Attackers can authorize the app's client ID with their own Reddit account, then deliver an infinity://localhost redirect containing their code and the constant state, causing the victim's posts, messages, and browsing to occur on the attacker's account.","state":0,"publishedAt":"2026-10-25T11:50:59.942+00:00","modifiedAt":"2026-10-25T11:50:59.942+00:00","affected":[{"ecosystem":"Vendor product","name":"Infinity for Reddit","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Docile-Alligator\",\n                    \"product\": \"Infinity for Reddit\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThanOrEqual\": \"8.3.4\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/Docile-Alligator/Infinity-For-Reddit/issues/1975","https://github.com/Docile-Alligator/Infinity-For-Reddit","https://github.com/Docile-Alligator/Infinity-For-Reddit/blob/v8.3.4/app/src/main/java/ml/docilealligator/infinityforreddit/activities/LoginChromeCustomTabActivity.java#L194-L205","https://github.com/Docile-Alligator/Infinity-For-Reddit/blob/v8.3.4/app/src/main/java/ml/docilealligator/infinityforreddit/utils/APIUtils.java#L43","https://github.com/Docile-Alligator/Infinity-For-Reddit/blob/v8.3.4/app/src/main/AndroidManifest.xml#L75-L92","https://www.vulncheck.com/advisories/infinity-for-reddit-through-8.3.4-oauth-login-csrf-via-loginchromecustomtabactivity"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116072","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116072","identifiers":["CVE-2026-116072"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
