A malicious application can register a ContentProvider returning a _display_name value containing traversal sequences, which is passed unsanitized through FileManager.getDisplayNameFromUri and AttachmentFileHelper.copyFileDirectly, causing automatic file writes to attacker-chosen locations with TickTick's application privileges.","state":0,"publishedAt":"2026-10-19T17:58:54.222+00:00","modifiedAt":"2026-10-22T20:56:29.624+00:00","affected":[{"ecosystem":"Vendor product","name":"TickTick for Android","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"TickTick Limited\",\n                    \"product\": \"TickTick for Android\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"8.2.2.0\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":6.2,"severity":"MEDIUM"}],"references":["https://github.com/actuator/com.ticktick.task/","https://www.vulncheck.com/advisories/ticktick-android-path-traversal-via-sharereceiveactivity"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-11319","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-11319","identifiers":["CVE-2026-11319"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
