Bump urllib3 and gdown to resolve open Dependabot alerts#396
Merged
Conversation
Both packages were pinned below their patched versions, so Dependabot couldn't auto-resolve: - urllib3<2.0 blocked CVE-2025-50181's fix (2.5.0) - gdown<5 blocked CVE-2026-40491's fix (5.2.2) urllib3 is only a transitive dependency (not imported directly). gdown is used in exactly one place (exampledata.get_classifier_database_from_pysilcam_blob via download_folder), not the vulnerable extractall() function, and download_folder's signature is unchanged through 6.1.0. Verified by running the full test suite and pipeline-holo.ipynb with urllib3 2.7.0 and gdown 6.1.0 actually installed.

Summary
Resolves the two currently-open Dependabot alerts:
gdown— path traversal ingdown.extractall()(CVE-2026-40491), fixed in 5.2.2. Thegdown<5ceiling blocked the fix.urllib3— redirects not disabled when retries are disabled onPoolManagerinit (CVE-2025-50181), fixed in 2.5.0. Theurllib3<2.0ceiling blocked the fix.Neither ceiling had a documented reason (no comment, no explanatory commit message); the
urllib3<2.0pin traces back to 2023 and looks like leftover macOS/SSL compatibility cruft.Risk assessment:
urllib3isn't imported directly anywhere inpyopia— transitive dependency only.gdownis used in exactly one place (pyopia/exampledata.py, viagdown.download_folder), not the vulnerableextractall()function.download_folder's call signature is unchanged through the latest 6.1.0.Test plan
