{"cve":"CVE-2025-55210","nvd":{"published":"2026-02-12T17:16:04.963","modified":"2026-06-17T09:41:27.790","status":"Analyzed","description":"FreePBX is an open-source web-based graphical user interface (GUI) that manages Asterisk. Prior to 17.0.5 and 16.0.17, FreePBX module api (PBX API) is vulnerable to privilege escalation by authenticated users with REST/GraphQL API access. This vulnerability allows an attacker to forge a valid JWT with full access to the REST and GraphQL APIs on a FreePBX that they've already connected to, possibly as a lower privileged user. The JWT is signed using the api-oauth.key private key. An attacker can generate their own token if they possess this key (e.g., by accessing an affected instance), and specify any scopes they wish (e.g., rest, gql), bypassing traditional authorization checks. However, FreePBX enforces that the jti (JWT ID) claim must exist in the database (api_access_tokens table in the asterisk MySQL database) in order for the token to be accepted. Therefore, the attacker must know a jti value that already exists on the target instance. This vulnerability is fixed in 17.0.5 and 16.0.17.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:A/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":2.0},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5},"cwes":["CWE-270"],"references":["https://github.com/FreePBX/api/commit/bc6f7d72063cffb18babb6559fa351046d7ad19b","https://github.com/FreePBX/api/commit/c16a3a79b83382fb4884e51174882ed635637002","https://github.com/FreePBX/api/commit/d66786634e7e7d3eedcb4d0931b32c415ba6e9ef","https://github.com/FreePBX/security-reporting/security/advisories/GHSA-gvgh-p7wj-76cf"],"products":["sangoma:freepbx"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2025-55210","score":0.00344,"percentile":0.27968,"date":"2026-11-01"},"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).
