## What is CVE-2026-2604?

CVE-2026-2604 is a medium-severity path traversal vulnerability in GNOME Evolution Data Server, published on 16 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

A flaw was found in evolution-data-server. Inconsistent comparison logic in the addressbook file backend allows a Flatpak application with D-Bus access to craft a malicious URI containing directory traversal sequences. This URI is stored without proper validation during contact creation or modification. Later, during contact deletion, the URI is processed with a less strict check, leading to the deletion of arbitrary files on the host filesystem. This could potentially include critical Flatpak override files.

Weakness: CWE-73 (External Control of File Name or Path)

Check this codebase for CVE-2026-2604 and fix it if it is affected.

What it is: CVE-2026-2604 is a medium-severity path traversal vulnerability in GNOME Evolution Data Server, published on 16 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-2604 exists.

Affected product: GNOME Evolution Data Server. 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.
