{"id":"CVE-2026-41322","aliases":["GHSA-c57f-mm3j-27q9"],"url":"https://o3.security/vulnerability/CVE-2026-41322","summary":"@astrojs/node: Cache Poisoning due to incorrect error handling when if-match header is malformed","details":"@astrojs/node allows Astro to deploy your SSR site to Node targets. Prior to 10.0.5, requesting a static js/css resources from _astro path with an incorrect/malformed if-match header returns a 500 error with a one year cache lifetime instead of 412 in some cases. This has the effect that all subsequent requests to that file, regardless of if-match header will be served a 5xx error instead of the file until the cache expires. This vulnerability is fixed in 10.0.5.","published":"2026-04-24T17:08:13.080Z","modified":"2026-08-07T11:31:02.044937835Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@astrojs/node","fixedVersion":"10.0.5"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41322.json"},{"type":"ADVISORY","url":"https://github.com/withastro/astro/security/advisories/GHSA-c57f-mm3j-27q9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41322"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:02.044937835Z"}}
