{"cve":"CVE-2025-24015","nvd":{"published":"2025-06-03T23:15:20.633","modified":"2026-06-17T08:57:53.560","status":"Analyzed","description":"Deno is a JavaScript, TypeScript, and WebAssembly runtime. 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.","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","score":7.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-347"],"references":["https://github.com/denoland/deno/commit/0d1beed","https://github.com/denoland/deno/commit/4f27d7cdc02e3edfb9d36275341fb8185d6e99ed","https://github.com/denoland/deno/commit/a4003a5292bd0affefad3ecb24a8732886900f67","https://github.com/denoland/deno/security/advisories/GHSA-2x3r-hwv5-p32x","https://github.com/denoland/deno/security/advisories/GHSA-2x3r-hwv5-p32x"],"products":["deno:deno"],"source":"nvd","synced_at":"2026-10-19T22:02:23.998251710+00:00"},"epss":{"cve":"CVE-2025-24015","score":0.00287,"percentile":0.21224,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-2x3r-hwv5-p32x","url":"https://osv.dev/vulnerability/GHSA-2x3r-hwv5-p32x","summary":"Deno's AES GCM authentication tags are not verified","modified":"2026-09-10T03:50:24.817511634Z","packages":[{"ecosystem":"crates.io","name":"deno","purl":"pkg:cargo/deno","ranges":[">=1.46.0 <2.1.7"],"fixed":["2.1.7"]},{"ecosystem":"crates.io","name":"deno_node","purl":"pkg:cargo/deno_node","ranges":[">=0.102.0 <0.125.0"],"fixed":["0.125.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
