CVE-2026-123508— Vikunja before 2.7.1 Supply Chain Risk via Unpinned xgo Release Toolchain

Quick assessment

Affected

go-vikunja vikunja

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

2.7.1 版本之前的 Vikunja 在其基于 Mage 的发布目标中存在供应链漏洞：这些目标通过可变的"latest"标签来获取 xgo 模块和 Docker 镜像。如果攻击者攻破了上游的 xgo 模块、镜像或镜像仓库，他们便能在后续构建的、带有有效签名的发布二进制文件中注入恶意代码。
