Starting in version 2.17.0 and prior to version 2.19.1, a flaw in the authentication bypass logic allows unauthenticated requests to match certain unanchored regex patterns in the URL. Attackers can craft URLs containing substrings like \"/api/items/1/cover\" in a query parameter (?r=/api/items/1/cover) to partially bypass authentication or trigger server crashes under certain routes. This could lead to information disclosure of otherwise protected data and, in some cases, a complete denial of service (server crash) if downstream code expects an authenticated user object. Version 2.19.1 contains a patch for the issue.","published_at":"2025-02-12T18:16:01.326000Z","last_modified_at":null,"cvss_v3_score":8.2,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","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-202","CWE-287","CWE-400"],"nvd_references":["https://github.com/advplyr/audiobookshelf/security/advisories/GHSA-pg8v-5jcv-wrvw","https://github.com/advplyr/audiobookshelf/pull/3584","https://github.com/advplyr/audiobookshelf/commit/bf8407274e3ee300af1927ee660d078a7a801e1c","https://github.com/advplyr/audiobookshelf/commit/ec6537656925a43871b07cfee12c9f383844d224","https://github.com/advplyr/audiobookshelf/blob/1a3d70d04100924d41391acb55bd8ddca486a4fa/server/Auth.js#L17-L41"],"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":"2026-06-28T23:26:00.382581Z"},"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":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"advplyr","vendor_name":"advplyr","product_slug":"audiobookshelf","product_name":"audiobookshelf","version_start":">= 2.17.0, < 2.19.1","version_start_inclusive":true,"version_end":">= 2.17.0, < 2.19.1","version_end_inclusive":true,"cpe23_uri":"cve5:advplyr:audiobookshelf:>= 2.17.0, < 2.19.1:>= 2.17.0, < 2.19.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/advplyr/audiobookshelf/security/advisories/GHSA-pg8v-5jcv-wrvw","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/advplyr/audiobookshelf/pull/3584","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/advplyr/audiobookshelf/commit/bf8407274e3ee300af1927ee660d078a7a801e1c","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/advplyr/audiobookshelf/commit/ec6537656925a43871b07cfee12c9f383844d224","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/advplyr/audiobookshelf/blob/1a3d70d04100924d41391acb55bd8ddca486a4fa/server/Auth.js#L17-L41","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2025-02-12T18:16:01.326000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:43:59.666099Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:43:59.666099Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:43:59.666099Z","label":"CVSS score revised","source":"cvelistv5"}]}
