CVE-2026-9279 Details
Description
Logseq exposes an IPC handler that allows the renderer process to execute shell commands. While an allowlist restricts the command name (e.g. `git`, `pandoc`, `grep`), the argument string is concatenated with the command and passed to `child_process.spawn` with the `shell: true` option, allowing shell metacharacters in the arguments to bypass the allowlist. An attacker with JavaScript execution in the renderer (e.g. via XSS or a malicious plugin) can execute arbitrary shell commands with the privileges of the Logseq process, leading to remote code execution on the host. While only version v0.10.15 was tested and confirmed as vulnerable, status of other versions is unknown since this issue was not addressed by a patch.
A vulnerability in Logseq versions through 0.10.15 allows for arbitrary shell command execution via an inter-process communication (IPC) handler. The renderer process can execute commands with the Logseq process's privileges, leading to remote code execution on the host. This issue arises because, although an allowlist restricts command names to certain utilities like git and grep, the argument strings can include shell metacharacters that bypass this restriction. An attacker with JavaScript execution capabilities in the renderer, such as through cross-site scripting (XSS) or a malicious plugin, can exploit this vulnerability.
