CVE-2026-47900

Logseq is vulnerable to a stored cross-site scripting (XSS). A malicious plugin can include a JavaScript payload in the "name" field of its "package.json" file, which is rendered using "innerHTML" without proper sanitization, allowing the execution of arbitrary code in the privileged host context. 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.
