Aliases CVE-2026-34426
Summary OpenClaw: Windows media loaders accepted remote-host file URLs before local path validation ## Summary Windows local-media handling accepted remote-host file URLs and UNC-style paths before local-path validation, so network-hosted file targets could be treated as local content. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2` ## Fix Commit(s) - `4fd7feb0fd4ec16c48ed983980dba79a09b3aaf5` - `93880717f1cd34feaa45e74e939b7a5256288901` ## Release Status The fix shipped in `v2026.3.22` and remains present in `v2026.3.23` and `v2026.3.23-2`. ## Code-Level Confirmation - src/infra/local-file-access.ts now rejects remote-host file: URLs and UNC/network paths as non-local input. - src/media/web-media.ts, src/media-understanding/attachments.normalize.ts, and src/agents/sandbox-paths.ts all route through the shared local-file guard. OpenClaw thanks @RacerZ-fighting, @Fushuling for reporting.
