## fix(security): bump tar to 7.5.16 across lockfiles (PAX file
smuggling)
Resolves [#1472 1474 1476 1479 1481 1483 1485 1487 1489 1491 1493 1496
1498 1505](https://github.com/twentyhq/twenty/security/dependabot/1472
1474 1476 1479 1481 1483 1485 1487 1489 1491 1493 1496 1498 1505).
### What
`tar` (`node-tar`) `<= 7.5.15` applies a PAX size override to
intermediary GNU long-name/long-link headers, causing a tar-parser
interpretation differential (file smuggling). Patched in `7.5.16`.
### Why these alerts
The advisory is scanned across many independent Yarn projects, so it
surfaced as one alert per lockfile: the root `yarn.lock` plus 13
`packages/twenty-apps/**` lockfiles (each pulls `tar` transitively).
### How
- Refreshed `tar` to `7.5.16` in the root and all 13 app lockfiles —
they hold `tar` via `^7.5.x` ranges that already permit it, so this is
an in-range lockfile refresh (no override) via `yarn up -R tar`.
- The root additionally had `tar@7.5.15` exact-pinned by
`@mintlify/previewing`, which has **no upstream fix** (latest `4.0.1163`
still pins `7.5.15`). Added a scoped resolution
`@mintlify/previewing/tar -> ^7.5.16`, **extending the existing scoped
tar resolutions** already used for `@electron/rebuild` and
`@electron/node-gyp`.
### Not included
`seed-dependencies/yarn.lock` (alert #1500) is intentionally excluded:
that lockfile and its checksum constants are already modified by the
open form-data PR, so its `tar` bump will follow separately to avoid a
conflict.
### Verification
- No `tar <= 7.5.15` remains across the root or any app lockfile.
- `yarn install --immutable` passes.
