It is possible to make any HTTP/HTTPS request to any website in installer functionality. Due to such vulnerability it is possible to for example scan local network, call local services and its functions, conduct a DoS attack, and/or disclose a server's real IP if it's behind a reverse proxy. It is also possible to exhaust server resources by sending plethora of such requests. As of time of publication, no patched releases are available."}], "lastModified": "2025-09-24T13:30:22.057", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:instantcms:instantcms:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "141C4282-DD71-4F2D-B8B2-9D74B055BDC8", "versionEndIncluding": "2.17.3"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
