Affected is the function InternalController.TestProxy of the file client-engine-application/f.cs of the component Proxy Validation. Executing a manipulation of the argument host/port can lead to server-side request forgery. The attack may be launched remotely. Upgrading to version 5.2.0 is able to address this issue. It is suggested to upgrade the affected component. The route has been removed and replaced with /general/test-proxy in 5.2.0.","state":0,"publishedAt":"2026-10-26T12:45:07.213+00:00","modifiedAt":"2026-10-26T12:45:07.213+00:00","affected":[{"ecosystem":"Vendor product","name":"Kameleo","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"vendor\": \"n/a\",\n \"product\": \"Kameleo\",\n \"versions\": [\n {\n \"version\": \"5.0.1.0\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.1\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.2\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.3\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.4\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.5\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.6\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.7\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.8\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.9\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.10\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.11\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.12\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.13\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.14\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.15\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.16\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.17\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.18\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.19\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.20\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.21\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.22\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.23\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.24\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.25\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.0.1.26\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"5.2.0\",\n \"status\": \"unaffected\"\n }\n ],\n \"cpes\": [\n \"cpe:2.3:a:kameleo:kameleo:*:*:*:*:*:*:*:*\"\n ],\n \"modules\": [\n \"Proxy Validation\"\n ]\n }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:X","score":5.1,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L/E:X/RL:O/RC:C","score":5.5,"severity":"MEDIUM"},{"system":"CVSS 3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L/E:X/RL:O/RC:C","score":5.5,"severity":"MEDIUM"},{"system":"CVSS 2.0","vector":"AV:N/AC:L/Au:S/C:P/I:P/A:P/E:ND/RL:OF/RC:C","score":6.5,"severity":null}],"references":["https://vuldb.com/vuln/426305","https://vuldb.com/vuln/426305/cti","https://vuldb.com/cve/CVE-2026-116280","https://vuldb.com/submit/1011318","https://drive.google.com/drive/folders/1v9qTuMbrKnJStOeWqS-PDXz1KbmMheQ3?usp=drive_link","https://github.com/kameleo-io/kameleo/releases/tag/5.2.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116280","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116280","identifiers":["CVE-2026-116280"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
