That value is embedded\ndirectly into the final ICS line by the normal serializer, so a\npayload containing CRLF can terminate the original property and\ncreate a new ICS property or component. (It looks like you can\ninject via url, source, image, organizer, attach, attendee,\nconference, tzurl because of this)\n\nRelevant code:\n- `lib/icalendar/values/uri.rb:16`\n\n### Impact\n\nApplications that generate `.ics` files from partially untrusted\nmetadata are impacted. As a result, downstream calendar clients\nor importers may process attacker-supplied content as if it were\nlegitimate event data, such as added attendees, modified URLs,\nalarms, or other calendar fields.\n\n## Fix\n\nReject raw CR and LF characters in `URI`-typed values before\nserialization, or escape/encode them so they cannot terminate\nthe current ICS content line.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2026-33635", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.0005", "scoring_system": "epss", "scoring_elements": "0.16051", "published_at": "2026-06-06T12:55:00Z" }, { "value": "0.0005", "scoring_system": "epss", "scoring_elements": "0.1592", "published_at": "2026-06-08T12:55:00Z" }, { "value": "0.0005", "scoring_system": "epss", "scoring_elements": "0.16007", "published_at": "2026-06-07T12:55:00Z" }, { "value": "0.0005", "scoring_system": "epss", "scoring_elements": "0.16061", "published_at": "2026-06-05T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2026-33635" }, { "reference_url": "https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2026-33635", "reference_id": "", "reference_type": "", "scores": [], "url": "https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2026-33635" }, { "reference_url": "https://github.com/icalendar/icalendar", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/icalendar/icalendar" }, { "reference_url": "https://github.com/icalendar/icalendar/commit/b8d23b490363ee5fffaec1d269a8618a912ca265", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-30T11:33:37Z/" } ], "url": "https://github.com/icalendar/icalendar/commit/b8d23b490363ee5fffaec1d269a8618a912ca265" }, { "reference_url": "https://github.com/icalendar/icalendar/security/advisories/GHSA-pv9c-9mfh-hvxq", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.3", "scoring_system": "cvssv3", "scoring_elements": "" }, { "value": "4.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-30T11:33:37Z/" } ], "url": "https://github.com/icalendar/icalendar/security/advisories/GHSA-pv9c-9mfh-hvxq" }, { "reference_url": "https://github.com/rubysec/ruby-advisory-db/blob/master/gems/icalendar/CVE-2026-33635.yml", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-30T11:33:37Z/" } ], "url": "https://github.com/rubysec/ruby-advisory-db/blob/master/gems/icalendar/CVE-2026-33635.yml" }, { "reference_url": "https://nvd.nist.gov/vuln/detail/CVE-2026-33635", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-33635" }, { "reference_url": "https://github.com/advisories/GHSA-pv9c-9mfh-hvxq", "reference_id": "GHSA-pv9c-9mfh-hvxq", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" } ], "url": "https://github.com/advisories/GHSA-pv9c-9mfh-hvxq" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/113241?format=api", "purl": "pkg:gem/icalendar@2.12.2", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:gem/icalendar@2.12.2" } ], "aliases": [ "CVE-2026-33635", "GHSA-pv9c-9mfh-hvxq" ], "risk_score": 3.1, "exploitability": "0.5", "weighted_severity": "6.2", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-ge52-te2z-17gn" } ], "fixing_vulnerabilities": [], "risk_score": "3.1", "resource_url": "http://public2.vulnerablecode.io/packages/pkg:gem/icalendar@2.10.1" }
