pnpm accepts a scoped path traversal in a tarball dependency's package.json manifest name because pnpm11/resolving/npm-resolver/src/pickPackage.ts rejects slash characters only for unscoped names. During pnpm install, the unvalidated name reaches raw path joins in pnpm11/installing/deps-resolver/src/resolvePeers.ts, pnpm11/installing/deps-resolver/src/index.ts, and pnpm11/deps/graph-builder/src/lockfileToDepGraph.ts, causing package extraction outside node_modules and allowing attacker-controlled files to overwrite arbitrary filesystem paths even when --ignore-scripts is used. The overwrite can replace shell startup files, Git hooks, or installed package code and lead to code execution. This issue is fixed in versions 10.34.5, and 11.11.0.
