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-2026-48846 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-2026-48846/ (Markdown: https://insights.sbomify.com/CVE-2026-48846/index.md)","id":"CVE-2026-48846","markdown":"https://insights.sbomify.com/CVE-2026-48846/index.md","name":"CVE-2026-48846","record":{"aliases":["DEBIAN-CVE-2026-48846","GHSA-xx87-33v7-6x23","UBUNTU-CVE-2026-48846"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Roundcube Webmail","requires_auth":"none","summary":"Attackers can bypass remote image blocking in Roundcube Webmail via crafted CSS, leading to information disclosure or access-control bypass.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"}],"description":"In Roundcube Webmail 1.6.x before 1.6.16 and 1.7.x before 1.7.1, the remote image blocking feature can be bypassed via a crafted CSS var() value in an e-mail message, which may lead to information disclosure or access-control 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":"Security feature bypass in Webmail","id":"CVE-2026-48846","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Other in Webmail","id":"CVE-2026-48847"},"packages":[],"prev":{"headline":"Information disclosure in Webmail","id":"CVE-2026-48845"},"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-26","vendors":["Roundcube"]},"summary":"Attackers can bypass remote image blocking in Roundcube Webmail via crafted CSS, leading to information disclosure or access-control bypass.","url":"https://insights.sbomify.com/CVE-2026-48846/"}
