Electerm Local code through electerm's single-instance socket (CVE-2026-45353)
### Impact _Local code execution without UI interaction: any same-user process can send a JSON payload to electerm's single-instance socket/pipe, causing the app to create tabs and potentially spawn attacker-controlled local processes. Affects electerm single-instance installs on the machine._ ### Patches - https://github.com/electerm/electerm/commit/0599e67069b00e376a2e962649aaad6096e63507 ### Workarounds - Do not run unsafe command ### References - Report / credit: https://github.com/Curly-Haired-Baboon - Electerm releases: https://github.com/electerm/electerm/releases
AI Analysis
Technical Summary
This vulnerability (CVE-2026-45353) in electerm affects single-instance installations from version 3.0.6 up to but not including 3.9.0. It allows local attackers with the same user privileges to send crafted JSON payloads to electerm's single-instance socket or pipe, resulting in local code execution without requiring user interaction. The attacker can cause electerm to create new tabs and spawn processes controlled by the attacker. The vulnerability is classified under CWE-732 (Incorrect Permission Assignment for Critical Resource), CWE-94 (Improper Control of Generation of Code), and CWE-940 (Improper Use of Single-Instance). A patch has been released and is referenced in the GitHub commit 0599e67069b00e376a2e962649aaad6096e63507.
Potential Impact
An attacker with local access and the same user privileges can execute arbitrary code on the affected system without any user interaction. This can lead to unauthorized process creation and potential compromise of the local environment where electerm is installed. The impact is critical given the ability to execute code locally without UI interaction.
Mitigation Recommendations
A patch is available and should be applied by upgrading electerm to version 3.9.0 or later. Until patched, avoid running unsafe commands through electerm. Follow the official GitHub release and commit for the patch: https://github.com/electerm/electerm/commit/0599e67069b00e376a2e962649aaad6096e63507.
