A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Official patches are available from Red Hat for affected versions of Red Hat Enterprise Linux 8 and 10. Users should apply these updates promptly as described in the Red Hat advisories (RHSA-2026:22711 and RHSA-2026:22730). For other distributions or Vim installations, upgrading to Vim version 9.2.0280 or later will mitigate this vulnerability. No additional mitigation steps are indicated by the vendor advisories.

Description

Vim (Vi IMproved) is an updated and improved version of the vi editor. Security Fix(es): * vim: zip.vim: Vim zip.vim plugin: Arbitrary file overwrite via path traversal bypass (CVE-2026-35177) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

An attacker exploiting this vulnerability could overwrite arbitrary files on the system by leveraging the path traversal flaw in the zip.vim plugin. This could lead to unauthorized modification of files, potentially impacting system integrity or user data. However, there are no known exploits in the wild at this time.

Summary

CVE-2026-35177 is a vulnerability in the zip.vim plugin of Vim (Vi IMproved) that permits arbitrary file overwrite via a path traversal bypass. This flaw allows an attacker to manipulate file paths to overwrite files outside the intended directory. The issue affects Vim versions prior to 9.2.0280. Red Hat has released security updates for their Enterprise Linux distributions (versions 8 and 10) to address this vulnerability. The vulnerability is rated as moderate severity by Red Hat Product Security. No exploits in the wild are currently known.

CWE-22Improper Limitation of a Pathname to a Restricted Directory (Path Traversal) (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
