{"cve":"CVE-2025-3931","nvd":{"published":"2025-05-14T12:15:19.493","modified":"2026-06-17T09:20:56.967","status":"Deferred","description":"A flaw was found in Yggdrasil, which acts as a system broker, allowing the processes to communicate to other children's \"worker\" processes through the DBus component. Yggdrasil creates a DBus method to dispatch messages to workers. However, it misses authentication and authorization checks, allowing every system user to call it. One available Yggdrasil worker acts as a package manager with capabilities to create and enable new repositories and install or remove packages. \n\nThis flaw allows an attacker with access to the system to leverage the lack of authentication on the dispatch message to force the Yggdrasil worker to install arbitrary RPM packages. This issue results in local privilege escalation, enabling the attacker to access and modify sensitive system data.","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-280"],"references":["https://access.redhat.com/errata/RHSA-2025:7592","https://access.redhat.com/security/cve/CVE-2025-3931","https://bugzilla.redhat.com/show_bug.cgi?id=2362345","https://github.com/RedHatInsights/yggdrasil/pull/336"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2025-3931","score":0.00181,"percentile":0.07683,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rpg2-jvhp-h354","url":"https://osv.dev/vulnerability/GHSA-rpg2-jvhp-h354","summary":"Yggdrasil Vulnerable to Local Privilege Escalation","modified":"2025-07-28T13:04:18Z","packages":[{"ecosystem":"Go","name":"github.com/redhatinsights/yggdrasil","purl":"pkg:golang/github.com/redhatinsights/yggdrasil","ranges":["<=0.4.6"],"fixed":[]}]},{"id":"GO-2025-3688","url":"https://osv.dev/vulnerability/GO-2025-3688","summary":"Yggdrasil Vulnerable to Local Privilege Escalation in github.com/redhatinsights/yggdrasil","modified":"2026-03-03T04:56:35.489137Z","packages":[{"ecosystem":"Go","name":"github.com/redhatinsights/yggdrasil","purl":"pkg:golang/github.com/redhatinsights/yggdrasil","ranges":["all versions"],"fixed":[]}]}],"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).
