CVE-2024-49362
CWE-94Published: November 14, 2024· Updated: Jun 17, 2026
Official Description
Joplin is a free, open source note taking and to-do application. Joplin-desktop has a vulnerability that leads to remote code execution (RCE) when a user clicks on an <a> link within untrusted notes. The issue arises due to insufficient sanitization of <a> tag attributes introduced by the Mermaid. This vulnerability allows the execution of untrusted HTML content within the Electron window, which has full access to Node.js APIs, enabling arbitrary shell command execution.
Risk Analysis
Joplin-desktop is susceptible to remote code execution when a user interacts with a malicious link in an untrusted note. The flaw stems from improper sanitization of HTML attributes, allowing an attacker to escape the application sandbox and execute shell commands.
There is no known public exploit for this vulnerability, and it is not listed in the CISA KEV catalog.
Ensure the Joplin application is updated to the latest version and exercise caution when clicking links within untrusted notes.
Technical Analysis
CVE-2024-49362 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.6.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
