    ## Summary QQBot reply media URL handling could trigger SSRF and re-upload fetched bytes. ## Affected Packages / Versions - Package: `openclaw` - Ecosystem: npm - Affected versions: `< 2026.4.12` - Patched versions: `>= 2026.4.12` ## Impact QQBot reply media URLs could be treated as trusted media sources, allowing SSRF fetches whose returned bytes were then re-uploaded through the channel. ## Technical Details The fix routes QQBot remote media fetches through SSRF-guarded media fetching and explicit URL allowlist policy. ## Fix The issue was fixed in #63495 and #65788. The first stable tag containing the fix is `v2026.4.12`, and `openclaw@2026.4.14` includes the fix. ## Fix Commit(s) - `08ae021d1f4f02e0ca5fd8a3b9659291c1ecf95a` - `ddb7a8dd80b8d5dd04aafa44ce7a4354b568bb2d` - PR: #63495, #65788 ## Release Process Note Users should upgrade to `openclaw` 2026.4.12 or newer.
