PYSEC-2026-1944 Litestar allows unbounded resource consumption (DoS vulnerability)

Summary Litestar offers multiple methods to return a parsed representation of the request body, as well as extractors that rely on those parsers to map request content to structured data types. Multiple of those parsers do not have size limits when reading the request body into memory, which allo...

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...

UBUNTU-CVE-2026-54059

Pillow is a Python imaging library. Prior to 12.3.0, PIL/PcfFontFile.py loadbitmaps read glyph dimensions from the PCF METRICS section and passed them directly to Image.frombytes without calling Image.decompressionbombcheck, allowing crafted PCF font data to cause excessive memory allocation. Thi...
