CVE-2026-55543

Severity not reported

Data quality: partial. Some fields were not provided by the source.

TuxGuitar is an open-source guitar tablature editor.

TuxGuitar is an open-source guitar tablature editor. Prior to 2.1.0, an untrusted .tg file can set gervil.soundbank.path to reference an on-disk archive, including the .tg file itself, whose META-INF/services/javax.sound.midi.Soundbank entry names an attacker-supplied class stored in that archive. When a user opens the file, JARSoundbankReader uses an unverified class loader to load and instantiate that class, executing its constructor with the privileges of the TuxGuitar process. This issue is fixed in version 2.1.0.
