{"id":"CVE-2026-110873","summary":"Heym 0.0.55 before 0.0.121 Credential Theft via error_workflow_id Field","details":"Heym from 0.0.55 before 0.0.121 contains a privilege escalation vulnerability that allows shared collaborators to overwrite a workflow's error_workflow_id because the field is missing from OWNER_ONLY_EXECUTION_FIELDS. Attackers can point the error workflow to their own workflow with an HTTP node, and when the parent workflow errors the owner's decrypted credentials are injected and exfiltrated.","aliases":["GHSA-c3f4-2mrj-jfqr"],"modified":"2026-10-16T02:47:40.166706504Z","published":"2026-10-14T22:53:01.452Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110873.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110873.json"},{"type":"ADVISORY","url":"https://github.com/heymrun/heym/security/advisories/GHSA-c3f4-2mrj-jfqr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110873"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/heym-0.0.55-before-0.0.121-credential-theft-via-error-workflow-id-field"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/heymrun/heym","events":[{"introduced":"f57819f16aa8c4455d7216e7854c7e5df86d4e19"},{"fixed":"3cdd947388abe09ba1c9d258a133046665e018d7"}],"database_specific":{"extracted_events":[{"introduced":"0.0.55"},{"fixed":"0.0.121"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v0.0.120","v0.0.119","v0.0.118","v0.0.117","v0.0.116","v0.0.115","v0.0.114","v0.0.113","v0.0.112","v0.0.111","v0.0.110","v0.0.109","v0.0.108","v0.0.107","v0.0.106","v0.0.105","v0.0.104","v0.0.103","v0.0.102","v0.0.101","v0.0.100","v0.0.99","v0.0.98","v0.0.97","v0.0.96","v0.0.95","v0.0.94","v0.0.93","v0.0.92","v0.0.91","v0.0.90","v0.0.89","v0.0.88","v0.0.87","v0.0.86","v0.0.85","v0.0.84","v0.0.83","v0.0.82","v0.0.81","v0.0.79","v0.0.80","v0.0.78","v0.0.77","v0.0.76","v0.0.75","v0.0.74","0.0.73","v0.0.72","opencode-pr-assets","0.0.71","codex-pr-assets","0.0.70","v0.0.69","v0.0.68","v0.0.67","v0.0.66","v0.0.65","v0.0.64","v0.0.63","v0.0.62","v0.0.61","v0.0.60","v0.0.59","v0.0.58","v0.0.57","v0.0.56","v0.0.55"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110873.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
