FlowDroid versions prior to 2.9.0 contained an XML external entity (XXE) vulnerability that allowed an attacker who had control over the source/sink definition file in XML format to read files from external locations. In order for this to occur, the XML-based format for sources and sinks had to be used and the attacker had to able control the source/sink definition file. The vulnerability was patched in version 2.9.0. As a workaround, do not allow untrusted entities to control the source/sink definition file.","severity":{"version":"3.1","score":5.3,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00643,"percentile":0.51166,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-611"],"published":"2021-07-12T23:00:11Z","modified":"2026-06-17T03:53:33Z","products":[{"vendor":"flowdroid_project","product":"flowdroid"},{"vendor":"secure-software-engineering","product":"flowdroid"}],"references":[{"url":"https://github.com/secure-software-engineering/FlowDroid/security/advisories/GHSA-39r7-275f-rvgw","tags":["x_refsource_CONFIRM","x_transferred","Third Party Advisory"]}],"sources":{"cve":[{"id":"CVE-2021-32754","title":"Improper Restriction of XML External Entity Reference in de.tud.sse","description":"FlowDroid is a data flow analysis tool.
