{"id":"CVE-2026-109949","summary":"FreeRDP 3.0.0 before 3.32.0 PIN Brute-Force via Virtual Smartcard","details":"FreeRDP 3.0.0 before 3.32.0 contains an improper restriction of excessive authentication attempts in its virtual smartcard GIDS implementation, which stores the PIN retry counter per-handle. A malicious RDP server can exhaust the counter with VERIFY APDUs, then request a new SCardConnect to reset attempts, enabling unbounded online brute-forcing of the configured smartcard PIN.","aliases":["GHSA-chh2-527f-x255"],"modified":"2026-10-14T02:48:21.816734101Z","published":"2026-10-13T13:27:15.776Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-307"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109949.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109949.json"},{"type":"ADVISORY","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-chh2-527f-x255"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-109949"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/freerdp-3.0.0-before-3.32.0-pin-brute-force-via-virtual-smartcard"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freerdp/freerdp","events":[{"introduced":"a34fa7c49d2a39aa49ace1d7bea9656912d8c7cb"},{"fixed":"d27a4f7c1c63b62a5e60e5d939ad116cfb58ffc1"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"3.0.0"},{"fixed":"3.32.0"}]}}],"versions":["3.5.1","3.5.0","3.4.0","3.3.0","3.2.0","3.1.0","3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-109949.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
