Prior to version 8.0.0, the session expiration check in `library/auth.inc.php` runs only when `skip_timeout_reset` is not present in the request. When `skip_timeout_reset=1` is sent, the entire block that calls `SessionTracker::isSessionExpired()` and forces logout on timeout is skipped. As a result, any request that includes this parameter (e.g. from auto-refresh pages like the Patient Flow Board) never runs the expiration check: expired sessions can continue to access data indefinitely, abandoned workstations stay active, and an attacker with a stolen session cookie can keep sending `skip_timeout_reset=1` to avoid being logged out. Version 8.0.0 fixes the issue.","published_at":"2026-02-25T18:28:29.881000Z","last_modified_at":null,"cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-613"],"nvd_references":["https://github.com/openemr/openemr/security/advisories/GHSA-gx7q-6fhr-5h33","https://github.com/openemr/openemr/commit/02a6a7793402b10356a94626d78e0e1069e92a77"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:25.440717Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"openemr","vendor_name":"openemr","product_slug":"openemr","product_name":"openemr","version_start":"< 8.0.0","version_start_inclusive":true,"version_end":"< 8.0.0","version_end_inclusive":true,"cpe23_uri":"cve5:openemr:openemr:< 8.0.0:< 8.0.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/openemr/openemr/security/advisories/GHSA-gx7q-6fhr-5h33","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/openemr/openemr/commit/02a6a7793402b10356a94626d78e0e1069e92a77","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-02-25T18:28:29.881000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:05.081614Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:05.081614Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:05.081614Z","label":"CVSS score revised","source":"cvelistv5"}]}
