CVE-2026-123510 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 1.0 (low) and affects vikunja; fixed in 2.7.1.

## Summary

Vikunja, a task management application, before version 2.7.1 can load plugins from and write logs to the startup working directory instead of its configured root path. A local attacker with low-privilege access who can write to that directory could plant a malicious plugin that loads when plugins are enabled, or read misplaced logs, including the audit log, and this requires user interaction and an unusual setup.

## Description

Vikunja before 2.7.1 fails to re-anchor PluginsDir and LogPath to service.rootpath, allowing plugins to load from and logs to be written in the startup working directory. Local attackers able to write to that directory can plant plugins loaded into the server when plugins are enabled, or read misplaced logs including audit.log.
