### Official description

DataEase is an open source data visualization and analysis tool. Prior to 2.10.23, DataEase template saves call TemplateManageService#save, StaticResourceServer#saveFilesToServe, and the /de2api/templateManage/save endpoint with attacker-controlled staticResource names and Base64 content, allowing path traversal and arbitrary file writes because only / was used when extracting the file name. This issue is fixed in version 2.10.23.

Check this codebase for CVE-2026-45419 and fix it if it is affected.

What it is: CVE-2026-45419 is a high-severity path traversal vulnerability in dataease, published on 15 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45419 exists.

Affected product: dataease. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
