CVE-2026-96640

Pillow is a Python imaging library. From 5.1.0 until 13.0.0, PdfParser.linearizepagetree in src/PIL/PdfParser.py treats a PDF /Pages graph as a tree without tracking duplicate indirect references. When Image.save..., format="PDF", append=True processes an attacker-controlled existing PDF whose...

CVE-2026-96643

Pillow is a Python imaging library. From 11.0.0 until 13.0.0, Exif.load in src/PIL/Image.py repeatedly slices the remaining EXIF data while it begins with the six-byte Exif header. src/PIL/PngImagePlugin.py accepts an uncapped PNG eXIf chunk, so a file filled with repeated headers causes a new...

CVE-2026-96643

The Pillow Python imaging library (versions 11.0.0 through 13.0.0 ) is vulnerable to an inefficient algorithmic complexity issue (CWE-407 ). The root cause resides in src/PIL/Image.py, where Exif.load() repeatedly slices EXIF data starting with a six-byte header. Because src/PIL/PngImagePlugin.py...

CVE-2026-96643 Pillow: PNG eXIf chunk makes EXIF parsing run in quadratic time

Pillow is a Python imaging library. From 11.0.0 until 13.0.0, Exif.load in src/PIL/Image.py repeatedly slices the remaining EXIF data while it begins with the six-byte Exif header. src/PIL/PngImagePlugin.py accepts an uncapped PNG eXIf chunk, so a file filled with repeated headers causes a new...

CVE-2026-96642 Pillow: TarIO negative size field causes infinite CPU-spin loop

Pillow is a Python imaging library. Prior to 13.0.0, the TarIO initializer in src/PIL/TarIO.py accepts a negative octal member size and computes a backward seek that returns to the same 512-byte header. When the requested member name does not match, the parser repeatedly reads that header, consum...

CVE-2026-96642

The Pillow Python imaging library is vulnerable to an infinite CPU-spin loop in the TarIO initializer (located in src/PIL/TarIO.py) in versions prior to 13.0.0 . The root cause is the acceptance of a negative octal member size , which triggers a backward seek that returns to the same 512-byte hea...

CVE-2026-114144 toml-node: Uncontrolled resource consumption (CPU DoS) via unbounded-length integer literals in toml.parse()

toml-node is a TOML parser for Node.js and the browser. Prior to 5.0.1, toml.parse passes unbounded hexadecimal, octal, binary, and decimal digit sequences from lib/parser.js to BigInt before reduceInteger in lib/compiler.js checks whether the resulting value fits the TOML 64-bit integer range...

CVE-2026-114144

The toml-node TOML parser for Node.js and the browser is vulnerable to uncontrolled resource consumption (CPU DoS) in versions prior to 5.0.1 . The toml.parse() function passes unbounded hexadecimal, octal, binary, and decimal sequences from lib/parser.js to BigInt() before the reduceInteger() fu...

mime: golang: Golang MIME: Denial of Service via maliciously-crafted MIME header

A flaw was found in the Golang MIME Multipurpose Internet Mail Extensions package. A remote attacker could exploit this vulnerability by sending a maliciously-crafted MIME header containing many invalid encoded-words. This could lead to excessive CPU consumption, resulting in a Denial of Service...
