DescriptionGitHub Advisory

Vim is an open source, command line text editor. Prior to version 9.2.0276, a modeline sandbox bypass in Vim allows arbitrary OS command execution when a user opens a crafted file. The complete, guitabtooltip and printheader options are missing the P_MLE flag, allowing a modeline to be executed. Additionally, the mapset() function lacks a check_secure() call, allowing it to be abused from sandboxed expressions. Commit 9.2.0276 fixes the issue.

AnalysisAI

Arbitrary OS command execution in Vim prior to version 9.2.0276 occurs when users open maliciously crafted files containing modeline directives that bypass sandbox protections. The vulnerability exploits missing security flags on the complete, guitabtooltip, and printheader options, plus an unchecked mapset() function, enabling attackers to escape Vim's modeline sandbox and execute system commands. …

Vulnerability AssessmentAI

Exploitation The victim must open a crafted file (with malicious modeline) in Vim versions prior to 9.2.0276. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 8.2 HIGH rating reflects significant impact potential (confidentiality and integrity both HIGH, scope CHANGED indicating container escape from sandbox) but critically depends on user interaction (UI:R) and local attack vector (AV:L requiring file delivery). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a seemingly innocuous text file (configuration file, code snippet, or documentation) containing malicious modeline directives that leverage the unsanitized complete, guitabtooltip, or printheader options combined with mapset() function calls to escape Vim's sandbox. When a developer clones a malicious Git repository and opens a README or source file in Vim, or when a system administrator reviews a log file delivered via support ticket, the modeline executes immediately upon file open without additional warnings. …
Remediation Immediately upgrade to Vim version 9.2.0276 or later, which includes commit 75661a66a1db1e1f3f1245c615 that adds P_MLE flags to the vulnerable options and implements check_secure() validation in mapset(). … Detailed patch versions, workarounds, and compensating controls in full report.
