## Summary

FlowCI flow-core-x's LocalFileManager component has a path traversal flaw in its file exist, save, read, and remove functions. An attacker who can reach it remotely after logging in with low privileges can reach files outside the intended storage directory, with limited effect on confidentiality, integrity, and availability.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- FlowCI flow-core-x: 1.23.0, 1.23.1, 1.23.2, 1.23.3, 1.23.4, 1.23.5, 1.23.6, 1.23.7, 1.23.8, 1.23.9, 1.23.10, 1.23.11, 1.23.12, 1.23.13, 1.23.14, 1.23.15, 1.23.16, 1.23.17, 1.23.18, 1.23.19, 1.23.20, 1.23.21, 1.23.22, 1.23.23, 1.23.24, 1.23.25, 1.23.26, 1.23.27, 1.23.28, 1.23.29, and 20 more

## Description

A vulnerability was determined in FlowCI flow-core-x up to 1.23.49. This affects the function exist/save/read/remove of the file store/src/main/java/com/flowci/store/LocalFileManager.java of the component LocalFileManager. This manipulation of the argument fileName causes path traversal. It is possible to initiate the attack remotely. A high degree of complexity is needed for the attack. The exploitability is reported as difficult. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
