**Name of the Vulnerable Software and Affected Versions**
zulip/zulip versions 44f935695d452cc3fb16845a0c6af710438b153d through 3eb2791c3e9695f7d37ffe84e0c2184fae665cb6
**Description**
The issue is related to Cross-site Scripting (XSS) - Stored, which affects the GitHub repository zulip/zulip. This type of attack occurs when an application stores user input that contains malicious scripts, which are then executed by the application, allowing an attacker to perform unauthorized actions.
**Recommendations**
For versions 44f935695d452cc3fb16845a0c6af710438b153d through 3eb2791c3e9695f7d37ffe84e0c2184fae665cb6, update to a version after 3eb2791c3e9695f7d37ffe84e0c2184fae665cb6 to resolve the issue.
As a temporary workaround, consider restricting user input to prevent the storage of malicious scripts until a patch is available.
