{"id":"CVE-2025-71388","summary":"stoatchat 20241213-1 Webhook Token Disclosure via Read Permissions","details":"stoatchat (delta/Revolt) versions from 20241213-1 before 20250210-1 allow users with only ViewChannel (read) permission on a channel to fetch that channel's webhooks, including their tokens, because the webhook fetch endpoint checked for ViewChannel instead of ManageWebhooks. Using a retrieved token, an attacker can send arbitrary messages to the channel, bypassing channel permissions and impersonating a bot or webhook. Fixed in 20250210-1 (0.8.2).","aliases":["GHSA-8684-rvfj-v3jq"],"modified":"2026-07-18T03:45:38.959339213Z","published":"2026-07-16T12:19:15.310Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71388.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71388.json"},{"type":"ADVISORY","url":"https://github.com/stoatchat/stoatchat/security/advisories/GHSA-8684-rvfj-v3jq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71388"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/stoatchat-20241213-1-webhook-token-disclosure-via-read-permissions"},{"type":"FIX","url":"https://github.com/stoatchat/stoatchat/commit/e3723d647effb81ea3d3919d848faf64dbe89829"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/stoatchat/stoatchat","events":[{"introduced":"4c46054bff5e4a61f94c38e43fd3017f68837c1b"},{"fixed":"eb5f5f91cdd2eb37b4b99ed66b90887b8c6f4895"},{"fixed":"e3723d647effb81ea3d3919d848faf64dbe89829"}],"database_specific":{"extracted_events":[{"introduced":"20241213-1"},{"fixed":"20250210-1"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["20241227-2","20241227-1","20241226-1","20241222-6","20241222-5","20241222-4","20241222-3","20241222-2","20241222-1","20241220-1","20241213-1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71388.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
