Prior to version 4.11.7, Cache Middleware contains an information disclosure vulnerability caused by improper handling of HTTP cache control directives. The middleware does not respect standard cache control headers such as `Cache-Control: private` or `Cache-Control: no-store`, which may result in private or authenticated responses being cached and subsequently exposed to unauthorized users. Version 4.11.7 has a patch for the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-524","CWE-613"],"references":["https://github.com/honojs/hono/commit/12c511745b3f1e7a3f863a23ce5f921c7fa805d1","https://github.com/honojs/hono/releases/tag/v4.11.7","https://github.com/honojs/hono/security/advisories/GHSA-6wqw-2p9w-4vw4"],"products":["hono:hono"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-24472","score":0.00522,"percentile":0.44293,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-6wqw-2p9w-4vw4","url":"https://osv.dev/vulnerability/GHSA-6wqw-2p9w-4vw4","summary":"Hono cache middleware ignores \"Cache-Control: private\" leading to Web Cache Deception","modified":"2026-09-10T03:50:32.740573819Z","packages":[{"ecosystem":"npm","name":"hono","purl":"pkg:npm/hono","ranges":["<4.11.7"],"fixed":["4.11.7"]}]}],"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).
