The application generates absolute URLs (such as those used in password reset emails) using the user-supplied Host header. This allows remote attackers to poison the password reset link sent to a victim,","aliases":[{"alias":"CVE-2026-26747"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-26747","reference_id":"","reference_type":"","scores":[{"value":"0.00081","scoring_system":"epss","scoring_elements":"0.23806","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00081","scoring_system":"epss","scoring_elements":"0.2401","published_at":"2026-06-13T12:55:00Z"},{"value":"0.00081","scoring_system":"epss","scoring_elements":"0.24002","published_at":"2026-06-12T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-26747"},{"reference_url":"https://github.com/hungnqdz/cve-research/blob/main/CVE-2026-26747.md","reference_id":"CVE-2026-26747.md","reference_type":"","scores":[{"value":"9.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:Y/T:P/P:M/B:A/M:M/D:T/2026-02-23T20:36:32Z/"}],"url":"https://github.com/hungnqdz/cve-research/blob/main/CVE-2026-26747.md"},{"reference_url":"https://github.com/monicahq/monica","reference_id":"monica","reference_type":"","scores":[{"value":"9.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:Y/T:P/P:M/B:A/M:M/D:T/2026-02-23T20:36:32Z/"}],"url":"https://github.com/monicahq/monica"}],"weaknesses":[],"exploits":[],"severity_range_score":"9.1 - 9.1","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-5trw-sssh-q7hz"}
