A remote attacker with a valid session token could read any file that the target user can access. This access includes the PlexOnlineToken, which grants control of the Plex account and server. A LAN-adjacent attacker with a client-supplied X-Forwarded-For header could exploit the same issue.","published_at":"2026-09-23T16:06:00.176000Z","last_modified_at":"2026-09-29T18:36:43.750000Z","cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":7.1,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-22"],"nvd_references":["https://raw.githubusercontent.com/cisagov/CSAF/develop/csaf_files/IT/white/2026/va-26-266-01.json","https://www.cve.org/CVERecord?id=CVE-2026-96651","https://forums.plex.tv/t/plex-media-server/30447/711","https://zmain.info/blog/plex2shell"],"vuln_status":"Analyzed","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":"2026-09-23T16:33:11.659249Z","updated_at":"2026-10-02T10:03:01.593453Z"},"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":"L","value_label":"Low"},{"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":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"plex","vendor_name":"Plex","product_slug":"media-server","product_name":"Media Server","version_start":"0","version_start_inclusive":true,"version_end":"1.43.3.10861","version_end_inclusive":false,"cpe23_uri":"cve5:plex:media-server:0:1.43.3.10861"},{"vendor_slug":"plex","vendor_name":"Plex","product_slug":"media-server","product_name":"Media Server","version_start":"1.43.3.10861","version_start_inclusive":true,"version_end":"1.43.3.10861","version_end_inclusive":true,"cpe23_uri":"cve5:plex:media-server:1.43.3.10861:1.43.3.10861"},{"vendor_slug":"plex","vendor_name":"Plex","product_slug":"media-server","product_name":"Media Server","version_start":null,"version_start_inclusive":null,"version_end":"1.43.0.10861","version_end_inclusive":false,"cpe23_uri":"cpe:2.3:a:plex:media_server:*:*:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://raw.githubusercontent.com/cisagov/CSAF/develop/csaf_files/IT/white/2026/va-26-266-01.json","source_type":"MISC","tags":[]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-96651","source_type":"CONFIRM","tags":[]},{"url":"https://forums.plex.tv/t/plex-media-server/30447/711","source_type":"MISC","tags":[]},{"url":"https://zmain.info/blog/plex2shell","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-09-23T16:06:00.176000Z","label":"CVE published","source":null}]}
