CVE-2026-45037: CWE-184: Incomplete List of Disallowed Inputs in Eugeny tabby
CVE-2026-45037 is a high-severity vulnerability in Tabby terminal emulator versions prior to 1. 0. 232. The issue arises because Tabby's terminal linkifier does not validate the protocol scheme of URIs before passing them to the operating system's protocol handler. This allows a malicious SSH or Telnet server to send crafted terminal output containing dangerous protocol URIs, which Tabby renders as clickable links. Clicking these links can trigger arbitrary OS protocol handlers, potentially leading to limited confidentiality, integrity, and availability impacts. The vulnerability is fixed in version 1. 0. 232.
AI Analysis
Technical Summary
Tabby (formerly Terminus) terminal emulator versions before 1.0.232 contain an incomplete validation of disallowed inputs in its terminal linkifier component. Specifically, it passes detected URIs directly to the OS protocol handler without validating the protocol scheme. This flaw allows malicious servers to send crafted terminal output with dangerous protocol URIs that become clickable links, triggering arbitrary OS protocol handlers when clicked. The vulnerability is identified as CWE-184 (Incomplete List of Disallowed Inputs) and CWE-601 (Open Redirect), with a CVSS 3.1 score of 7.1 (high severity). The issue is resolved in Tabby version 1.0.232.
Potential Impact
Exploitation of this vulnerability can lead to an attacker causing the victim's system to launch arbitrary OS protocol handlers via malicious clickable links in the terminal output. This may result in limited confidentiality, integrity, and availability impacts as indicated by the CVSS vector. However, there are no known exploits in the wild at this time.
Mitigation Recommendations
A fix for this vulnerability is available in Tabby version 1.0.232. Users should upgrade to version 1.0.232 or later to remediate this issue. No other official remediation or temporary fixes are documented. Patch status is not explicitly stated in the vendor advisory, but the description confirms the vulnerability is fixed in 1.0.232.
