{"id":"CVE-2026-100548","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-100548","generatedAt":"2026-10-28T01:47:58.398Z","title":"OpenClaw (npm package 'openclaw') versions >= 2026.3.28 and < 2026.8.1 contain a credential exposure issue in memory embedding failover.","description":"OpenClaw (npm package 'openclaw') versions >= 2026.3.28 and < 2026.8.1 contain a credential exposure issue in memory embedding failover. When remote embedding fallback is configured and the primary embedding provider fails, the request can be sent to a different fallback provider while still reusing the primary provider's configured API key, causing that credential to be transmitted as a bearer token to an unintended vendor. The practical impact depends on the configured providers, whether failover occurs, and the privileges attached to the primary provider key. The issue is fixed in 2026.8.1; as a workaround, disable cross-provider embedding fallback or configure each provider with separate, narrowly scoped credentials.","published":"2026-09-26T03:17:01.000Z","lastModified":"2026-09-30T01:16:34.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":6,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-200"],"affected":[],"epss":{"score":0.0025,"percentile":0.16236,"date":"2026-10-26","history":[{"date":"2026-09-26","score":0.0025,"percentile":0.14696}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.25%).
