{"cve":"CVE-2026-48063","nvd":{"published":"2026-08-03T21:16:39.450","modified":"2026-09-10T20:31:16.483","status":"Deferred","description":"Baileys is a cocket-based TS/JavaScript API for WhatsApp Web. In versions prior to both 6.7.22 and 7.0.0-rc12, any Baileys session  can be sent a malicious payload via the placeholderResendMessage and trigger a fake messages.upsert event with a fake message key and payload. This allows anyone to spoof messages. The same exploit also allows an attacker to corrupt the app state sync system by sending fake key shares, and also allows for history sync spoofing which also serves the same problem, injecting fake previous context or \"on-demand\" sync. This issue has been fixed in versions 6.7.22 and 7.0.0-rc12.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":null,"cwes":["CWE-290","CWE-345","CWE-346"],"references":["https://github.com/WhiskeySockets/Baileys/commit/3beb08eecfcb4e65722e674034bd84fb11a9de35","https://github.com/WhiskeySockets/Baileys/security/advisories/GHSA-qvv5-jq5g-4cgg"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-48063","score":0.00223,"percentile":0.12943,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qvv5-jq5g-4cgg","url":"https://osv.dev/vulnerability/GHSA-qvv5-jq5g-4cgg","summary":"Baileys has message upsert / hist sync spoofing and app state corruption when using maliciously crafted protocolMessage payload","modified":"2026-09-10T03:50:50.292130508Z","packages":[{"ecosystem":"npm","name":"baileys","purl":"pkg:npm/baileys","ranges":["<6.7.22"],"fixed":["6.7.22"]},{"ecosystem":"npm","name":"@whiskeysockets/baileys","purl":"pkg:npm/%40whiskeysockets/baileys","ranges":["<6.7.22"],"fixed":["6.7.22"]},{"ecosystem":"npm","name":"baileys","purl":"pkg:npm/baileys","ranges":[">=7.0.0-rc.1 <7.0.0-rc12"],"fixed":["7.0.0-rc12"]},{"ecosystem":"npm","name":"@whiskeysockets/baileys","purl":"pkg:npm/%40whiskeysockets/baileys","ranges":[">=7.0.0-rc.1 <7.0.0-rc12"],"fixed":["7.0.0-rc12"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
