{"id":"CVE-2026-111664","summary":"Safing Portmaster before 2.2.5 Unauthenticated Forced Downgrade via /api/v1/updates/from-url","details":"Safing Portmaster before 2.2.5 contains a missing authorization vulnerability that allows unprivileged local processes to force updates by calling the POST /api/v1/updates/from-url endpoint registered with api.PermitAnyone. Attackers can supply an attacker-controlled index URL that bypasses version checks and auto-apply settings, installing older Safing-signed releases carrying previously fixed vulnerabilities.","modified":"2026-10-17T02:48:44.923210492Z","published":"2026-10-16T17:39:27.588Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-306"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111664.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111664.json"},{"type":"PACKAGE","url":"https://github.com/safing/portmaster"},{"type":"ARTICLE","url":"https://github.com/safing/portmaster/blob/v2.2.3/service/core/api.go#L145-L159"},{"type":"FIX","url":"https://github.com/safing/portmaster/commit/f943e1eaf98f45bc48490bf288e1d63c04929ae0"},{"type":"REPORT","url":"https://github.com/safing/portmaster/issues/2292"},{"type":"ADVISORY","url":"https://github.com/safing/portmaster/releases/tag/v2.2.5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111664"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/safing-portmaster-before-2.2.5-unauthenticated-forced-downgrade-via-api-v1-updates-from-url"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/safing/portmaster","events":[{"introduced":"0"},{"fixed":"67b684cd0c743a4f880f1a7a500bb43c8f3e7da8"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"2.2.5"}]}}],"versions":["v2.2.1","v2.1.18","v2.1.7","v2.0.25","v2.0.23","v2.0.22","v2.0.21","v2.0.20","v1.6.24","v1.6.23","v1.6.22","v1.6.21","v1.6.20","v1.6.19","v1.6.18","v1.6.17","v1.6.16","v1.6.15","v1.6.14","v1.6.13","v1.6.12","v1.6.11","v1.6.10","v1.6.9","v1.6.8","v1.6.7","v1.6.6","v1.6.5","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.1","v1.5.0","v1.4.11","v1.4.10","v1.4.9","v1.4.8","v1.4.7","v1.4.6","v1.4.6-prep2","v1.4.5","v1.4.4","v1.4.3","v1.4.2","v1.4.1","v1.4.0","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.0","v1.1.0","v1.0.14","v1.0.13","v1.0.12","v1.0.11","v1.0.10","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v0.9.11","v0.9.10","v0.9.9","v0.9.8","v0.9.7","v0.9.6","v0.9.5","v0.9.4","v0.9.3","v0.9.2","v0.9.1","v0.9.1-interdep","v0.9.0","v0.8.14-interdep","v0.8.13","v0.8.12","v0.8.11","v0.8.10","v0.8.9","v0.8.9-interdep","v0.8.8","v0.8.7","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.21","v0.7.20","v0.7.19","v0.7.18","v0.7.17","v0.7.16","v0.7.15","v0.7.14","v0.7.13","v0.7.12","v0.7.11","v0.7.10","v0.7.9","v0.7.8","v0.7.7","v0.7.6","v0.7.5","v0.7.4","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.22","v0.6.21","v0.6.20","v0.6.19","v0.6.18","v0.6.17-beta","v0.6.16","v0.6.15","v0.6.14","v0.6.13","v0.6.12","v0.6.11","v0.6.10","v0.6.9","v0.6.8","v0.6.7","v0.6.6","v0.6.5","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.17","v0.4.18","v0.4.16","v0.4.15","v0.4.14","v0.4.13","v0.4.12","v0.4.11","v0.4.10","v0.4.9-0.3.5","v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.2.5","v0.2.3","v0.2.2","v0.2.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111664.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
