CVSS: 4.3EPSS: 0%CPEs: 2EXPL: 0CVE-2024-21630 – Zulip non-admins can invite new users to streams they would not otherwise be able to add existing users to
https://notcve.org/view.php?id=CVE-2024-21630
25 Jan 2024 — Zulip is an open-source team collaboration tool. A vulnerability in version 8.0 is similar to CVE-2023-32677, but applies to multi-use invitations, not single-use invitation links as in the prior CVE. Specifically, it applies when the installation has configured non-admins to be able to invite users and create multi-use invitations, and has also configured only admins to be able to invite users to streams. As in CVE-2023-32677, this does not let users invite new users to arbitrary streams, only to streams t... • https://github.com/zulip/zulip/commit/0df7bd71f32f3b772e2646c6ab0d60c9b610addf • CWE-862: Missing Authorization •
CVSS: 4.3EPSS: 0%CPEs: 1EXPL: 0CVE-2023-47642 – Stream description leaks to ex-subscribers in Zulip
https://notcve.org/view.php?id=CVE-2023-47642
16 Nov 2023 — Zulip is an open-source team collaboration tool. It was discovered by the Zulip development team that active users who had previously been subscribed to a stream incorrectly continued being able to use the Zulip API to access metadata for that stream. As a result, users who had been removed from a stream, but still had an account in the organization, could still view metadata for that stream (including the stream name, description, settings, and an email address used to send emails into the stream via the i... • https://github.com/zulip/zulip/commit/6336322d2f9bbccaacfc80cba83a3c62eefd5737 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 6.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-32678 – Zulip vulnerable to insufficient authorization check for edition/deletion of messages and topics in private streams by former subscribers
https://notcve.org/view.php?id=CVE-2023-32678
25 Aug 2023 — Zulip is an open-source team collaboration tool with topic-based threading that combines email and chat. Users who used to be subscribed to a private stream and have been removed from it since retain the ability to edit messages/topics, move messages to other streams, and delete messages that they used to have access to, if other relevant organization permissions allow these actions. For example, a user may be able to edit or delete their old messages they posted in such a private stream. An administrator w... • https://github.com/zulip/zulip/security/advisories/GHSA-q3wg-jm9p-35fj • CWE-285: Improper Authorization •
CVSS: 3.7EPSS: 0%CPEs: 1EXPL: 0CVE-2022-41914 – Non-constant-time SCIM token comparison in Zulip Server
https://notcve.org/view.php?id=CVE-2022-41914
16 Nov 2022 — Zulip is an open-source team collaboration tool. For organizations with System for Cross-domain Identity Management(SCIM) account management enabled, Zulip Server 5.0 through 5.6 checked the SCIM bearer token using a comparator that did not run in constant time. Therefore, it might theoretically be possible for an attacker to infer the value of the token by performing a sophisticated timing analysis on a large number of failing requests. If successful, this would allow the attacker to impersonate the SCIM c... • https://github.com/zulip/zulip/commit/59edbfa4113d140d3e20126bc65f4d67b2a8ffe5 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVSS: 4.9EPSS: 0%CPEs: 1EXPL: 0CVE-2022-31134 – Zulip Server public data export contains attachments that are non-public
https://notcve.org/view.php?id=CVE-2022-31134
12 Jul 2022 — Zulip is an open-source team collaboration tool. Zulip Server versions 2.1.0 above have a user interface tool, accessible only to server owners and server administrators, which provides a way to download a "public data" export. While this export is only accessible to administrators, in many configurations server administrators are not expected to have access to private messages and private streams. However, the "public data" export which administrators could generate contained the attachment contents for al... • https://blog.zulip.com/2022/07/12/zulip-cloud-data-exports • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-434: Unrestricted Upload of File with Dangerous Type •
