CVE-2023-45316: Reflected client side path traversal leading to CSRF in Playbooks

First published: Tue Dec 12 2023(Updated: )

Mattermost fails to validate if a relative path is passed in /plugins/playbooks/api/v0/telemetry/run/<telem_run_id> as a telemetry run ID, allowing an attacker to use a path traversal payload that points to a different endpoint leading to a CSRF attack.
