Two attacker-controlled strings were being joined to library_dir with no
resolve + containment check in the project ZIP import endpoint:
- linked_folders[*].name from the request's project.json
- per-entry zf.namelist() paths from the ZIP itself
An absolute path in either field collapsed the join (Path("/lib") / "/etc"
becomes Path("/etc") because pathlib discards the left side when the right
is absolute) and the next write_bytes landed wherever the attacker chose.
Adjacent finding from the routes audit: GET /archives/{id}/photos/{filename}
had NO validation on filename and FileResponse-served arbitrary paths -
the DELETE counterpart at least gated on the photos membership check.
Adjacent finding from the services audit: ArchiveService.attach_timelapse
wrote archive_dir / filename where filename ultimately came from a printer's
FTP listing (compromised-printer threat model) or the /timelapse/select
query param. A malicious printer that exposes a directory entry with ..
segments could write the timelapse outside the archive directory.
New backend/app/utils/safe_path.py::safe_join_under(parent, *parts) is the
single source of truth: rejects empty / null-byte / absolute parts up-front,
joins under parent, resolves both sides, asserts is_relative_to. Returns the
resolved canonical path on success, raises HTTPException(400) on escape, or
PathTraversalError when http=False (for service-layer callers that need to
match a non-HTTP return contract).
Wired into the import vectors, both archive photo handlers, and the
attach_timelapse service. The full audit sweep inspected every Path/Name
join in backend/app/api/routes/ AND backend/app/services/ - 25 route-layer
sites + 8 service-layer sites confirmed safe and tagged with
# SEC-PATH-OK: <reason> so future audits trust the inline guard at a glance.
Fifth CI backstop test_route_path_arithmetic_is_safe_joined_or_marked
AST-walks both layers and fails the build on any <dir-like>/<bare variable>
join that doesn't either route through safe_join_under or carry the marker.
The services layer is in scope because it receives values verbatim from the
routes AND from external sources Bambuddy has no control over (the printer
FTP-listing case above).
SECURITY.md gets a fifth rule + a fifth row in the CI test mapping table;
the rule now names the printer FTP-listing case explicitly so future
services-layer audits set the right expectation.

fix(library): suppress warning storm when bulk-uploading ZIPs of empty/stub STL files
Uploading a ZIP of stub or empty STL files (e.g. the 24-byte
"solid test\nendsolid test" shape) produced one WARNING per file in
stl_thumbnail.py::generate_stl_thumbnail. The warnings were technically
correct - trimesh returns a valid Mesh with zero vertices, the safeguard
matches, and the function returns None so the library entry is still
created without a thumbnail - but the volume turned a successful upload
into thousands of WARNING lines in the journal.
Two changes:
1. The per-file "Failed to load STL or empty mesh" message in
stl_thumbnail.py is now logger.debug instead of logger.warning. It's
a per-file content observation, not an actionable error; the caller
already handles None correctly. The branch now catches the rare
"large enough but trimesh still can't parse it" case, visible in
debug logs without spamming production.
2. New module constant MIN_USABLE_STL_BYTES = 200 (smallest binary STL
with one triangle is 134B, smallest ASCII ~150B; 200 is a safe floor
below any real STL). The three thumbnail call sites in library.py
(extract_zip_file, single-file upload, _backfill_external_stl_thumbnails)
pre-skip files below this size before calling generate_stl_thumbnail.
Stubs never enter the trimesh pipeline at all.
Behavior is unchanged for real STLs: any file >=200 bytes runs through
the existing pipeline, MAX_VERTICES still triggers simplification at
100k vertices for the 256x256 thumbnail render, large files still get
thumbnails.
------------
fix(stl-thumbnail): silence matplotlib first-import noise (writable cache + font_manager log level)
On first STL upload, three matplotlib-internal log lines surfaced:
WARNING [matplotlib] /opt/claude/.config/matplotlib is not a writable directory
INFO [matplotlib.font_manager] Failed to extract font properties from NotoColorEmoji.ttf
INFO [matplotlib.font_manager] generated new fontManager
The writable-dir warning fired because Bambuddy's $HOME isn't writable for
matplotlib's default config path; matplotlib fell back to /tmp/matplotlib-XXX
which lost the font cache on every host reboot, so font_manager rebuilt it
each cold start - producing another batch of INFO lines.
Fix is two small additions in stl_thumbnail.py before the matplotlib import:
1. New _configure_matplotlib_cache() sets MPLCONFIGDIR to
settings.base_dir/.cache/matplotlib (mkdir if missing) so the cache
persists across container restarts and the writable-dir warning never
fires. Respects an externally-set MPLCONFIGDIR so operators who chose
their own path aren't overridden. Best-effort with a debug fallback if
settings can't be imported or the mkdir fails.
2. logging.getLogger("matplotlib.font_manager").setLevel(WARNING) at module
import demotes the per-font INFO scan that fires when font_manager
builds its cache cold. Real font warnings (>= WARNING) still surface.
3 new tests: font_manager logger at WARNING after module import;
_configure_matplotlib_cache creates the directory under base_dir and sets
MPLCONFIGDIR; an externally-set MPLCONFIGDIR is preserved verbatim.
5516 backend tests green, frontend gates clean.
@smandon flagged the 40×40 cover thumbnail as too small to recognise
the print and asked for a click-to-enlarge full preview. Enlarging
the thumbnail itself would shift the card grid layout, so keep the
small thumbnail and show a 384×384 hover popover with the full image
in ``object-contain`` rendering (so tall MakerWorld photos aren't
cropped to a square).
Why a portal: ProjectCard carries ``overflow-hidden`` (rounded
corners + color accent bar), so any in-tree popover gets clipped the
moment it extends past the card. Rendering via
``createPortal(..., document.body)`` escapes every ancestor clipping
context, and ``position: fixed`` with measurements from
``getBoundingClientRect()`` keeps the popover pinned next to the
thumbnail regardless of grid position. ``pointer-events-none`` on the
popover so it can't intercept hover and create a flicker loop;
``z-[100]`` so it stacks above sibling cards.
Edge handling: if the thumbnail is near the viewport's right edge the
popover flips to the LEFT side of the thumbnail; vertical position is
clamped so the popover never overflows the window top or bottom. The
thumbnail's own ``onClick`` is ``stopPropagation``'d so hovering the
popover area never accidentally triggers the parent card's
"open project" navigation.
Tests: 2 new ``ProjectsPage.test.tsx`` cases — mouseenter mounts the
popover at document.body level (not nested in the card subtree, which
would re-introduce the clipping bug, and the assertion catches that);
mouseleave unmounts it; the popover img points at the same
cover-image URL as the small thumbnail with ``object-contain``; cards
without a cover_image_filename never mount the portal-rendering
component.
Two new project fields: a free-text URL rendered as a one-click
external-link button beside the project name on every card (opens in a
new tab, click is e.stopPropagation()-guarded so it doesn't enter the
project), and a cover photo that replaces the status-icon box with a
square thumbnail.
URL is plumbed through ProjectCreate/Update/Response/ListResponse,
including from-template + create-template flows so it inherits between
a project and its template. Cover photo is not inherited because the
file would be shared on disk between source and copy.
Schema validator rejects anything other than http:// or https://
prefixes -- <a href> rendering would otherwise execute javascript:
/ data: / file: URLs even with React's default escaping. PATCH uses
model_fields_set for the URL field so users can clear it by sending
{"url": null}.
Cover image storage: Project.cover_image_filename references a file
Cover image storage: Project.cover_image_filename references a file
inside the existing archives/projects/{id}/attachments/ dir, but it's
tracked separately from the attachments JSON list so swap/delete on
the cover doesn't perturb the user's other attachments. Three routes
(POST/GET/DELETE /projects/{id}/cover-image) accept only .jpg/.jpeg/
.png/.gif/.webp (no SVG -- SVG can carry script payloads), replace in
place (prior file deleted before the new one lands so repeat uploads
can't accumulate orphans), and self-heal when a DB reference points at
a vanished disk file by clearing the column and 404'ing.
GET cover-image is gated by RequireCameraStreamTokenIfAuthEnabled
(accepts ?token=... query string) -- not the bearer-token gate -- so
<img src> requests work in both auth-on and auth-off configurations.
The frontend wraps getProjectCoverImageUrl with withStreamToken(),
matching the existing pattern from getArchiveThumbnail.
Permissions: PROJECTS_UPDATE for upload/delete/PATCH, PROJECTS_READ

idempotent ALTER TABLE projects ADD COLUMN. Localised across all 8

Files added to a project from the archive (status="archived") were
incorrectly counted in completed_prints and parts_progress stats.
Only status="completed" (actually printed) now counts toward completion.

- Import from ZIP (creates folders and extracts files) or JSON
- New /api/v1/projects/import/file endpoint for file uploads
- Frontend buttons on Projects page and Project Detail page
- BOM items are now fully editable (not just checkbox toggle)
