Overview

CVE-2022-31017 is a low-severity vulnerability. It was published on June 25, 2022 and has a CVSS 3.1 base score of 2.0 (LOW).

This vulnerability has a CVSS 3.1 base score of 2.0, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Zulip is an open-source team collaboration tool. Versions 2.1.0 through and including 5.2 are vulnerable to a logic error. A stream configured as private with protected history, where new subscribers should not be allowed to see messages sent before they were subscribed, when edited causes the server to incorrectly send an API event that includes the edited message to all of the stream’s current subscribers. This API event is ignored by official clients, but can be observed by using a modified client or the browser’s developer tools. This bug will be fixed in Zulip Server 5.3. There are no known workarounds.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
