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.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","cwes":["CWE-352"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit","tags":[]},{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit/blob/v8.3.4/app/src/main/AndroidManifest.xml#L75-L92","tags":[]},{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit/blob/v8.3.4/app/src/main/java/ml/docilealligator/infinityforreddit/activities/LoginChromeCustomTabActivity.java#L194-L205","tags":[]},{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit/blob/v8.3.4/app/src/main/java/ml/docilealligator/infinityforreddit/utils/APIUtils.java#L43","tags":[]},{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit/issues/1975","tags":[]},{"url":"https://www.vulncheck.com/advisories/infinity-for-reddit-through-8.3.4-oauth-login-csrf-via-loginchromecustomtabactivity","tags":[]}],"exploitRefs":[{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit","tags":[]},{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit/blob/v8.3.4/app/src/main/AndroidManifest.xml#L75-L92","tags":[]},{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit/blob/v8.3.4/app/src/main/java/ml/docilealligator/infinityforreddit/activities/LoginChromeCustomTabActivity.java#L194-L205","tags":[]},{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit/blob/v8.3.4/app/src/main/java/ml/docilealligator/infinityforreddit/utils/APIUtils.java#L43","tags":[]},{"url":"https://github.com/Docile-Alligator/Infinity-For-Reddit/issues/1975","tags":[]}],"hasPoc":true,"ai":null}
