{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/81321?format=json","vulnerability_id":"VCID-rrpk-6zgj-dkb6","summary":"Authorization Bypass Through User-Controlled Key vulnerability in phenixdigital phoenix_storybook allows cross-session PubSub topic injection via a URL query parameter.\n\n'Elixir.PhoenixStorybook.Story.ComponentIframeLive':handle_params/3 in lib/phoenix_storybook/live/story/component_iframe_live.ex reads a PubSub topic directly from params[\"topic\"] and broadcasts {:component_iframe_pid, self()} on it with no check that the topic belongs to the requesting session. The shared PhoenixStorybook.PubSub is used to coordinate playground LiveViews with their iframes: a playground subscribes to a session-specific topic and uses the received iframe pid to direct subsequent control messages (variation state, theme switches, extra-assign payloads) via send/2. Because the iframe trusts the query parameter, an attacker who loads /storybook/iframe/<story>?topic=<victim_topic> causes their iframe process pid to be announced on the victim's topic. The victim's playground then addresses its private messages to the attacker's iframe process.\n\nThis issue affects phoenix_storybook from 0.4.0 before 1.1.0.","aliases":[{"alias":"CVE-2026-47068"},{"alias":"GHSA-mrhx-6pw9-q5fh"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/375314?format=json","purl":"pkg:hex/phoenix_storybook@1.1.0","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:hex/phoenix_storybook@1.1.0"}],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-47068","reference_id":"","reference_type":"","scores":[{"value":"0.00054","scoring_system":"epss","scoring_elements":"0.17256","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-47068"},{"reference_url":"https://github.com/phenixdigital/phoenix_storybook","reference_id":"","reference_type":"","scores":[{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/phenixdigital/phoenix_storybook"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47068","reference_id":"","reference_type":"","scores":[{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47068"},{"reference_url":"https://github.com/phenixdigital/phoenix_storybook/commit/6ee03f1c738d4436dde1b066cf65c80663d489f5","reference_id":"6ee03f1c738d4436dde1b066cf65c80663d489f5","reference_type":"","scores":[{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:Y/T:P/P:M/B:A/M:M/D:T/2026-05-21T13:59:23Z/"}],"url":"https://github.com/phenixdigital/phoenix_storybook/commit/6ee03f1c738d4436dde1b066cf65c80663d489f5"},{"reference_url":"https://nvd.nist.gov/vuln/search/results?adv_search=true&isCpeNameSearch=true&query=cpe:2.3:a:phenixdigital:phoenix_storybook:*:*:*:*:*:*:*:*","reference_id":"cpe:2.3:a:phenixdigital:phoenix_storybook:*:*:*:*:*:*:*:*","reference_type":"","scores":[],"url":"https://nvd.nist.gov/vuln/search/results?adv_search=true&isCpeNameSearch=true&query=cpe:2.3:a:phenixdigital:phoenix_storybook:*:*:*:*:*:*:*:*"},{"reference_url":"https://cna.erlef.org/cves/CVE-2026-47068.html","reference_id":"CVE-2026-47068.html","reference_type":"","scores":[{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:Y/T:P/P:M/B:A/M:M/D:T/2026-05-21T13:59:23Z/"}],"url":"https://cna.erlef.org/cves/CVE-2026-47068.html"},{"reference_url":"https://osv.dev/vulnerability/EEF-CVE-2026-47068","reference_id":"EEF-CVE-2026-47068","reference_type":"","scores":[{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:Y/T:P/P:M/B:A/M:M/D:T/2026-05-21T13:59:23Z/"}],"url":"https://osv.dev/vulnerability/EEF-CVE-2026-47068"},{"reference_url":"https://github.com/phenixdigital/phoenix_storybook/security/advisories/GHSA-mrhx-6pw9-q5fh","reference_id":"GHSA-mrhx-6pw9-q5fh","reference_type":"","scores":[{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:Y/T:P/P:M/B:A/M:M/D:T/2026-05-21T13:59:23Z/"}],"url":"https://github.com/phenixdigital/phoenix_storybook/security/advisories/GHSA-mrhx-6pw9-q5fh"}],"weaknesses":[{"cwe_id":639,"name":"Authorization Bypass Through User-Controlled Key","description":"The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data."}],"exploits":[],"severity_range_score":"0.1 - 3","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-rrpk-6zgj-dkb6"}
