| Package | Affected versions | Patched versions |
|---|---|---|
| mattermost server | ≥ 9.5.0, < 9.5.9 | 9.5.9 |
Mattermost versions 9.5.x <= 9.5.8 fail to include the metadata endpoints of Oracle Cloud and Alibaba in the SSRF denylist, which allows an attacker to possibly cause an SSRF if Mattermost was deployed in Oracle Cloud or Alibaba.
