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-2026-48842 in the wild and no public exploit code.\n\nAffected product: Roundcube Webmail. 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-2026-48842/ (Markdown: https://insights.sbomify.com/CVE-2026-48842/index.md)","id":"CVE-2026-48842","markdown":"https://insights.sbomify.com/CVE-2026-48842/index.md","name":"CVE-2026-48842","record":{"aliases":["DEBIAN-CVE-2026-48842","GHSA-vc2v-cxrw-6g4p","UBUNTU-CVE-2026-48842"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Roundcube Webmail","requires_auth":"none","summary":"Attackers can perform pre-authentication SQL injection in Roundcube Webmail via the virtuser_query plugin, potentially accessing or modifying database contents.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"Roundcube Webmail 1.6.x before 1.6.16 and 1.7.x before 1.7.1 has Pre-authentication SQL injection in the virtuser_query plugin via a preg_replace() backslash escape bypass.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-25","github_poc":3,"max_poc_stars":2,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-27T11:26:19Z","kind":"github_poc","ref":"https://github.com/4minx/CVE-2026-48842","stars":2,"title":"CVE-2026-48842 PoC — Roundcube virtuser_query pre-auth SQLi"},{"date":"2026-09-25T05:59:39Z","kind":"github_poc","ref":"https://github.com/murrez/CVE-2026-48842","stars":1,"title":"Roundcube virtuser_query pre-auth SQLi (CVE-2026-48842).
