Vim: Eight Vulnerabilities Disclosed Together, Patched in 9.2.0699

Eight vulnerabilities affecting the Vim text editor were disclosed on June 26, 2026, impacting spell checking, text handling, and file operations.

Key findings

  • Eight vulnerabilities disclosed for Vim on June 26, 2026, patched in version 9.2.0699.
  • Vulnerabilities affect spell checking, text properties, Python completion, file encryption, and archive handling.
  • Issues include unbounded counters, improper validation, integer underflows, and command injection flaws.
  • Users are urged to update to Vim version 9.2.0699 or later for security.

On June 26, 2026, a batch of eight vulnerabilities was disclosed for the Vim text editor. These vulnerabilities, primarily affecting spell-checking and text processing functionalities, were all patched in version 9.2.0699. The disclosures highlight potential risks in how Vim handles crafted input files and internal data structures.

Several of the vulnerabilities stem from improper handling of data within Vim's spell-checking mechanisms. CVE-2026-55693 and CVE-2026-55892 involve issues with tree_count_words() and dump_prefixes() functions, respectively, where depth counters are not adequately checked against the size of the trie structure, potentially leading to out-of-bounds reads. Similarly, CVE-2026-57455 describes a flaw in spell_soundfold_sofo() where a copy loop lacks an upper bound, risking buffer overflows.

Other vulnerabilities target different aspects of Vim's text processing and file handling. CVE-2026-57456 points to a vulnerability in Vim's Python omni-completion, where reconstructed function and class definitions are executed using exec(), potentially allowing for code execution if malicious definitions are processed. CVE-2026-57451 involves an issue in get_text_props() where an inline property count is not sufficiently validated, leading to incorrect memory reads. CVE-2026-57454 describes a vulnerability where crafted undo or swap files can store virtual-text properties with invalid offsets and lengths, causing out-of-bounds reads when restoring or displaying lines.

Additionally, two vulnerabilities relate to file encryption and archive handling. CVE-2026-57452 arises from an unsigned length calculation underflow when opening short encrypted files using specific VimCrypt methods, leading to potential issues with libsodium secretstream headers. CVE-2026-57453 details a flaw in the bundled zip plugin's fallback to PowerShell, where archive entry names are not sufficiently quoted, potentially leading to command injection when performing operations on zip archives.

All eight vulnerabilities were addressed in Vim version 9.2.0699. Users are strongly advised to update to this version or later to mitigate these security risks. The coordinated disclosure of these issues underscores the importance of keeping the Vim editor updated to protect against potential exploits targeting its various features.

The timely patching of these eight vulnerabilities in a single release highlights the vendor's responsiveness to security concerns. Users of Vim should prioritize updating their installations to version 9.2.0699 or newer to ensure they are protected against these discovered weaknesses. The range of affected components, from Python completion to spell checking and file handling, emphasizes the need for vigilance in maintaining software security.

The vulnerabilities disclosed include:

  • CVE-2026-57456: Python omni-completion vulnerability using exec().
  • CVE-2026-57451: get_text_props() improper validation of inline property count.
  • CVE-2026-55693: tree_count_words() depth counter unbounded in spell files.
  • CVE-2026-57455: spell_soundfold_sofo() copy loop unbounded.
  • CVE-2026-55892: dump_prefixes() depth counter unbounded in spell files.
  • CVE-2026-57452: Unsigned length underflow in VimCrypt file handling.
  • CVE-2026-57454: Crafted undo/swap files with out-of-bounds virtual-text properties.
  • CVE-2026-57453: Zip plugin's PowerShell fallback command injection vulnerability.

All identified vulnerabilities were fixed in Vim version 9.2.0699. This release addresses issues across multiple components, including spell checking, text properties, Python completion, file encryption, and archive handling.

Users should update to Vim version 9.2.0699 or a later version to ensure their installations are protected against these vulnerabilities. The breadth of the issues patched in this single update highlights the importance of regular updates for the Vim editor.
