The fetched stylesheet was read into memory in full, with no size limit and no read timeout, so a stylesheet URL referencing an attacker-controlled host could be used to exhaust server memory. Upstream fixed this in the commit “Add a size limit to the CSS proxy content processing”, which caps the response at 5 MB, reads it as a stream and applies a read timeout.","categories":["Applications & CMS"],"product":"Webmail","vendor":"Roundcube","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114731","source_modified_at":"2026-10-22T02:12:34.577Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Webmail","vendor":"Roundcube","versions":[{"lessThan":"1.6.20","status":"affected","version":"1.6.0","versionType":"semver"},{"lessThan":"1.7.5","status":"affected","version":"1.7.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114731","source_modified_at":"2026-10-22T02:12:34.577Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Webmail","ecosystem":null},"version":"1.6.20","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114731","source_modified_at":"2026-10-22T02:12:34.577Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Webmail","ecosystem":null},"version":"1.7.5","basis":"first unaffected version stated in the CVE record"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00431,"percentile":0.36356,"score_date":"2026-10-23"},"published_at":"2026-10-22T02:12:34.577Z","modified_at":"2026-10-22T02:12:34.577Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-114731","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-22T02:12:34.577Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-114731","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://bugs.debian.org/1151279","tags":["issue-tracking","third-party-advisory"]},{"source":"CVE List","url":"https://github.com/roundcube/roundcubemail/commit/2c9f6da692fa37cad2aaf85d5b127b583d22b264","tags":["patch"]},{"source":"CVE List","url":"https://roundcube.net/news/2026/10/19/security-updates-1.6.20-and-1.7.5","tags":["vendor-advisory","release-notes"]},{"source":"CVE List","url":"https://github.com/roundcube/roundcubemail/releases/tag/1.7.5","tags":["release-notes","patch"]},{"source":"CVE List","url":"https://github.com/roundcube/roundcubemail/releases/tag/1.6.20","tags":["release-notes","patch"]},{"source":"CVE List","url":"https://github.com/roundcube/roundcubemail/commit/99a5bdd05b01f45493cc0da4c96968eac7668126","tags":["patch"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-22T02:12:34.577Z","content_hash":"962805759db7e18c828a568bfed295f54823cebf53fdf431b09a5a43dd7a352b"}}
