CVE-2026-46483

Vim is an open source, command line text editor. Prior to 9.2.0479, a command injection vulnerability exists in tar#Vimuntar() in runtime/autoload/tar.vim when decompressing .tgz archives on Unix-like systems. The function builds :!gunzip and :!gzip -d commands using shellescape(tartail) without the {special} flag, allowing a crafted archive filename to trigger Vim cmdline-special expansion and execute shell commands in the user's context. This vulnerability is fixed in 9.2.0479.

Vim is an advanced text editor that seeks to provide the power of the de-facto Unix editor 'Vi', with a more complete feature set. Vim is a highly configurable text editor built to enable efficient text editing. It is an improved version of the vi editor distributed with most UNIX systems.

Security Fix(es):

Vim is an open source, command line text editor. Prior to version 9.2.0383, an OS command injection vulnerability exists in the netrw standard plugin bundled with Vim. By inducing a user to open a crafted URL (e.g., using the sftp:// or file:// protocol handlers), an attacker can execute arbitrary shell commands with the privileges of the Vim process. This issue has been patched in version 9.2.0383.(CVE-2026-42307)

Vim is an open source, command line text editor. Prior to version 9.2.0435, an OS command injection vulnerability exists in Vim's :find command-line completion. When the path option contains backtick-enclosed shell commands, those commands are executed during file name completion. Because the path option lacks the P_SECURE flag, it can be set from a modeline, allowing an attacker who controls the contents of a file to execute arbitrary shell commands when the user opens that file in Vim and triggers :find completion. This issue has been patched in version 9.2.0435.(CVE-2026-44656)

Vim is an open source, command line text editor. Prior to version 9.2.0450, a heap buffer overflow exists in read_compound() in src/spellfile.c when loading a crafted spell file (.spl) with UTF-8 encoding active. An attacker-controlled length field in the spell file's compound section overflows a 32-bit signed integer multiplication, causing a small buffer to be allocated for a write loop that runs many iterations, overflowing the heap. Because the 'spelllang' option can be set from a modeline, a text file modeline can trigger spell file loading if a malicious .spl file has been planted on the runtimepath. This issue has been patched in version 9.2.0450.(CVE-2026-45130)

• CVE-2026-46483: fix command injection in the tar plugin's tar#Vimuntar() function by using the correct shellescape(tartail, 1) form so that a crafted .tgz filename cannot trigger cmdline-special expansion in the :! command

  • CVE-2026-46483

• SECURITY UPDATE: command injection in the tar plugin: tar#Vimuntar() escaped the tarball name with shellescape() without the special argument before running gunzip/gzip through :!, so characters that Vim expands in a :! command line (such as % and #) survived in the name and let a crafted archive name run arbitrary shell commands.
  • debian/patches/CVE-2026-46483.patch: use the shellescape(name, 1) form for both :! invocations in runtime/autoload/tar.vim; matches upstream patch 9.2.0479.
  • CVE-2026-46483
• SECURITY UPDATE: code injection via netrw directory history: s:NetrwBookHistSave() serialised each history entry into ~/.vim/.netrwhist by wrapping the value in single quotes with string concatenation, so a directory name containing a single quote closed the literal and injected Vimscript that ran when the history file was sourced on the next netrw start.
  • debian/patches/CVE-2026-47162.patch: encode the value with string() in runtime/autoload/netrw.vim; matches upstream patch 9.2.0495.
  • CVE-2026-47162
• SECURITY UPDATE: code execution through Python omni-completion: pythoncomplete and python3complete rebuilt the buffer's Python code and passed it to exec(), including the import and from statements harvested from the buffer, so invoking omni-completion in a hostile Python file executed arbitrary module-level code.
  • debian/patches/CVE-2026-52858.patch: skip import/from statements unless g:pythoncomplete_allow_import is set, in both runtime/autoload/pythoncomplete.vim and python3complete.vim; matches upstream patches 9.2.0561 and 9.2.0568, the latter being required for the opt-in to take effect at all.
  • CVE-2026-52858
• SECURITY UPDATE: out-of-bounds access when a terminal buffer is snapshotted: the per-cell loop in move_terminal_to_buffer() walked cell.chars[] with no upper bound, and libvterm leaves that array unterminated when a cell uses all VTERM_MAX_CHARS_PER_CELL slots (a base character plus five combining marks), so it read past the array and appended the out-of-bounds values to a buffer sized for far fewer bytes.
  • debian/patches/CVE-2026-52859.patch: bound the loop with i < VTERM_MAX_CHARS_PER_CELL and size the buffer for six 6-byte characters, in src/terminal.c; matches upstream patch 9.2.0565 together with its prerequisite 8.1.0611, without which the bounded loop would still overrun the MB_MAXBYTES-sized buffer.
  • CVE-2026-52859
• SECURITY UPDATE: code execution through Python omni-completion definition headers: Scope.get_code() reproduced def and class headers verbatim in the source handed to exec(), and Python evaluates parameter default values, annotations and base-class expressions at definition time, so crafted headers ran arbitrary code during completion even with imports disabled.
  • debian/patches/CVE-2026-52860.patch: strip default values and annotations from parameters and accept only dotted names as base classes, in both runtime/autoload/pythoncomplete.vim and python3complete.vim; matches upstream patch 9.2.0597.
  • CVE-2026-52860
• SECURITY UPDATE: out-of-bounds write reading a crafted spell file: tree_count_words() and sug_filltree() descended the word trie without bounding the depth, so a deeply nested trie wrote past the ends of their MAXWLEN-sized arridx[], curi[] and wordcount[] arrays.
  • debian/patches/CVE-2026-55693.patch: only descend while depth < MAXWLEN - 1 in both trie walkers, in src/spellfile.c; matches upstream patch 9.2.0653.
