It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-55480 exists.\n\nAffected product: OpenPrinting cups. 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-2026-55480/ (Markdown: https://insights.sbomify.com/CVE-2026-55480/index.md)","id":"CVE-2026-55480","markdown":"https://insights.sbomify.com/CVE-2026-55480/index.md","name":"CVE-2026-55480","record":{"aliases":["AZL-108284","BELL-CVE-2026-55480","DEBIAN-CVE-2026-55480","ECHO-ffb1-08bb-e5b4","GHSA-jj94-x3qh-ffp9","UBUNTU-CVE-2026-55480"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"CUPS printing system","requires_auth":"high_privilege","summary":"A local attacker with lp-group access can exploit a race condition in CUPS to overwrite root-owned files via symlink attacks during printer model copying.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cups","vendor":"openprinting"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"},{"id":"CWE-377","name":"DEPRECATED: Insecure Temporary File"}],"description":"OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to 2.4.20, copy_model() in scheduler/ipp.c creates a predictable TempDir/\u003cconnection-number\u003e.ppd path in an lp-group-writable directory and opens it as root without O_EXCL or O_NOFOLLOW. Exploitation requires an lp-group process able to write that directory to predict the connection-derived name and plant a symlink before the root open, while a privileged add-printer or modify-printer operation using a model PPD triggers copy_model(). The reporter treats an existing lp foothold and the privileged operation as distinct prerequisites, while the maintainer assesses high privileges because installing the relevant filter or administering the printer requires root or print-administrator access. If the race succeeds, the root scheduler follows the symlink and truncates or overwrites a root-writable target with generated PPD data, compromising file integrity or availability. This issue is fixed in version 2.4.20.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"CUPS copy_model() creates a predictable PPD tempfile without O_EXCL/O_NOFOLLOW (symlink TOCTOU, lp → root)","id":"CVE-2026-55480","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Snipe-IT: CSS Injection via `header_color` Setting","id":"CVE-2026-55481"},"packages":[],"prev":{"headline":"Snipe-IT: Incorrect permission for legacy license checkin API","id":"CVE-2026-55479"},"products":["cups"],"published":"2026-10-15","related":[{"cvss_score":8,"headline":"cups has Authentication bypass with AuthType Negotiate","id":"CVE-2025-58060","kev_date_added":null,"published":"2025-09-11"},{"cvss_score":6.5,"headline":"Path traversal in cups","id":"CVE-2026-34978","kev_date_added":null,"published":"2026-04-03"},{"cvss_score":6.5,"headline":"cups: Remote DoS via null dereference","id":"CVE-2025-58364","kev_date_added":null,"published":"2025-09-11"},{"cvss_score":6.1,"headline":"OpenPrinting CUPS: Shared PostScript queue lets anonymous Print-Job requests reach `lp` code execution over the network","id":"CVE-2026-34980","kev_date_added":null,"published":"2026-04-03"},{"cvss_score":6,"headline":"OpenPrinting CUPS vulnerable to stack based out-of-bound write","id":"CVE-2025-61915","kev_date_added":null,"published":"2025-11-29"},{"cvss_score":5.3,"headline":"OpenPrinting CUPS: root-side banner file disclosure","id":"CVE-2026-61702","kev_date_added":null,"published":"2026-10-15"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-20","vendors":["OpenPrinting"]},"summary":"A local attacker with lp-group access can exploit a race condition in CUPS to overwrite root-owned files via symlink attacks during printer model copying.","url":"https://insights.sbomify.com/CVE-2026-55480/"}
