The files published as part of request_store 1.3.2 have 0666 permissions, meaning that they are world-writable, which allows local users to execute arbitrary code. This version was published in 2017, and most production environments do not allow access for local users, so the chances of this being exploited are very low, given that the vast majority of users will have upgraded, and those that have not, if any, are not likely to be exposed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-276"],"references":["https://github.com/steveklabnik/request_store/security/advisories/GHSA-frp2-5qfc-7r8m"],"products":["steveklabnik:request_store"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-43791","score":0.00194,"percentile":0.09141,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-frp2-5qfc-7r8m","url":"https://osv.dev/vulnerability/GHSA-frp2-5qfc-7r8m","summary":"request_store has Incorrect Default Permissions","modified":"2024-08-26T14:12:40Z","packages":[{"ecosystem":"RubyGems","name":"request_store","purl":"pkg:gem/request_store","ranges":[">=1.3.2 <1.4.0"],"fixed":["1.4.0"]}]}],"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).
