CVE-2024-47003
Mattermost
CVE-2024-47003: Mattermost versions 9.11.x and 9.5.x suffer from a vulnerability where the system doesn't properly validate the message type of permalink posts. This allows an attacker to crash the frontend by sending a non-string value as the message. The vulnerability, while having a CVSS score of 6.5, has a SOCRadar Vulnerability Risk Score (SVRS) of 61, indicating a moderate risk. Although not critical (SVRS > 80), its presence "In The Wild" increases the potential for exploitation. Successful exploitation could lead to denial of service for users accessing affected Mattermost instances. Immediate patching is not mandatory, but monitoring for suspicious activity and applying updates when available is recommended to prevent potential disruptions. This is significant because it impacts the availability of the communication platform.
