CVE-2026-42885 Audiobookshelf: Path prefix bypass in filesystem existence check leaks out-of-scope file existence

Audiobookshelf 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.,...

CVE-2026-42885 : Audiobookshelf (self-hosted server) has a path-prefix bypass in the POST /api/filesystem/pathexists check. Before version 2.32.2, the code uses String.startsWith() to verify a resolved path is within a library folder, which fails for sibling directories with a shared prefix (for ...

GHSA-FFGH-3JRF-8WVH Weblate: Prefix-Based Repository Boundary Check Bypass via Symlink/Junction Path Prefix Collision

Impact Weblate repository-boundary validation relies on string prefix checks on resolved absolute paths. In multiple code paths, the check uses startswith against the repository root path. This is not path-segment aware and can be bypassed when the external path shares the same string prefix as t...

File Browser has an access rule bypass via HasPrefix without trailing separator in path matching

Hi, The Matches function in rules/rules.go uses strings.HasPrefix without a trailing directory separator when matching paths against access rules. A rule for /uploads also matches /uploadsbackup/, granting or denying access to unintended directories. Verified against v2.62.2 commit 860c19d. Detai...

SciTokens has an Authorization Bypass via Incorrect Scope Path Prefix Checking

Summary The Enforcer incorrectly validates scope paths by using a simple prefix match startswith. This allows a token with access to a specific path e.g., /john to also access sibling paths that start with the same prefix e.g., /johnathan, /johnny, which is an Authorization Bypass. Details File:...
