{"schema":"threatline.record/2","record":{"id":"CVE-2026-100862","aliases":["GHSA-6x65-w7q7-wg93"],"summary":"heym before 0.0.91 Multiple Secrets Plaintext Storage","details":"heym, a workflow automation platform, stores and returns multiple capability secrets in plaintext in versions prior to 0.0.91. Affected secrets include webhook header-auth values (returned in cleartext by GET /api/workflows/{id} and persisted unsanitized into execution history), MCP API keys (stored as a plaintext column, returned in config/list responses, and accepted via the ?key= query string so they leak into logs, proxies and Referer headers), portal session tokens (stored and validated by plaintext equality with a 168-hour TTL), workflow execution JWTs (stored in full and re-listed by GET .../execution-tokens), Discord interaction tokens (the full interaction body is stored in execution history), and global variables. A user with read access to a workflow, share/team membership, or anyone able to read the database, a backup, or logs can recover these secrets and replay them to execute workflows or act as the secret owner.","categories":["Unclassified"],"product":"heym","vendor":"heymrun","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100862","source_modified_at":"2026-09-30T15:49:32.160Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"heym","vendor":"heymrun","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"0.0.91"},{"version":"0.0.91","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100862","source_modified_at":"2026-09-30T15:49:32.160Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"heym","ecosystem":null},"version":"0.0.91","basis":"first unaffected version stated in the CVE record"}],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00194,"percentile":0.08583,"score_date":"2026-10-23"},"published_at":"2026-09-27T01:28:51.915Z","modified_at":"2026-09-30T15:49:32.160Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100862","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T15:49:32.160Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100862","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-6x65-w7q7-wg93","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/heym-before-0.0.91-multiple-secrets-plaintext-storage","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-30T15:49:19.062351Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T15:49:32.160Z","content_hash":"56a55a01159bde6deb69de15870026da25d3f340c80c7fafe8301ba0d9e2ea9f"}}
