{"id":"CVE-2026-111241","kind":"vulnerability","aliases":["CVE-2026-111241"],"related":[],"title":"Java session bean passivation writes predictable temp files, enabling local code execution","description":"When a non-default stateful session bean passivation strategy is configured, passivated bean state is written to predictably named files in the shared system temporary directory, reusing files that already exist there, and is deserialized on activation. A local attacker who can write to that directory can read passivated session state or supply data that the server deserializes, potentially leading to code execution as the server process. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.","summary":"When a non-default stateful session bean passivation strategy is enabled, passivated bean state is saved to predictably named files in the shared system temporary directory and reused if they already exist.
