From 1.0.319 until 1.2.14, Backend\\Classes\\Controller::actionExists() accepts public handler-shaped methods as page actions, so a top-level GET request can invoke state-changing backend AJAX handlers without a CSRF token. Because backend routes use Route::any, CSRF validation skips GET, and the default SameSite=Lax session cookie is sent on cross-site navigation, an unauthenticated attacker can induce an authorized backend user to follow a link such as /backend/system/eventlogs/index_onEmptyLog. Affected handlers in the backend, CMS, and system modules can truncate logs, reset settings, alter backend user state, or delete CMS templates, while URL path segments can select a target record. This issue is fixed in version 1.2.14."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"wintercms","product":"winter","versions":[{"version":"\u003e= 1.0.319, \u003c 1.2.14","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:H","baseScore":6.1,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":0.9,"impactScore":5.2}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-352"}]}],"references":[{"url":"https://github.com/wintercms/winter/commit/353b23804dee2acf49fca996c72637040446824f","source":"security-advisories@github.com"},{"url":"https://github.com/wintercms/winter/releases/tag/v1.2.14","source":"security-advisories@github.com"},{"url":"https://github.com/wintercms/winter/security/advisories/GHSA-p2ch-c2c3-4xm5","source":"security-advisories@github.com"}]}}
