{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/63236?format=json","vulnerability_id":"VCID-2v3a-jr55-ybbj","summary":"The 'Copy Image Link' context menu action would copy the final image URL after redirects. By embedding an image that triggered authentication flows - in conjunction with a Content Security Policy that stopped a redirection chain in the middle - the final image URL could be one that contained an authentication token used to takeover a user account.  If a website tricked a user into copy and pasting the image link back to the page, the page would be able to steal the authentication tokens.  This was fixed by making the action return the original URL, before any redirects.","aliases":[{"alias":"CVE-2021-43532"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/1112518?format=json","purl":"pkg:deb/debian/firefox@150.0.3-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@150.0.3-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/584097?format=json","purl":"pkg:deb/debian/firefox@94.0-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@94.0-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/582059?format=json","purl":"pkg:deb/debian/firefox@149.0-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@149.0-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1059611?format=json","purl":"pkg:deb/debian/firefox@149.0.2-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@149.0.2-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1076056?format=json","purl":"pkg:deb/debian/firefox@150.0-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@150.0-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1088670?format=json","purl":"pkg:deb/debian/firefox@150.0.1-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@150.0.1-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1105248?format=json","purl":"pkg:deb/debian/firefox@150.0.2-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@150.0.2-1%3Fdistro=sid"}],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2021-43532","reference_id":"","reference_type":"","scores":[{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.34768","published_at":"2026-05-12T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.34728","published_at":"2026-05-05T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.348","published_at":"2026-05-07T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.34837","published_at":"2026-05-09T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.34742","published_at":"2026-05-11T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.3521","published_at":"2026-04-07T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.35254","published_at":"2026-04-08T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.3528","published_at":"2026-04-09T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.35283","published_at":"2026-04-11T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.35247","published_at":"2026-04-12T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.35223","published_at":"2026-04-13T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.35262","published_at":"2026-04-16T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.35248","published_at":"2026-04-18T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.35198","published_at":"2026-04-21T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.34964","published_at":"2026-04-24T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.34946","published_at":"2026-04-26T12:55:00Z"},{"value":"0.00148","scoring_system":"epss","scoring_elements":"0.34856","published_at":"2026-04-29T12:55:00Z"},{"value":"0.00226","scoring_system":"epss","scoring_elements":"0.45267","published_at":"2026-04-01T12:55:00Z"},{"value":"0.00226","scoring_system":"epss","scoring_elements":"0.45349","published_at":"2026-04-02T12:55:00Z"},{"value":"0.00226","scoring_system":"epss","scoring_elements":"0.45369","published_at":"2026-04-04T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2021-43532"},{"reference_url":"https://www.mozilla.org/en-US/security/advisories/mfsa2021-48","reference_id":"mfsa2021-48","reference_type":"","scores":[{"value":"high","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://www.mozilla.org/en-US/security/advisories/mfsa2021-48"}],"weaknesses":[],"exploits":[],"severity_range_score":"7.0 -
