CVSS: 5.3EPSS: 0%CPEs: 206EXPL: 0CVE-2023-22453 – Discourse vulnerable to exposure of user post counts per topic to unauthorized users
https://notcve.org/view.php?id=CVE-2023-22453
Discourse is an option source discussion platform. Prior to version 2.8.14 on the `stable` branch and version 3.0.0.beta16 on the `beta` and `tests-passed` branches, the number of times a user posted in an arbitrary topic is exposed to unauthorized users through the `/u/username.json` endpoint. The issue is patched in version 2.8.14 and 3.0.0.beta16. There is no known workaround. • https://github.com/discourse/discourse/commit/cbcf8a064b4889a19c991641e09c399bfa1ef2ad https://github.com/discourse/discourse/security/advisories/GHSA-xx97-6494-p2rv • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 8.1EPSS: 0%CPEs: 206EXPL: 0CVE-2022-46177 – Discourse password reset link can lead to in account takeover if user changes to a new email
https://notcve.org/view.php?id=CVE-2022-46177
Discourse is an option source discussion platform. Prior to version 2.8.14 on the `stable` branch and version 3.0.0.beta16 on the `beta` and `tests-passed` branches, when a user requests for a password reset link email, then changes their primary email, the old reset email is still valid. When the old reset email is used to reset the password, the Discourse account's primary email would be re-linked to the old email. If the old email address is compromised or has transferred ownership, this leads to an account takeover. This is however mitigated by the SiteSetting `email_token_valid_hours` which is currently 48 hours. • https://github.com/discourse/discourse/commit/4bf306f0e3bf54a9ef9c5886bf1cfb85c20da570 https://github.com/discourse/discourse/commit/83944213b2b2454af80d0407f60d67641b1f0b38 https://github.com/discourse/discourse/security/advisories/GHSA-5www-jxvf-vrc3 • CWE-613: Insufficient Session Expiration •

CVSS: 3.5EPSS: 0%CPEs: 15EXPL: 0CVE-2022-46168 – Group SMTP user emails are exposed in CC email header
https://notcve.org/view.php?id=CVE-2022-46168
Discourse is an option source discussion platform. Prior to version 2.8.14 on the `stable` branch and version 2.9.0.beta15 on the `beta` and `tests-passed` branches, recipients of a group SMTP email could see the email addresses of all other users inside the group SMTP topic. Most of the time this is not an issue as they are likely already familiar with one another's email addresses. This issue is patched in versions 2.8.14 and 2.9.0.beta15. The fix is that someone sending emails out via group SMTP to non-staged users masks those emails with blind carbon copy (BCC). • https://github.com/discourse/discourse/pull/19724 https://github.com/discourse/discourse/security/advisories/GHSA-8p7g-3wm6-p3rm • CWE-359: Exposure of Private Personal Information to an Unauthorized Actor •
