Detailsinfo

A vulnerability was found in logseq up to 0.10.15 and classified as critical. Affected by this issue is an unknown part of the component IPC Handler. The manipulation with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was shared by Bartłomiej Dmitruk. The advisory is available at cert.pl. This vulnerability is handled as CVE-2026-9279 since 05/22/2026. The exploitation is known to be easy. Local access is required to approach this attack. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
