This could lead to additional CPU/memory consumption, but is unlikely to be a significant issue unless a zip bomb vulnerability or similar is also present.\n\n---\n\nPatch: https://github.com/aio-libs/aiohttp/commit/47fb6ae354d4fa22048f4dbe7dbf82b625f0a2f6","public_affected_ranges":["<= 3.14.1"]}],"null_published_at":"2026-11-03T10:03:26.535Z","source_updated_at":"2026-08-03T20:40:56.000Z","source_disclosed_at":"2026-08-03T20:40:55.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-03T09:58:33.950Z"}],"next_cursor":null,"snapshot_revision":"42594"}
