Cross-site Scripting in Mattermost
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | github.com/mattermost/mattermost-server/v5 | < 5.39.0 | 5.39.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
Mattermost 5.38 and earlier fails to sufficiently sanitize clipboard contents, which allows a user-assisted attacker to inject arbitrary web script in product deployments that explicitly disable the default CSP.
