OpenClaw: Exported session HTML could keep unsafe markdown links
Summary
Exported session HTML could keep unsafe markdown links. In affected versions, content rendered into an exported session could preserve unsafe javascript: or data: links in generated HTML.
This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed.
Impact
When the affected feature is enabled and reachable, this could run browser-side script if a trusted operator opens the exported file and activates the link. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path.
Patched Versions
The first stable patched version is 2026.5.12.
Mitigations
do not open exported session HTML from untrusted content in a privileged browser profile until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
