{"id":"CVE-2026-61643","summary":"FastGPT: workflow runtime can execute another user's private HTTP toolset","details":"FastGPT is a knowledge-based AI application platform. From 4.14.17 until 4.15.0-beta5, an authenticated FastGPT user can save a workflow node that points to another user's private HTTP toolset by using a crafted saved tool id such as http-\u003cvictim_toolset_app_id\u003e/\u003ctool_name\u003e. The normal toolset routes deny access, but the workflow save and runtime path did not apply the same authorization check to the referenced toolset, allowing /api/v2/chat/completions to resolve the saved reference and execute the victim-owned HTTP tool. This issue is fixed in version 4.15.0-beta5.","aliases":["GHSA-93r3-wqq3-c5ch"],"modified":"2026-07-17T03:48:21.950408834Z","published":"2026-07-15T17:03:22.325Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61643.json"},"references":[{"type":"WEB","url":"https://github.com/labring/FastGPT/releases/tag/v4.15.0-beta5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61643.json"},{"type":"ADVISORY","url":"https://github.com/labring/FastGPT/security/advisories/GHSA-93r3-wqq3-c5ch"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61643"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/labring/fastgpt","events":[{"introduced":"b1b97cbdebb9dc2a1c7b60cd9cd59d52d15c08e4"},{"fixed":"0c1840c7773c5be5d777f86228651479e02155db"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"4.14.17"},{"fixed":"4.15.0-beta5"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61643.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:N"}]}
