Prior to 24.05.50 and 25.03.44, plugins/star-rating/api/api.js allows a non-global application administrator to use uploadFeedbackFile to store attacker-controlled active content while trusting the supplied MIME type. plugins/star-rating/frontend/app.js publicly serves the stored content from feedback/preview/ with the attacker-influenced Content-Type, so a global administrator who opens the preview executes the payload in the Countly origin and exposes authenticated session capabilities, including auth_token and csrf_token values. This issue is fixed in versions 24.05.50 and 25.03.44.","state":0,"publishedAt":"2026-10-16T16:04:45.868+00:00","modifiedAt":"2026-10-21T02:24:31.741+00:00","affected":[{"ecosystem":"Vendor product","name":"countly-server","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Countly\",\n                    \"product\": \"countly-server\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 24.05.50\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 25.03, < 25.03.44\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","score":9,"severity":"CRITICAL"}],"references":["https://github.com/Countly/countly-server/security/advisories/GHSA-jqp4-p86c-phxc","https://github.com/Countly/countly-server/commit/ae899f37bc6d70c1b44859756ce80a204ae72631","https://github.com/Countly/countly-server/commit/fcb16c808c0fdb6dc99fe9c66de7fc560b3a9c41","https://github.com/Countly/countly-server/releases/tag/24.05.50","https://github.com/Countly/countly-server/releases/tag/25.03.44"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-44977","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-44977","identifiers":["CVE-2026-44977"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
