CVE-2026-55190

6.5 medium Deferred
NVD · CVE.org

Event Schedule is an open-source platform to share events, sell tickets and bring communities together. In versions 1.0.0 and prior, App\Utils\UrlUtils::isUrlSafe() is the SSRF guard applied to user-supplied import URLs. It can be bypassed two ways, both reaching internal/localhost services when the URL is later fetched by ImportCuratorEvents (Http::get($url) then the response body is parsed and imported as events, and file_get_contents($ogImage)). At time of publication, there are no publicly available patches.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
