GHSA-4GMW-GG2M-W46P GitPython: Unguarded git read-tree option forwarding in IndexFile.from_tree/reset/merge_tree enables arbitrary file overwrite

Summary IndexFile.fromtree, IndexFile.reset → fromtree and IndexFile.mergetree append caller-influenced treeish strings positionally to git read-tree with no unsafe-option guard, no allowunsafeoptions parameter, and no -- separator. git read-tree --index-output= writes the resulting index to an...

CVE-2026-18508 Tar: tar: --one-top-level hardlink targets not confined to top-level directory enabling arbitrary file overwrite

A flaw was found in GNU tar. When extracting an archive with the --one-top-level option, hardlink targets are not confined to the designated top-level directory and may resolve relative to the extraction working directory. A crafted archive can create hardlinks that escape the intended boundary...

CVE-2026-13723 Develar's electron-builder allows arbitrary file overwrite

A vulnerability in the zipx.Unzip extraction routine of Develar's app-builder allows an attacker to overwrite arbitrary files on macOS APFS by exploiting a Unicode Normalization Collision combined with symlink following behavior. APFS treats certain Unicode equivalent filenames as identical e.g.,...

python-pip: Path traversal via malicious entry point name in pip wheel installation allows arbitrary file overwrite

A flaw was found in pip, the package installer for Python. A remote attacker can exploit this vulnerability by tricking a victim into installing a malicious Python wheel. This wheel contains specially crafted entry-point names that use directory traversal or absolute paths. This allows pip to wri...

EUVD-2026-40068

GNU gzip contains a vulnerability in the gzexe utility related to insecure temporary file handling. When the mktemp utility is not available in the user’s PATH, gzexe falls back to constructing a temporary file path based solely on the process ID PID. This predictable filename is created without...

When sed is invoked with both -i in-place edit and --follow-symlinks, the function opennextfile performs two separate, non-atomic filesystem operations on the same path: 1. resolves symlink to its target and stores the resolved path for determining when output is written, 2. opens the original...

CVE-2026-35355

CVE-2026-35355 concerns the install utility in uutils coreutils . The vulnerability arises from a TOCTOU race during file installation: the code unlinks an existing destination file and then recreates it via a path-based operation without using the O_EXCL flag. This creates a window where a local...
