Details

It was discovered that Robocode could be tricked into making network
requests to attacker-controlled systems. An attacker could possibly use
this issue to cause external service interaction, resulting in
information disclosure. This issue only affected Ubuntu 16.04 LTS and
Ubuntu 18.04 LTS. (CVE-2019-10648)

Lim Sim Yee discovered that Robocode did not properly validate file
paths in the CacheCleaner component. An attacker could possibly use this
issue to delete arbitrary files. (CVE-2025-14306)

Lim Sim Yee discovered that Robocode did not securely create temporary
files in the AutoExtract component. An attacker could possibly use this
issue to manipulate temporary files, resulting in arbitrary code
execution. (CVE-2025-14307)
