Summary

### Summary Sandbox media handling had a time-of-check/time-of-use gap: media paths could be validated first and read later through a separate path. A symlink retarget between those steps could cause reads outside `sandboxRoot`.

### Impact Affected versions could permit host file reads outside the intended sandbox root in media attachment/image flows.

### Fix Media reads now use consolidated root-scoped, boundary-safe read paths at use time, removing check/use drift across call sites.

### Affected and Patched Versions - Affected: `<= 2026.2.26` - Patched: `2026.3.1`

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of openclaw/openclaw published their own advisory on GitHub. Reviewed sources take precedence over it.
