It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-28927 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-28927/ (Markdown: https://insights.sbomify.com/CVE-2021-28927/index.md)","id":"CVE-2021-28927","markdown":"https://insights.sbomify.com/CVE-2021-28927/index.md","name":"CVE-2021-28927","record":{"aliases":["GHSA-7585-2mwm-5jvf"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"RetroArch TTS engine","requires_auth":"low_privilege","summary":"Attackers with filesystem write access can execute arbitrary code via command injection in RetroArch's Windows text-to-speech engine.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"retroarch","vendor":"libretro"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"The text-to-speech engine in libretro RetroArch for Windows 1.9.0 passes unsanitized input to PowerShell through platform_win32.c via the accessibility_speak_windows function, which allows attackers who have write access on filesystems that are used by RetroArch to execute code via command injection using specially a crafted file and directory names.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Command injection in n/a","id":"CVE-2021-28927","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Arbitrary file upload in Fork CMS","id":"CVE-2021-28931"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2021-28925"},"products":["n/a"],"published":"2021-04-07","related":[{"cvss_score":4.8,"headline":"libretro RetroArch file_stream.c filestream_vscanf out-of-bounds","id":"CVE-2025-9136","kev_date_added":null,"published":"2025-08-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"Attackers with filesystem write access can execute arbitrary code via command injection in RetroArch's Windows text-to-speech engine.","url":"https://insights.sbomify.com/CVE-2021-28927/"}
