{"cve":"CVE-2024-38366","nvd":{"published":"2024-07-01T21:15:03.797","modified":"2026-06-17T07:40:00.100","status":"Modified","description":"trunk.cocoapods.org is the authentication server for the CoacoaPods dependency manager. The part of trunk which verifies whether a user has a real email address on signup used a rfc-822 library which executes a shell command to validate the email domain MX records validity. It works via an DNS MX. This lookup could be manipulated to also execute a command on the trunk server, effectively giving root access to the server and the infrastructure. This issue was patched server-side with commit 001cc3a430e75a16307f5fd6cdff1363ad2f40f3 in September 2023. This RCE triggered a full user-session reset, as an attacker could have used this method to write to any Podspec in trunk.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10.0},"cwes":["CWE-74"],"references":["https://blog.cocoapods.org/CocoaPods-Trunk-RCEs-2023","https://evasec.webflow.io/blog/eva-discovered-supply-chain-vulnerabities-in-cocoapods#2-remote-code-execution-on-the-cocoapods-trunk-server","https://github.com/CocoaPods/CocoaPods/security/advisories/GHSA-x2x4-g675-qg7c","https://blog.cocoapods.org/CocoaPods-Trunk-RCEs-2023","https://evasec.webflow.io/blog/eva-discovered-supply-chain-vulnerabities-in-cocoapods#2-remote-code-execution-on-the-cocoapods-trunk-server"],"products":["cocoapods:trunk.cocoapods.org"],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2024-38366","score":0.17786,"percentile":0.97166,"date":"2026-10-31"},"kev":null,"osv":[],"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).
