Due to the non-committing property of AES-GCM (and other AEAD ciphers such as AES-GCM-SIV or (X)ChaCha20Poly1305) used by the SDKs to encrypt messages, an attacker can craft a unique cyphertext which will decrypt to multiple different results, and becomes especially relevant in a multi-recipient setting. We recommend users update their SDK to 2.0.0 or later.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2020-8897","reference_id":"","reference_type":"","scores":[{"value":"0.00078","scoring_system":"epss","scoring_elements":"0.23284","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00078","scoring_system":"epss","scoring_elements":"0.23478","published_at":"2026-06-12T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2020-8897"},{"reference_url":"https://aws.amazon.com/blogs/security/improved-client-side-encryption-explicit-keyids-and-key-commitment","reference_id":"","reference_type":"","scores":[{"value":"8.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},{"value":"8.6","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://aws.amazon.com/blogs/security/improved-client-side-encryption-explicit-keyids-and-key-commitment"},{"reference_url":"https://aws.amazon.com/blogs/security/improved-client-side-encryption-explicit-keyids-and-key-commitment/","reference_id":"","reference_type":"","scores":[],"url":"https://aws.amazon.com/blogs/security/improved-client-side-encryption-explicit-keyids-and-key-commitment/"},{"reference_url":"https://github.com/google/security-research/security/advisories/GHSA-wqgp-vphw-hphf","reference_id":"","reference_type":"","scores":[{"value":"8.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"8.6","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/google/security-research/security/advisories/GHSA-wqgp-vphw-hphf"},{"reference_url":"https://github.com/pypa/advisory-database/tree/main/vulns/aws-encryption-sdk/PYSEC-2020-261.yaml","reference_id":"","reference_type":"","scores":[{"value":"8.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},{"value":"8.6","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/pypa/advisory-database/tree/main/vulns/aws-encryption-sdk/PYSEC-2020-261.yaml"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2020-8897","reference_id":"","reference_type":"","scores":[{"value":"8.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},{"value":"8.6","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-8897"},{"reference_url":"https://github.com/advisories/GHSA-wqgp-vphw-hphf","reference_id":"GHSA-wqgp-vphw-hphf","reference_type":"","scores":[{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-wqgp-vphw-hphf"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/61485?format=json","purl":"pkg:pypi/aws-encryption-sdk@2.0.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qxgd-z73f-zkh2"},{"vulnerability":"VCID-ysae-xz84-vqhq"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/aws-encryption-sdk@2.0.0"}],"aliases":["CVE-2020-8897","GHSA-wqgp-vphw-hphf","PYSEC-2020-261"],"risk_score":4.0,"exploitability":"0.5","weighted_severity":"8.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-hj1a-4jk7-dkd5"}],"fixing_vulnerabilities":[],"risk_score":"4.0","resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/aws-encryption-sdk@1.3.3"}
