CVE-2026-73085MEDIUM | Audiobookshelf: Refresh Token Accepted on Resource EndpointsAudiobookshelf is a self-hosted audiobook and podcast server. Prior to 2.36.0, the jwtAuthCheck function in server/auth/TokenManager.js treats JWTs with the refresh token type as bearer access tokens on API and WebSocket resource endpoints such as /api/me instead of restricting them to /auth/refresh, allowing refresh tokens to authenticate as the associated users. This issue is fixed in version 2.36.0. CWE-287Aug 11, 2026 | CVSS5.3v4.0 | EPSS0.267% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-71209HIGH | audiobookshelf - %2F Encoding Discrepancy Bypasses Cover/Image Auth Exemption Regex, Enabling Unauthenticated Path Traversalaudiobookshelf's authentication-exemption check (server/routers/Auth.js) matches unauthenticated-allowed GET routes against req.path via a regex requiring a literal /items/:id/cover or /authors/:id/image shape, where req.path retains %2F sequences URL-encoded. CacheManager.handleCoverCache then joins this decoded value into a cache file path and streams the result before any database-backed ownership check. | CVSS7.5v3.1 | EPSS1.76% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware use1 Nuclei template | STIX |
CVE-2026-42888MEDIUM | Audiobookshelf: Path Traversal vulnerability in the audiobookshelf projectAudiobookshelf is a self-hosted audiobook and podcast server. Prior to 2.32.2, the podcast creation endpoint at server/controllers/PodcastController.js accepts a user-controlled file path without sufficient boundary validation to ensure it remains within the intended library directory.

CVE-2026-42886MEDIUM | Audiobookshelf: Memory amplification DoS via oversized compressed details entry in backup uploadAudiobookshelf is a self-hosted audiobook and podcast server. Prior to 2.32.2, the POST /api/backups/upload endpoint decompresses the details entry from an uploaded .audiobookshelf ZIP file entirely into memory using zip.entryData(), with no limit on the decompressed size. The upload middleware also has no file size limit. An admin user can upload a crafted ZIP containing a highly compressed details entry that, when decompressed, consumes hundreds of megabytes or gigabytes of memory, crashing th… CWE-409May 11, 2026 | CVSS4.9v3.1 | EPSS0.257% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-42885MEDIUM | Audiobookshelf: Path prefix bypass in filesystem existence check leaks out-of-scope file existenceAudiobookshelf is a self-hosted audiobook and podcast server. Prior to 2.32.2, the POST /api/filesystem/pathexists endpoint uses String.startsWith() to validate that a resolved file path is within a library folder. This check fails for sibling directories whose names share a common prefix (e.g., /audiobooks vs /audiobooks-private), allowing authenticated users with upload permission to probe file existence outside their authorized library folder boundaries. This vulnerability is fixed in 2.32.2. CWE-22May 11, 2026 | CVSS4.3v3.1 | EPSS0.236% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-42884MEDIUM | Audiobookshelf: Collection endpoints bypass library access controls exposing restricted library dataAudiobookshelf is a self-hosted audiobook and podcast server. Prior to 2.32.2, the GET /api/collections and GET /api/collections/:id endpoints return collections from all libraries without checking whether the requesting user has access to each collection's library. An authenticated user with access to any library can enumerate and read collections (including full book metadata) from libraries they are explicitly restricted from accessing. This vulnerability is fixed in 2.32.2. CWE-863May 11, 2026 | CVSS4.3v3.1 | EPSS0.162% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-42883MEDIUM | Audiobookshelf: Cross-library file exfiltration via unscoped bulk download endpointAudiobookshelf is a self-hosted audiobook and podcast server. Prior to 2.32.2, the GET /api/libraries/:id/download endpoint validates that the requesting user has access to the library specified in the URL path, but fetches downloadable items solely by attacker-provided IDs without constraining them to that library. An authenticated user with download permission and access to any one library can exfiltrate the full file contents of items belonging to any other library, including libraries they a… CWE-863May 11, 2026 | CVSS6.5v3.1 | EPSS0.205% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |

CVE-2025-57800HIGH | Audiobookshelf vulnerable to OIDC token exfiltration and account takeoverAudiobookshelf is an open-source self-hosted audiobook server. In versions 2.6.0 through 2.26.3, the application does not properly restrict redirect callback URLs during OIDC authentication. An attacker can craft a login link that causes Audiobookshelf to store an arbitrary callback in a cookie, which is later used to redirect the user after authentication. The server then issues a 302 redirect to the attacker-controlled URL, appending sensitive OIDC tokens as query parameters. This allows an at… | CVSS8.8v3.1 | EPSS0.456% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2025-46338MEDIUM | Audiobookshelf Vulnerable to Cross-Site-Scripting Reflected via POST Request in /api/uploadAudiobookshelf is a self-hosted audiobook and podcast server. Prior to version 2.21.0, an improper input handling vulnerability in the `/api/upload` endpoint allows an attacker to perform a reflected cross-site scripting (XSS) attack by submitting malicious payloads in the `libraryId` field. The unsanitized input is reflected in the server’s error message, enabling arbitrary JavaScript execution in a victim's browser. This issue has been patched in version 2.21.0. CWE-79Apr 29, 2025 | CVSS6.9v4.0 | EPSS0.339% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2025-25205HIGH | Remote Authentication-Bypass can lead to server crash or limited information disclosure due to faulty pattern matchingAudiobookshelf is a self-hosted audiobook and podcast server. 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 otherwi… | CVSS8.2v3.1 | EPSS4.22% | PoCs1 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2024-43797MEDIUM | Path Traversal in audiobookshelfaudiobookshelf is a self-hosted audiobook and podcast server. A non-admin user is not allowed to create libraries (or access only the ones they have permission to). However, the `LibraryController` is missing the check for admin user and thus allows a path traversal issue. Allowing non-admin users to write to any directory in the system can be seen as a form of path traversal. However, since it can be restricted to only admin permissions, fixing this is relatively simple and falls more into the … CWE-22Sep 2, 2024 | CVSS6.3v3.1 | EPSS0.546% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2024-35236MEDIUM | Audiobookshelf Cross-Site-Scripting vulnerability via crafted ebooksAudiobookshelf is a self-hosted audiobook and podcast server. Prior to version 2.10.0, opening an ebook with malicious scripts inside leads to code execution inside the browsing context. Attacking a user with high privileges (upload, creation of libraries) can lead to remote code execution (RCE) in the worst case. This was tested on version 2.9.0 on Windows, but an arbitrary file write is powerful enough as is and should easily lead to RCE on Linux, too. Version 2.10.0 contains a patch for the v… CWE-79May 27, 2024 | CVSS4.8v3.1 | EPSS0.838% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
