EPSS · scored 2026-10-27

OpenClaw before 2026.3.22 contains a path traversal vulnerability in Windows media loaders that accepts remote-host file URLs and UNC-style paths before local-path validation. Attackers can exploit this by providing network-hosted file targets that are treated as local content, bypassing intended access restrictions.

  • WID-SEC-W-2026-0856OpenClaw: Mehrere SchwachstellenDeutsch2026-03-24csaf · cert_bundDE

    Ein Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um beliebigen Code auszuführen, erweiterte Berechtigungen – sogar Administratorrechte – zu erlangen, Daten zu manipulieren, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, einen Denial-of-Service-Zustand herbeizuführen oder andere, nicht näher spezifizierte Angriffe durchzuführen.

  • GHSA-98ch-45wp-ch47OpenClaw: Windows-compatible env override keys could bypass system.run approval binding2026-04-07ghsa · osvUS

    ## Summary Before OpenClaw 2026.4.2, system-run approval binding normalized environment override keys differently from host execution. Windows-compatible keys could be omitted from the approval binding while still being injected at execution time. ## Impact An approved command could run with attacker-chosen environment overrides that were not represented in the approval binding. This created an approval-integrity gap for affected host-exec flows. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.4.1` - Patched versions: `>= 2026.4.2` - Latest published npm version: `2026.4.1` ## Fix Commit(s) - `7eb094a00d80e9f6bf0e62f2c45d3b88ff67c04d` — align approval binding with execution-time env-key normalization ## Release Process Note The fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live. Thanks @iskindar for reporting, and thanks @wsparks-vc for coordination.

  • GHSA-h3x4-hc5v-v2gmOpenClaw: Windows media loaders accepted remote-host file URLs before local path validation2026-03-26ghsa · osvUS

    ## 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.

  • CVE-2026-34426OpenClaw - Approval Bypass via Environment Variable Normalization2026-04-02vendor · osvUS

    OpenClaw versions prior to commit b57b680 contain an approval bypass vulnerability due to inconsistent environment variable normalization between approval and execution paths, allowing attackers to inject attacker-controlled environment variables into execution without approval system validation. Attackers can exploit differing normalization logic to discard non-portable keys during approval processing while accepting them at execution time, bypassing operator review and potentially influencing runtime behavior including execution of attacker-controlled binaries.
