From 1.4.0 until 1.6.4, bookmark restore accepts a client-supplied state_id and joins it into the server-side shiny_bookmarks directory without validating that it is a single safe path segment. An unauthenticated request can use parent-directory segments or an absolute path to make the server open input.json and values.json outside the bookmark store, even when bookmark_store is set to disable. In applications configured with bookmark_store set to server and using ui.input_file(), the restore handler can additionally copy and expose an attacker-selected file from an attacker-selected directory. This issue is fixed in version 1.6.4.","state":0,"publishedAt":"2026-10-09T20:34:39.539+00:00","modifiedAt":"2026-10-13T18:33:20.463+00:00","affected":[{"ecosystem":"Vendor product","name":"py-shiny","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"posit-dev\",\n                    \"product\": \"py-shiny\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.4.0, < 1.6.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"}],"references":["https://github.com/posit-dev/py-shiny/security/advisories/GHSA-47c3-hpmg-7j6p","https://github.com/posit-dev/py-shiny/commit/1d8ecb46cbc9621b7dc8812111d26692e086b376","https://github.com/posit-dev/py-shiny/releases/tag/v1.6.4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-108258","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-108258","identifiers":["CVE-2026-108258"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
