{"schema":"threatline.record/2","record":{"id":"CVE-2026-44977","aliases":["GHSA-jqp4-p86c-phxc"],"summary":"countly-server: Stored XSS in feedback upload enables app-admin to compromise global admin session context","details":"countly-server is the server-side part of Countly, a product analytics solution. 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.","categories":["Unclassified"],"product":"countly-server","vendor":"Countly","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-44977","source_modified_at":"2026-10-21T02:24:31.741Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"countly-server","vendor":"Countly","versions":[{"version":"< 24.05.50","status":"affected"},{"version":">= 25.03, < 25.03.44","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":9,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00343,"percentile":0.26644,"score_date":"2026-10-23"},"published_at":"2026-10-16T16:04:45.868Z","modified_at":"2026-10-21T02:24:31.741Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-44977","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T02:24:31.741Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-44977","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Countly/countly-server/security/advisories/GHSA-jqp4-p86c-phxc","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/Countly/countly-server/commit/ae899f37bc6d70c1b44859756ce80a204ae72631","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Countly/countly-server/commit/fcb16c808c0fdb6dc99fe9c66de7fc560b3a9c41","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Countly/countly-server/releases/tag/24.05.50","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Countly/countly-server/releases/tag/25.03.44","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-21T02:24:09.405721Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-21T02:24:31.741Z","content_hash":"4359f1087d44058a89c82feab2be028f4ebe8b5555fb0edb25b18f0b53bb81df"}}
