Technical Details

NVD Description

## Summary Discord event cover images bypassed sandbox media normalization. ## Affected Packages / Versions - Package: `openclaw` - Ecosystem: npm - Affected versions: `>= 2026.4.7 < 2026.4.10` - Patched versions: `>= 2026.4.10` ## Impact Discord event cover image parameters could bypass the sandbox media normalization path used for outbound local media, allowing host-local media references to reach a channel action path that expected normalized media. ## Technical Details The fix includes Discord `eventCreate.image` in sandbox media normalization and adds coverage for the event-create media path. ## Fix The issue was fixed in #64377. The first stable tag containing the fix is `v2026.4.10`, and `openclaw@2026.4.14` includes the fix. ## Fix Commit(s) - `979c6f09d6fad96596feb91c905934be7e0b4f15` - PR: #64377 ## Release Process Note Users should upgrade to `openclaw` 2026.4.10 or newer. The latest npm release, `2026.4.14`, already includes the fix. ## Credits Thanks to @zsxsoft, with sponsorship from @KeenSecurityLab and @qclawer for reporting this issue.
