This is a generic arbitrary-file-read primitive, so the fix must address the traversal itself, not any specific file.\n\nThe readable files include the server's own secrets, which turns this from information disclosure into full compromise: the ECDSA private key that signs access JWTs (`.keys/ecdsa_id`), the refresh-token salt (`.keys/legacySalt`), and `LaunchServer.json` (database credentials). With the signing key an attacker mints a valid access token for any account, including admins. That is a full authentication bypass. Pre-auth, default config, port 9274.\n\n**Affected:** GravitLauncher LaunchServer ≤ 5.7.11 (the LaunchServer application; the published `pro.gravit.launcher:*-api` Maven artifacts do not contain the vulnerable code).\n\n### Details\nIn `FileServerHandler.channelRead0`:\n\n```java\npath = Paths.get(IOHelper.getPathFromUrlFragment(uri)).normalize().toString().substring(1); // line 194\nFile file = base.resolve(path).toFile();                                     ","public_affected_ranges":["<= 5.7.11"]}],"null_published_at":"2026-11-05T19:10:21.425Z","source_updated_at":"2026-07-02T20:49:20.000Z","source_disclosed_at":"2026-07-02T20:49:18.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-05T03:47:11.081Z"}],"next_cursor":null,"snapshot_revision":"42594"}
