It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-55543 exists.\n\nAffected product: helge17 tuxguitar. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-55543/ (Markdown: https://insights.sbomify.com/CVE-2026-55543/index.md)","id":"CVE-2026-55543","markdown":"https://insights.sbomify.com/CVE-2026-55543/index.md","name":"CVE-2026-55543","record":{"aliases":["DEBIAN-CVE-2026-55543","GHSA-v66p-c82h-w3cq","UBUNTU-CVE-2026-55543","openSUSE-SU-2026:11645-1"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Guitar tablature editor","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into opening a malicious .tg file that loads an unverified class from an embedded archive.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-470","name":"Use of Externally-Controlled Input to Select Classes or Code"}],"description":"TuxGuitar is an open-source guitar tablature editor.
