Improper Handling of Unicode Encoding

Overview Affected versions of this package are vulnerable to Improper Handling of Unicode Encoding in the process that applies exclusion directives from MANIFEST.in due to improper Unicode normalization handling on macOS APFS or HFS+ filesystems. An attacker can cause unintended files to be...

CVE-2026-59890

setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unico...

CVE-2026-59890

Setuptools vulnerability CVE-2026-59890 affects the setuptools sdist packaging logic. Prior to 83.0.0, FileList exclusions (MANIFEST.in exclude, global-exclude, recursive-exclude, prune) were matched against on-disk file names without Unicode normalization, so an NFD filename on macOS APFS/HFS+ c...

CVE-2026-59890 setuptools: MANIFEST.in exclusion bypass in sdist via Unicode normalization collision (NFC/NFD) on macOS APFS/HFS+

setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unico...

PYSEC-2026-342 Malicious Long Unicode filenames may cause a Multiple Application-level Denial of Service

Important: Exploiting this vulnerability requires the attacker to have access to your Frigate instance, which means they could also just delete all of your recordings or perform any other action. If you have configured authentication in front of Frigate via a reverse proxy, then this vulnerabilit...

CVE-2026-49401 Deno Permission Bypass via Unicode Normalization Mismatch on macOS (APFS)

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.7.14, Deno's permission system enforces filesystem and execution restrictions by comparing the requested path against the path supplied to --deny-read, --deny-write, --deny-run, or --deny-ffi. On macOS, that comparison was done...

CVE-2026-49401

CVE-2026-49401 describes a permission bypass in Deno on macOS APFS prior to v2.7.14. The denial checks for --deny-read/--deny-write/--deny-run/--deny-ffi were performed at the raw-byte level, but APFS considers different Unicode spellings of the same name as the same file. This allowed a process ...
