- Narrow /root/.cache COPY in Dockerfile to /root/.cache/prisma{,-python}
only — drops ~660MB of uv build cache including a setuptools wheel
that surfaced as CVE-2024-6345 / CVE-2025-47273 even though it was
never on the runtime sys.path.
- DiskCache: switch to dc.JSONDisk to neutralize the pickle code path
(CVE-2025-69872, no upstream fix). Values must be JSON-serializable;
cleanup get_cache to skip the now-dead json.loads(dict) branch by
guarding on isinstance(str).
- pyproject.toml: drop diskcache pin from [caching] extra (no fixed
version exists). Stub kept so `pip install litellm[caching]` doesn't
warn; users who want disk caching install diskcache themselves.
- Bump black 24.10.0 → 26.3.1 (CVE-2026-32274) + apply 296-file mechanical
reformat. Black is dev-only (not in the runtime image), but bumping
clears the manifest-scan finding.
- Refresh ui/litellm-dashboard/package-lock.json to pick up next 16.2.4
(was 16.1.7, GHSA-q4gf-8mx6-v5v3), uuid 14.0.0, postcss 8.5.13.
- Refresh litellm-js/spend-logs/package-lock.json to pick up
hono 4.12.16 (GHSA-458j-xx4x-4375).
- uv lock: gitpython 3.1.46 → 3.1.49 (clears two High GHSAs),
langchain-text-splitters 1.1.1 → 1.1.2.
- Add tests/test_litellm/caching/test_disk_cache.py covering JSONDisk
enforcement, dict/string round-trip, TTL, increment, delete/flush.
Net delta on combined trivy + grype scans: 17 findings → 4 (all
remaining 4 are Wolfi system python-3.13 CVEs marked WONTFIX upstream
in CPython 3.14; CVE-2026-3298 is Windows-unreachable on Linux).
Existing on-disk caches written by the previous pickle-format Disk
will silently miss after upgrade — diskcache is intended to be
ephemeral so impact is recreate-on-next-write.
