    Mattermost doesn't limit the size of the request body on the start meeting API endpoint

    CVE-2026-2325 · GHSA-m3p3-8frq-q7qh

    Affected
    • Go github.com/mattermost/mattermost-plugin-msteams-meetings < 1.1.1-0.20260213105619-c5892dd169de
    Fixed in

    Issue
    Mattermost versions 11.5.x <= 11.5.1, 10.11.x <= 10.11.13, 11.4.x <= 11.4.3 fail to limit the size of the request body on the start meeting API endpoint, which allows an authenticated attacker to cause resource exhaustion or denial of service via a crafted oversized HTTP POST request to {{/api/v1/meetings}}.. Mattermost Advisory ID: MMSA-2026-00608

    Recommended action: Upgrade to 1.1.1-0.20260213105619-c5892dd169de (pre-release) or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
