Important
Before submitting a report, please read the Rules for reporting.
Only the latest version is supported with security updates.
Please report vulnerabilities through private vulnerability reporting with a proof of concept that shows the security vulnerability. Please do not contact us without this proof of concept, as we cannot fix anything without this.
For general opinions on what makes an app more or less secure, please use the forum.
Joplin is maintained by a small team, and we receive a high volume of reports that have not been verified by the person submitting them. Reviewing and reproducing an unverified finding takes us as long as a real one, so we need a few rules to keep the process workable for everyone.
-
Two active reports per person. If you have more than two open at once, we may close them all, and we may block the account.
-
Verify your report before submitting it. Confirm that the issue is still present in the latest version, and that you have actually carried out the steps your conclusion relies on. Repeatedly submitting findings that do not hold up may result in a permanent block.
Note: we're mostly linking to Chrome's documentation since our reasoning for these exclusions is the same.
No - users are allowed to link to files on their local computer. This was a feature that was implemented by popular request. There are measures in place to mitigate security risks such as a dialog to confirm whether a file with an unknown file extension should be opened.
No. This is an Electron issue and not one they will fix: electron/electron#28384
