Vim is an open source, command line text editor. From 9.1.1784 until 9.2.0678, when the bundled zip plugin autoload/zip.vim falls back to PowerShell to browse, read, extract, update or delete entries in a zip archive, it builds the PowerShell command by inserting archive entry names that are quoted only for the shell, not for PowerShell. A crafted entry name can break out of the intended string context and cause PowerShell to execute arbitrary commands with the privileges of the user running Vim, triggered by opening, viewing or extracting the archive. This vulnerability is fixed in 9.2.0678.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1940 advisory.

    Vim is an open source, command line text editor. Prior to 9.2.0653, the tree_count_words() function in     src/spellfile.c fills in the word-count fields of a spell-file word trie by walking it iteratively with a     depth counter. The counter is bounded only by the trie structure itself; it is never checked against the     size of the fixed MAXWLEN-element stack arrays it indexes (arridx[], curi[], wordcount[]). A crafted     .spl/.sug file pair, loaded when the user invokes spell suggestion, can drive the descent arbitrarily     deep, so the function writes past the end of those arrays. This is a stack out-of-bounds write that     corrupts the call frame and crashes the editor. This vulnerability is fixed in 9.2.0653. (CVE-2026-55693)

    Vim is an open source, command line text editor. Prior to 9.2.0662, the dump_prefixes() function in     src/spell.c walks a spell-file prefix trie iteratively with a depth counter while dumping the prefixes     that apply to a word. The counter is bounded only by the trie structure itself; it is never checked     against the size of the fixed MAXWLEN-element stack arrays it indexes (prefix[], arridx[], curi[]). A     crafted .spl file, loaded when the user dumps the word list, can drive the descent arbitrarily deep, so     the function writes past the end of those arrays. This is a stack out-of-bounds write that corrupts the     call frame and crashes the editor. This vulnerability is fixed in 9.2.0662. (CVE-2026-55892)

    Vim is an open source, command line text editor. Prior to 9.2.0663, a Vimscript code injection     vulnerability exists in s:NetrwLocalRmFile() in the netrw plugin     (runtime/pack/dist/opt/netrw/autoload/netrw.vim) when deleting a local file from the browser. A filename     derived from the buffer's directory listing is interpolated into an Ex command line passed to :execute     with only the backslash character escaped, allowing a crafted filename containing a bar (|) to terminate     the intended command and execute arbitrary Vimscript, including shell commands via :call system() and :!.
    This vulnerability is fixed in 9.2.0663. (CVE-2026-55895)

    Vim is an open source, command line text editor. Prior to 9.2.0670, get_text_props() in src/textprop.c     reads a uint16 property count stored inline after a line's text and returns it as the number of 32-byte     textprop_T entries that follow. The only check is a floor that guarantees room for a single entry; the     count is never checked against the amount of data actually present. A line that declares a large count     while carrying little data causes consumers to read far past the end of the line buffer. Such a line can     be delivered through a crafted undo file, leading to a crash. This vulnerability is fixed in 9.2.0670.
    (CVE-2026-57451)

    Vim is an open source, command line text editor. From 9.1.1784 until 9.2.0678, when the bundled zip plugin     autoload/zip.vim falls back to PowerShell to browse, read, extract, update or delete entries in a zip     archive, it builds the PowerShell command by inserting archive entry names that are quoted only for the     shell, not for PowerShell. A crafted entry name can break out of the intended string context and cause     PowerShell to execute arbitrary commands with the privileges of the user running Vim, triggered by     opening, viewing or extracting the archive. This vulnerability is fixed in 9.2.0678. (CVE-2026-57453)

    Vim is an open source, command line text editor. From 9.2.0320 until 9.2.0679, a crafted undo or swap file     can store a virtual-text property whose offset and length point outside the line's property data. When Vim     restores or displays such a line it converts the offset into a pointer and reads the virtual text without     bounds checking, causing an out-of-bounds read that can crash Vim or disclose adjacent heap memory. This     vulnerability is fixed in 9.2.0679. (CVE-2026-57454)

    Vim is an open source, command line text editor. Prior to 9.2.0698, the single-byte branch of     spell_soundfold_sofo() in src/spell.c translates a word through a spell file's SOFO (sound-folding) byte     map into a caller-owned result buffer. Its copy loop advances the output index ri with no upper bound and     terminates only on the input NUL, writing one byte per input byte into the MAXWLEN-element stack buffer     the caller provides. A word longer than MAXWLEN, passed to soundfold() (or reached via sound-based spell     suggestion) while a SOFO-based spell language is active, therefore writes past the end of that buffer.
    This is a stack out-of-bounds write that corrupts the call frame and crashes the editor. This     vulnerability is fixed in 9.2.0698. (CVE-2026-57455)

    Vim is an open source, command line text editor. Prior to 9.2.0699, Vim's Python omni-completion     (runtime/autoload/python3complete.vim and the legacy pythoncomplete.vim) executes reconstructed function     and class definitions from the current buffer with exec() as part of populating the completion dictionary.
    When reconstructing that source, each scope's docstring is inserted verbatim between triple quotes with no     escaping, so a hostile buffer can break out of the triple-quoted literal and execute attacker-controlled     Python during omni-completion. This vulnerability is fixed in 9.2.0699. (CVE-2026-57456)
