{"id":"BIT-pillow-2026-54060","summary":"Pillow: `FontFile.compile()`: `Image.new()` called without `_decompression_bomb_check()`","details":"Pillow is a Python imaging library. Prior to 12.3.0, PIL/FontFile.py FontFile.compile() assembled per-glyph images into a combined bitmap with Image.new(\"1\", (xsize, ysize)) without calling Image._decompression_bomb_check(), allowing a font to trigger excessive allocation during conversion or saving.
