{"schema":"threatline.record/2","record":{"id":"CVE-2026-100860","aliases":["GHSA-fmpw-hj3m-xvj6"],"summary":"heym before 0.0.105 Authentication Bypass via Redis Node","details":"heym before 0.0.105 does not act on the result of the credential authorization lookup in the Redis workflow node (backend/app/services/node_execution/nodes/redis_node.py). When _get_accessible_credential returns None — because the credential ID does not exist or the caller is not authorized to use it — the node treats the lookup failure as an empty configuration and falls back to defaults, connecting to localhost:6379 with no password and executing the requested operation there. The same fallback occurs when an accessible credential has an empty config or no redis_host value. An authenticated workflow author who supplies a credential ID they do not own, or one that was deleted, therefore obtains a read/write connection to whatever Redis is listening on the backend's loopback interface instead of an error. Impact depends on the deployment: the stock docker-compose.yml ships no Redis, in which case the flaw surfaces as a misleading connection error rather than data exposure.","categories":["Unclassified"],"product":"heym","vendor":"heymrun","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100860","source_modified_at":"2026-09-28T16:05:18.442Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"heym","vendor":"heymrun","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"0.0.105"},{"version":"0.0.105","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100860","source_modified_at":"2026-09-28T16:05:18.442Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"heym","ecosystem":null},"version":"0.0.105","basis":"first unaffected version stated in the CVE record"}],"cvss":6.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00115,"percentile":0.01483,"score_date":"2026-10-23"},"published_at":"2026-09-27T01:28:50.589Z","modified_at":"2026-09-28T16:05:18.442Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100860","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-28T16:05:18.442Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100860","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/heymrun/heym/security/advisories/GHSA-fmpw-hj3m-xvj6","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/heym-before-0.0.105-authentication-bypass-via-redis-node","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-28T16:04:55.751279Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-28T16:05:18.442Z","content_hash":"e61183be3e56c34da30384b1b3e64429de403373d7f572b844499a359c1e3ea4"}}
