{"cve":"CVE-2026-49410","nvd":{"published":"2026-10-16T22:17:23.490","modified":"2026-10-19T22:17:10.897","status":"Deferred","description":"OpenHuman is an open-source agent harness available as a desktop application and Rust library. Versions before 0.56.0 allow cross-site request forgery against the unauthenticated GET /auth/telegram loopback callback because telegram_auth_handler consumes an attacker-supplied one-time Telegram login token and passes the returned JWT to credentials::ops::store_session without validating browser fetch metadata or the request origin. An attacker with an OpenHuman account can cause a user with the local core running to visit a malicious page that requests the /auth/telegram endpoint on loopback port 7788, switching the user's active local session to the attacker's backend account and exposing subsequent agent actions, memory writes, and Telegram messages associated with that session to the attacker. This issue is fixed in version 0.56.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-352","CWE-384"],"references":["https://github.com/tinyhumansai/openhuman/commit/b1bbc53fceed7d1f0cff90cbb0a42f4ab8e153a1","https://github.com/tinyhumansai/openhuman/pull/2331","https://github.com/tinyhumansai/openhuman/releases/tag/v0.56.0","https://github.com/tinyhumansai/openhuman/security/advisories/GHSA-c4m9-hw7m-vv3m","https://github.com/tinyhumansai/openhuman/security/advisories/GHSA-c4m9-hw7m-vv3m"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-49410","score":0.00191,"percentile":0.08707,"date":"2026-10-25"},"kev":null,"osv":[],"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).
