An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-56004 in the wild and no public exploit code.\n\nAffected product: openSUSE buildservice. 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-2026-56004/ (Markdown: https://insights.sbomify.com/CVE-2026-56004/index.md)","id":"CVE-2026-56004","markdown":"https://insights.sbomify.com/CVE-2026-56004/index.md","name":"CVE-2026-56004","record":{"aliases":["GHSA-f3xh-pcqp-fpcm","openSUSE-SU-2026:11189-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Open Build Service","requires_auth":"none","summary":"Attackers can execute arbitrary code by providing a malicious _service file to the mercurial handler in the Open Build Service tar_scm source service.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/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":"A shellcode injection in the mercurial handler of the obs tar_scm source service before version 0.12.4 could be used by attackers able to provide a _service file to execute code as the source service or the local user checking out the malicious services","ecosystems":["openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"obs-service-tar_scm: command injection via mercurial handler","id":"CVE-2026-56004","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"WordPress WP Activity Log plugin \u003c= 5.6.3.1 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-56005"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["0.12.4-1.1"],"introduced":["0"],"last_affected":[],"package":"obs-service-tar_scm","purl":"pkg:rpm/opensuse/obs-service-tar_scm\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:11189-1"}],"prev":{"headline":"libXfont2 computeProps Property Buffer Heap Buffer Overflow","id":"CVE-2026-56003"},"products":["buildservice"],"published":"2026-07-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-02","vendors":["openSUSE"]},"summary":"Attackers can execute arbitrary code by providing a malicious _service file to the mercurial handler in the Open Build Service tar_scm source service.","url":"https://insights.sbomify.com/CVE-2026-56004/"}
