Discourse Patreon enables syncronization between Discourse Groups and Patreon rewards. On sites with Patreon login enabled, an improper authentication vulnerability could be used to take control of a victim's forum account. This vulnerability is patched in commit number 846d012151514b35ce42a1636c7d70f6dcee879e of the discourse-patreon plugin. Out of an abundance of caution, any Discourse accounts which have logged in with an unverified-email Patreon account will be logged out and asked to verify their email address on their next login. As a workaround, disable the patreon integration and log out all users with associated Patreon accounts.

Discourse is an open source discussion platform. Versions prior to 2.7.13 in `stable`, 2.8.0.beta11 in `beta`, and 2.8.0.beta11 in `tests-passed` allow some users to log in to a community before they should be able to do so. A user invited via email to a forum with `must_approve_users` enabled is going to be automatically logged in, bypassing the check that does not allow unapproved users to sign in. They will be able to do everything an approved user can do. If they logout, they cannot log back in. This issue is patched in the `stable` version 2.7.13, `beta` version 2.8.0.beta11, and `tests-passed` version 2.8.0.beta11. One may disable invites as a workaround. Administrators can increase `min_trust_level_to_allow_invite` to reduce the attack surface to more trusted users.

Discourse before 2.3.0 and 2.4.x before 2.4.0.beta3 lacks a confirmation screen when logging in via an email link.

An issue was discovered in Zeroheight (SaaS) prior to 2025-06-13. A legacy user creation API pathway allowed accounts to be created without completing the intended email verification step. While unverified accounts could not access product functionality, the behavior bypassed intended verification controls and allowed unintended account creation. This could have enabled spam/fake account creation or resource usage impact. No data exposure or unauthorized access to existing accounts was reported.

A vulnerability was found in SourceCodester Online Pizza Ordering System 1.0. It has been classified as critical.

Broken Authentication vulnerability in JumpDEMAND Inc. ActiveDEMAND plugin <= 0.2.27 at WordPress allows unauthenticated post update/create/delete.

This vulnerability in the Snyk Kubernetes Monitor can result in irrelevant data being posted to a Snyk Organization, which could in turn obfuscate other, relevant, security issues. It does not expose the user of the integration to any direct security risk and no user data can be leaked. To exploit the vulnerability the attacker does not need to be authenticated to Snyk but does need to know the target's Integration ID (which may or may not be the same as the Organization ID, although this is an unpredictable UUID in either case).
