CVSS v3.1 |
| Mastodon is a free, open-source social network server based on ActivityPub. When an OAuth Application is destroyed, the streaming server wasn't being informed that the Access Tokens had also been destroyed, this could have posed security risks to users by allowing an application to continue listening to streaming after the application had been destroyed. Essentially this comes down to the fact that when Doorkeeper sets up the relationship between Applications and Access Tokens, it uses a `dependent: delete_all` configuration, which means the `after_commit` callback setup on `AccessTokenExtension` didn't actually fire, since `delete_all` doesn't trigger ActiveRecord callbacks. To mitigate, we need to add a `before_destroy` callback to `ApplicationExtension` which announces to streaming that all the Application's Access Tokens are being "killed". Impact should be negligible given the affected application had to be owned by the user. None the less this issue has been addressed in versions 4.2.6, 4.1.14, 4.0.14, and 3.5.18. Users are advised to upgrade. There are no known workaround for this vulnerability. |
| Mastodon is a free, open-source social network server based on ActivityPub. In versions on the 4.x branch prior to versions 4.0.10, 4.2.8, and 4.2.0-rc2, under certain conditions, attackers can abuse the translation feature to bypass the server-side HTML sanitization, allowing unescaped HTML to execute in the browser. The impact is limited thanks to Mastodon's strict Content Security Policy, blocking inline scripts, etc. However a CSP bypass or loophole could be exploited to execute malicious XSS. Furthermore, it requires user interaction, as this can only occur upon clicking the “Translate” button on a malicious post. Versions 4.0.10, 4.2.8, and 4.2.0-rc2 contain a patch for this issue. |
| Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 3.5.14, 4.0.10, 4.1.8, and 4.2.0-rc2, under certain circumstances, attackers can exploit a flaw in domain name normalization to spoof domains they do not own. Versions 3.5.14, 4.0.10, 4.1.8, and 4.2.0-rc2 contain a patch for this issue. |
| Mastodon is a free, open-source social network server based on ActivityPub. Starting in version 2.6.0 and prior to versions 3.5.9, 4.0.5, and 4.1.3, an attacker can craft a verified profile link using specific formatting to conceal arbitrary parts of the link, enabling it to appear to link to a different URL altogether. The link is visually misleading, but clicking on it will reveal the actual link. This can still be used for phishing, though, similar to IDN homograph attacks. Versions 3.5.9, 4.0.5, and 4.1.3 contain a patch for this issue. |
| app/models/user.rb in Mastodon before 3.5.0 allows a bypass of e-mail restrictions. |
| Mastodon before 3.3.2 and 3.4.x before 3.4.6 has incorrect access control because it does not compact incoming signed JSON-LD activities. (JSON-LD signing has been supported since version 1.6.0.) |
| Prototype Pollution in GitHub repository mastodon/mastodon prior to 3.5.0. |
| Mastodon before 2.6.3 mishandles timeouts of incompletely established sessions. |
