Versions 1.46.0 through 2.1.6 have an issue that affects AES-256-GCM and AES-128-GCM in Deno in which the authentication tag is not being validated. This means tampered ciphertexts or incorrect keys might not be detected, which breaks the guarantees expected from AES-GCM. Older versions of Deno correctly threw errors in such cases, as does Node.js. Without authentication tag verification, AES-GCM degrades to essentially CTR mode, removing integrity protection. Authenticated data set with set_aad is also affected, as it is incorporated into the GCM hash (ghash) but this too is not validated, rendering AAD checks ineffective. Version 2.1.7 includes a patch that addresses this issue.","published_at":"2025-06-03T22:48:52.906000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":7.7,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:P","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-347"],"nvd_references":["https://github.com/denoland/deno/security/advisories/GHSA-2x3r-hwv5-p32x","https://github.com/denoland/deno/commit/0d1beed","https://github.com/denoland/deno/commit/4f27d7cdc02e3edfb9d36275341fb8185d6e99ed","https://github.com/denoland/deno/commit/a4003a5292bd0affefad3ecb24a8732886900f67"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:25:54.831587Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"},{"metric":"E","name":"E","value":"P","value_label":"Physical"}]},"affected":[{"vendor_slug":"denoland","vendor_name":"denoland","product_slug":"deno","product_name":"deno","version_start":">= 1.46.0, < 2.1.7","version_start_inclusive":true,"version_end":">= 1.46.0, < 2.1.7","version_end_inclusive":true,"cpe23_uri":"cve5:denoland:deno:>= 1.46.0, < 2.1.7:>= 1.46.0, < 2.1.7"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/denoland/deno/security/advisories/GHSA-2x3r-hwv5-p32x","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/denoland/deno/commit/0d1beed","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/denoland/deno/commit/4f27d7cdc02e3edfb9d36275341fb8185d6e99ed","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/denoland/deno/commit/a4003a5292bd0affefad3ecb24a8732886900f67","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2025-06-03T22:48:52.906000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:43:42.273974Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:43:42.273974Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:43:42.273974Z","label":"CVSS score revised","source":"cvelistv5"}]}
