HFS user adding a "web link" in HFS is vulnerable to "target=_blank" exploit
- Severity:
- Low
Description
When adding a “web link” to the HFS virtual filesystem, the frontend opens it with target="_blank" but without the rel="noopener noreferrer" attribute. This allows the opened page to use the window.opener property to change the location of the original HFS tab.
Recommendation
Update the hfs package to the latest compatible version. Followings are version details:
- Affected version(s): <= 0.57.9
- Patched version(s): 0.57.10
