# CVE-2025-14306: Robocode vulnerable to Directory Traversal in recursivelyDelete Method

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.1% , percentile 65: FIRST’s model estimates a 1.1% chance of exploitation activity in the next 30 days, higher than 65% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes net.sf.robocode:robocode.core (Maven) < 1.9.5.6, fixed in 1.9.5.6 . Check your lockfile, including transitive dependencies.

## What it is

A directory traversal vulnerability exists in the CacheCleaner component of Robocode version 1.9.3.6. The recursivelyDelete method fails to properly sanitize file paths, allowing attackers to traverse directories and delete arbitrary files on the system. This vulnerability can be exploited by submitting specially crafted inputs that manipulate the file path, leading to potential unauthorized file deletions. https://robo-code.blogspot.com/

## Affected packages

- Maven `net.sf.robocode:robocode.core` < 1.9.5.6 → fixed: 1.9.5.6

## Affected products (CVE record)

- Robocode Project Robocode: 1.9.3.6

## Severity

- GovTech CSG CVSS 4.0: 10 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/AU:Y/R:U/V:D/RE:M/U:Red`
- GitHub CVSS 4.0: 10.0 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/AU:Y/R:U/V:D/RE:M/U:Red`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.07% probability of exploitation activity in the next 30 days; percentile 65.
