CVE-2026-45058 is a critical-severity code injection vulnerability in electerm (npm), affecting versions <= 3.8.8. No fixed version is listed yet.
Impact Persistent local-pty code execution via imported bookmarks or compromised sync targets. Affects users who import bookmark JSON files or who have electerm sync configured (gist/WebDAV). The attacker can inject exec* fields or global config to cause remote code to run when a bookmark is opened or when sync is applied. Patches Not yet Workarounds Do not import unsafe data References Report / credit: https://github.com/Curly-Haired-Baboon Electerm releases: https://github.com/electerm/electerm/releases
Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.

electerm (<= 3.8.8)Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.
Kodem's Application Detection and Response identifies whether CVE-2026-45058 is reachable in your applications. Explore runtime application protection for your team.

CVE-2026-45058 is a critical-severity code injection vulnerability in electerm (npm), affecting versions <= 3.8.8. No fixed version is listed yet. Untrusted input is evaluated as executable code within the application's runtime environment.
electerm (npm) versions <= 3.8.8 is affected.
No fixed version is listed for CVE-2026-45058 yet. Monitor the advisory for updates and apply mitigations in the interim.
Whether CVE-2026-45058 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
No fixed version is listed yet. In the interim: Never evaluate untrusted input as code. Use sandboxed evaluation environments if dynamic execution is required.
