From 0.74.0 until 0.78.1, Pi versions with temporary npm or git extension package installs used predictable paths under the operating system temporary directory. On Linux-based multi-user systems, a local attacker who can write to the shared temporary directory could prepare the expected package location before another user runs pi with a temporary extension package source. Pi could then load attacker-controlled extension code in the victim user's process.  This vulnerability is fixed in 0.78.1.","state":0,"publishedAt":"2026-06-23T19:25:04.051+00:00","modifiedAt":"2026-06-24T13:38:04.242+00:00","affected":[{"ecosystem":"Vendor product","name":"pi","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"earendil-works\",\n                    \"product\": \"pi\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.74.0, < 0.78.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","score":7.3,"severity":"HIGH"}],"references":["https://github.com/earendil-works/pi/security/advisories/GHSA-jfgx-wxx8-mp94","https://github.com/earendil-works/pi/pull/5345","https://github.com/earendil-works/pi/commit/a98e087e5d08ea2a536bf73dbb0aebb87c3ef72e","https://github.com/earendil-works/pi/commit/ea3465a8e371a12d0167a06b60f93878e3a3df44","https://github.com/earendil-works/pi/releases/tag/v0.78.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54328","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54328","identifiers":["CVE-2026-54328"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
