PYSEC-2026-1996 Decompression-bomb safeguards bypassed when following HTTP redirects (streaming API)

Impact urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header e.g., gzip,...

SUSE CVE-2026-54060

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.decompressionbombcheck, allowing a font to trigger excessive allocation during conversion or saving. This...

SUSE CVE-2026-55379

Pillow is a Python imaging library. Prior to 12.3.0, PIL/BdfFontFile.py bdfchar read the BBX width and height field from a BDF font file and passed attacker-controlled dimensions to Image.new without calling Image.decompressionbombcheck, bypassing Pillow's documented decompression bomb protection...

Scrapy decompression bomb vulnerability

ImpactScrapy limits allowed response sizes by default through the DOWNLOADMAXSIZE and DOWNLOADWARNSIZE settings.However, those limits were only being enforced during the download of the raw, usually-compressed response bodies, and not during decompression, making Scrapy vulnerable to decompressio...
