Three SonarQube findings in webserver.py (CWE-22 path traversal, CWE-20
improper input validation):
1. get_output_name: replace blocklist check (startswith("/") or ".." in)
with os.path.realpath + os.path.commonpath containment check against
resultdir, matching the guard already used in validate_file_path().
2. getsolverlogs / deletesolverlogs: validate that the `id` path parameter
is a well-formed UUID before constructing "log_<id>" file path, closing
the taint path from HTTP input to os.path.join / open / os.unlink.
3. getsolverlogs: reject negative frombyte values before passing to
out.seek() instead of relying on OSError from the OS.

The /cuopt/cuopt managed-service endpoint accepted nvcf-asset-dir, nvcf-function-asset-ids, and nvcf-large-output-dir as HTTP headers and used them in file operations without sanitization (CWE-22). - NVCF_LARGE_OUTPUT_DIR: require absolute path and canonicalize with os.path.realpath() before passing to NVCFJobResult as resultdir. - NVCF_FUNCTION_ASSET_IDS: validate that the asset ID stays within NVCF_ASSET_DIR using os.path.realpath + os.path.commonpath containment check, matching the pattern used in validate_file_path(). Reject if asset ID is itself an absolute path or escapes the asset root. Signed-off-by: Ramakrishna Prabhu <ramakrishnap@nvidia.com>

📝 WalkthroughWalkthroughThe webserver adds UUID, offset, absolute-path, and containment validation. Supporting Python and C++ changes resolve output paths, use explicit NaN checks, adjust rotation handling, protect timer destructors, and reformat decompression code without changing its logic.

In `@python/cuopt_server/cuopt_server/webserver.py`:
- Around line 1344-1353: Update the NVCF_LARGE_OUTPUT_DIR handling in the
webserver request path to require its canonicalized path to remain within the
deployment-configured trusted output root, not merely be absolute. Resolve both
paths before validating containment, reject paths outside the root with the
existing HTTPException pattern, and preserve the canonical path passed as the
write directory.
- Around line 1363-1383: Update the result-registration flow around
NVCFJobResult.register_result so NVCF_FUNCTION_ASSET_IDS, NVCF_ASSET_DIR, and
the resolved asset path are fully validated before registering the result, or
ensure every validation exception unregisters the registered result via finally.
Preserve the existing HTTP 400 responses while preventing invalid requests from
leaving registered results behind.
