{"id":"CVE-2026-34510","aliases":["CVE-2026-34426","GHSA-98ch-45wp-ch47","GHSA-h3x4-hc5v-v2gm"],"url":"https://o3.security/vulnerability/CVE-2026-34510","summary":"OpenClaw < 2026.3.22 - Remote File URL Acceptance in Windows Media Loaders","details":"## Summary\n\nBefore 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.\n\n## Impact\n\nAn 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.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected versions: `<= 2026.4.1`\n- Patched versions: `>= 2026.4.2`\n- Latest published npm version: `2026.4.1`\n\n## Fix Commit(s)\n\n- `7eb094a00d80e9f6bf0e62f2c45d3b88ff67c04d` — align approval binding with execution-time env-key normalization\n\n## Release Process Note\n\nThe 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.\n\nThanks @iskindar for reporting, and thanks @wsparks-vc for coordination.","published":"2026-04-01T15:29:35.712Z","modified":"2026-10-28T02:30:31.000175598Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.4.2"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/4fd7feb0fd4ec16c48ed983980dba79a09b3aaf5","label":"openclaw/openclaw@4fd7feb"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34510.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-h3x4-hc5v-v2gm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34510"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-remote-file-url-acceptance-in-windows-media-loaders"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/4fd7feb0fd4ec16c48ed983980dba79a09b3aaf5"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/630f1479c44f78484dfa21bb407cbe6f171dac87"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/93880717f1cd34feaa45e74e939b7a5256288901"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-98ch-45wp-ch47"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/7eb094a00d80e9f6bf0e62f2c45d3b88ff67c04d"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:31.000175598Z"}}
