An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-123747 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\n\nAffected product: OpenPrinting Red Hat Enterprise Linux 10. 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-2026-123747/ (Markdown: https://insights.sbomify.com/CVE-2026-123747/index.md)","id":"CVE-2026-123747","markdown":"https://insights.sbomify.com/CVE-2026-123747/index.md","name":"CVE-2026-123747","record":{"aliases":["UBUNTU-CVE-2026-123747"],"analysis":{"component_type":"server_software","exploitable_when_present":false,"fix_type":"no_fix_stated","impacts":["data_modify","code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PostScript print server","requires_auth":"high_privilege","requires_specific_call":false,"summary":"Unauthenticated remote attackers can upload or delete arbitrary files via traversal in PPD filenames, possibly executing commands; pappl-retrofit operators should care.","user_interaction":"required","vuln_class":"path_traversal","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"redhat","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A flaw was found in pappl-retrofit.
