Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-48849 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-2026-48849/ (Markdown: https://insights.sbomify.com/CVE-2026-48849/index.md)","id":"CVE-2026-48849","markdown":"https://insights.sbomify.com/CVE-2026-48849/index.md","name":"CVE-2026-48849","record":{"aliases":["DEBIAN-CVE-2026-48849","GHSA-2m7q-4j9m-89vh","UBUNTU-CVE-2026-48849"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Roundcube Webmail","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts via unsanitized subject fields in restored drafts, affecting shared mailboxes in Roundcube Webmail.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In Roundcube Webmail 1.6.x before 1.6.16 and 1.7.x before 1.7.1, an unsanitized subject field in the draft restored value could lead to stored XSS/HTML/CSS injection on shared mailboxes.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-15","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-15T06:43:23Z","kind":"github_poc","ref":"https://github.com/AnandJogawade/CVE-2026-48849-Roundcube-Webmail-Stored-XSS","stars":1,"title":"This repository documents CVE-2026-48849, a Stored Cross-Site Scripting (XSS), HTML Injection, and CSS Injection vulnerability discovered in Roundcube Webmai"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Cross-site scripting in Webmail","id":"CVE-2026-48849","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Use after free in PuTTY","id":"CVE-2026-48850"},"packages":[],"prev":{"headline":"Cross-site scripting in Webmail","id":"CVE-2026-48848"},"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-26","vendors":["Roundcube"]},"summary":"Attackers can inject malicious scripts via unsanitized subject fields in restored drafts, affecting shared mailboxes in Roundcube Webmail.","url":"https://insights.sbomify.com/CVE-2026-48849/"}
