{"id":"CVE-2026-114376","kind":"vulnerability","aliases":["CVE-2026-114376"],"related":[],"title":"wiki-go: path traversal in editor API lets remote users reach files","description":"A weakness has been identified in leomoon-studios wiki-go up to 1.9.1. Affected by this vulnerability is the function SaveHandler/SourceHandler of the file internal/handlers/editor.go of the component API. Executing a manipulation can lead to path traversal. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 1.9.2 addresses this issue. This patch is called 94f7e73ef8df7c58091d72d77a5e26e9fdad98b8. Upgrading the affected component is advised.","summary":"wiki-go, a Go wiki application from leomoon-studios, has a path traversal flaw in its editor save and source handlers in internal/handlers/editor.go.
