{"id":"CVE-2020-8908","url":"https://www.cyber-defence.io/tools/cve/CVE-2020-8908","generatedAt":"2026-10-27T21:15:25.869Z","title":"A temp directory creation vulnerability exists in all versions of Guava, allowing an attacker with access to the machine to potentially access data in a temporary directory created by the Guava API com.google.common.io.Files.createTempDir().","description":"A temp directory creation vulnerability exists in all versions of Guava, allowing an attacker with access to the machine to potentially access data in a temporary directory created by the Guava API com.google.common.io.Files.createTempDir(). By default, on unix-like systems, the created directory is world-readable (readable by an attacker with access to the system). The method in question has been marked @Deprecated in versions 30.0 and later and should not be used. For Android developers, we recommend choosing a temporary directory API provided by Android, such as context.getCacheDir(). For other Java developers, we recommend migrating to the Java 7 API java.nio.file.Files.createTempDirectory() which explicitly configures permissions of 700, or configuring the Java runtime's java.io.tmpdir system property to point to a location whose permissions are appropriately configured.","published":"2020-12-10T23:15:14.000Z","lastModified":"2026-06-17T03:27:10.000Z","status":"Modified","sourceIdentifier":"cve-coordination@google.com","cvss":{"version":"3.1","score":3.3,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-378","CWE-732"],"affected":["google/guava","quarkus/quarkus","oracle/commerce guided search","oracle/communications cloud native core network slice selection function","oracle/communications pricing design center","oracle/data integrator","oracle/nosql database","oracle/peoplesoft enterprise peopletools","oracle/retail customer management and segmentation foundation","oracle/weblogic server","oracle/communications cloud native core network repository function","oracle/primavera unifier","netapp/active iq unified manager"],"epss":{"score":0.00924,"percentile":0.6015,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.92%).
