OpenURL() in usersession/userd/launcher.go would alter $XDG_DATA_DIRS to append a path to a directory controlled by the calling snap. A malicious snap could exploit this to bypass intended access restrictions to control how the host system xdg-open script opens the URL and, for example, execute a script shipped with the snap without confinement. This issue did not affect Ubuntu Core systems. Fixed in snapd versions 2.45.1ubuntu0.2, 2.45.1+18.04.2 and 2.45.1+20.04.2.","published_at":"2020-07-29T16:25:26.118000Z","last_modified_at":null,"cvss_v3_score":5.9,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:N/I:H/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://ubuntu.com/USN-4424-1","https://launchpad.net/bugs/1880085"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:13:21.313572Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"canonical","vendor_name":"Canonical","product_slug":"snapd","product_name":"snapd","version_start":"2.45.1","version_start_inclusive":true,"version_end":"2.45.1ubuntu0.2","version_end_inclusive":false,"cpe23_uri":"cve5:canonical:snapd:2.45.1:2.45.1ubuntu0.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://ubuntu.com/USN-4424-1","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://launchpad.net/bugs/1880085","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2020-07-29T16:25:26.118000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:02:06.718090Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:02:06.718090Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:02:06.718090Z","label":"CVSS score revised","source":"cvelistv5"}]}
