CVE-2026-46709: CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') in Eugeny tabby
CVE-2026-46709 is a command injection vulnerability in the Tabby terminal emulator prior to version 1.0.234. The issue arises because dropped file paths are inserted into the active shell without properly neutralizing command substitution metacharacters such as $(…) and `…`. This allows an attacker to execute arbitrary commands when the victim presses Enter. The vulnerability is fixed in version 1.0.234.
AI Analysis
Technical Summary
Tabby (formerly Terminus) versions before 1.0.234 improperly handle dropped file paths by inserting them into the active shell without sanitizing command substitution metacharacters. This incomplete neutralization, following a prior fix for control characters (CVE-2026-45038), enables command injection when a user presses Enter. The vulnerability is identified as CWE-77 and CWE-78 and has a CVSS 3.1 score of 7.8, indicating high severity. The issue is resolved in Tabby version 1.0.234.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary commands in the context of the terminal emulator when a user interacts with the dropped file path. This can lead to full confidentiality, integrity, and availability compromise of the affected system as indicated by the CVSS metrics (C:H/I:H/A:H).
Mitigation Recommendations
Upgrade Tabby to version 1.0.234 or later, where this command injection vulnerability is fixed. No other mitigation is indicated or substitutes the patch. Patch status is not explicitly stated as 'official-fix' in the metadata, but the description confirms the issue is fixed in 1.0.234.
