In @podium/layout prior to version 4.6.110 and @podium/proxy prior to version 4.2.74, an attacker using the `Trailer` header as part of the request against proxy endpoints has the ability to take down the server. All Podium layouts that include podlets with proxy endpoints are affected. `@podium/layout`, which is the main way developers/users are vulnerable to this exploit, has been patched in version `4.6.110`. All earlier versions are vulnerable.`@podium/proxy`, which is the source of the vulnerability and is used by `@podium/layout` has been patched in version `4.2.74`. All earlier versions are vulnerable. It is not easily possible to work around this issue without upgrading.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-248"],"references":["https://github.com/podium-lib/layout/commit/fe43e655432b0a5f07b6475f67babcc2588fb039","https://github.com/podium-lib/layout/releases/tag/v4.6.110","https://github.com/podium-lib/proxy/commit/9698a40df081217ce142d4de71f929baaa339cdf","https://github.com/podium-lib/proxy/releases/tag/v4.2.74","https://github.com/podium-lib/proxy/security/advisories/GHSA-3hjg-vc7r-rcrw"],"products":["finn:podium_layout","finn:podium_proxy"],"source":"nvd","synced_at":"2026-10-19T21:29:06.454770966+00:00"},"epss":{"cve":"CVE-2022-24822","score":0.01659,"percentile":0.76649,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3hjg-vc7r-rcrw","url":"https://osv.dev/vulnerability/GHSA-3hjg-vc7r-rcrw","summary":"Denial of Service vulnerability in @podium/layout and @podium/proxy","modified":"2023-11-08T04:08:37.756263Z","packages":[{"ecosystem":"npm","name":"@podium/layout","purl":"pkg:npm/%40podium/layout","ranges":["<4.6.110"],"fixed":["4.6.110"]},{"ecosystem":"npm","name":"@podium/proxy","purl":"pkg:npm/%40podium/proxy","ranges":["<4.2.74"],"fixed":["4.2.74"]}]}],"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).
