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-2026-105326 in the wild and no public exploit code.\n\nAffected product: 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-2026-105326/ (Markdown: https://insights.sbomify.com/CVE-2026-105326/index.md)","id":"CVE-2026-105326","markdown":"https://insights.sbomify.com/CVE-2026-105326/index.md","name":"CVE-2026-105326","record":{"aliases":["AZL-106743","BELL-CVE-2026-105326","DEBIAN-CVE-2026-105326","ECHO-b398-2098-0d6b","GHSA-r4wf-366f-f6g3","RHSA-2026:77638","UBUNTU-CVE-2026-105326"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"CUPS printing service","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary commands via argument injection in CUPS mailto notifier when email notifications are enabled.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":2.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-88","name":"Improper Neutralization of Argument Delimiters in a Command"}],"description":"An argument injection flaw was found in CUPS. When email notification is configured, the CUPS scheduler accepts printer subscription requests that supply a mailto notify-recipient-uri. The mailto notifier passes the recipient address to the configured sendmail program without ensuring it cannot be interpreted as command-line options. A remote attacker who can reach the CUPS service could supply a crafted recipient value starting with \"-\" to influence sendmail behavior. Successful exploitation depends on the installed mail transfer agent and CUPS network exposure, and may lead to execution of attacker-controlled commands with the privileges of the CUPS service user.","ecosystems":["Red Hat:hummingbird:1"],"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":"Cups: cups: argument injection in mailto notifier via notify-recipient-uri","id":"CVE-2026-105326","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":8,"n_references":6,"next":{"headline":"TallCMS PluginManager ThemeManager.php code injection","id":"CVE-2026-105329"},"packages":[{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.4.19-4.3.hum1"],"introduced":["0"],"last_affected":[],"package":"cups","purl":"pkg:rpm/redhat/cups","source":"RHSA-2026:77638"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.4.19-4.3.hum1"],"introduced":["0"],"last_affected":[],"package":"cups-client","purl":"pkg:rpm/redhat/cups-client","source":"RHSA-2026:77638"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.4.19-4.3.hum1"],"introduced":["0"],"last_affected":[],"package":"cups-devel","purl":"pkg:rpm/redhat/cups-devel","source":"RHSA-2026:77638"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.4.19-4.3.hum1"],"introduced":["0"],"last_affected":[],"package":"cups-filesystem","purl":"pkg:rpm/redhat/cups-filesystem","source":"RHSA-2026:77638"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.4.19-4.3.hum1"],"introduced":["0"],"last_affected":[],"package":"cups-ipptool","purl":"pkg:rpm/redhat/cups-ipptool","source":"RHSA-2026:77638"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.4.19-4.3.hum1"],"introduced":["0"],"last_affected":[],"package":"cups-libs","purl":"pkg:rpm/redhat/cups-libs","source":"RHSA-2026:77638"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.4.19-4.3.hum1"],"introduced":["0"],"last_affected":[],"package":"cups-lpd","purl":"pkg:rpm/redhat/cups-lpd","source":"RHSA-2026:77638"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.4.19-4.3.hum1"],"introduced":["0"],"last_affected":[],"package":"cups-printerapp","purl":"pkg:rpm/redhat/cups-printerapp","source":"RHSA-2026:77638"}],"prev":{"headline":"An HTTP header injection vulnerability was found in the ADM","id":"CVE-2026-105324"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat Hardened Images"],"published":"2026-10-05","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-07","vendors":["Red Hat"]},"summary":"Remote attackers can execute arbitrary commands via argument injection in CUPS mailto notifier when email notifications are enabled.","url":"https://insights.sbomify.com/CVE-2026-105326/"}
