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-2026-48847 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-2026-48847/ (Markdown: https://insights.sbomify.com/CVE-2026-48847/index.md)","id":"CVE-2026-48847","markdown":"https://insights.sbomify.com/CVE-2026-48847/index.md","name":"CVE-2026-48847","record":{"aliases":["DEBIAN-CVE-2026-48847","GHSA-9vwp-h229-h4cm","UBUNTU-CVE-2026-48847"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Roundcube Webmail","requires_auth":"none","summary":"Attackers can delete arbitrary files pre-authentication by poisoning Redis or Memcache sessions, requiring specific cache configurations.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"}],"description":"Roundcube Webmail 1.6.x before 1.6.16, and 1.7.x before 1.7.1 allows pre-authentication arbitrary file deletion via redis/memcache session poisoning bypass.","ecosystems":[],"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":"Other in Webmail","id":"CVE-2026-48847","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Cross-site scripting in Webmail","id":"CVE-2026-48848"},"packages":[],"prev":{"headline":"Security feature bypass in Webmail","id":"CVE-2026-48846"},"products":["Webmail"],"published":"2026-05-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-05-26","vendors":["Roundcube"]},"summary":"Attackers can delete arbitrary files pre-authentication by poisoning Redis or Memcache sessions, requiring specific cache configurations.","url":"https://insights.sbomify.com/CVE-2026-48847/"}
