Prior to 4.13.0, the psd print sessions dump CLI command in coturn takes a filename argument and directly passes it to fopen with no path validation. An authenticated admin with CLI access can overwrite arbitrary files writable by the coturn process because the command string is used as-is after stripping the psd prefix and leading spaces, allowing truncation and overwrite with session dump data. This issue is fixed in version 4.13.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H","score":6.0},"cwes":["CWE-73"],"references":["https://github.com/coturn/coturn/commit/e72930f571beba3bc7a9f97661af2614aae92a55","https://github.com/coturn/coturn/releases/tag/4.13.0","https://github.com/coturn/coturn/security/advisories/GHSA-jj76-vwjw-w34r","https://github.com/coturn/coturn/security/advisories/GHSA-jj76-vwjw-w34r"],"products":["coturn_project:coturn"],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-53449","score":0.00207,"percentile":0.10806,"date":"2026-10-31"},"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).
