## What is CVE-2026-103316?

CVE-2026-103316 is a high-severity vulnerability in Logius DigiD for macOS, published on 13 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The macOS version of the DigiD app is not signed with Hardened Runtime. As a result, a local process can load its own dylib into DigiD via DYLD_INSERT_LIBRARIES.  An attacker with local user-level code execution can execute arbitrary code within the macOS version of the DigiD app, thereby gaining access to DigiD data and cryptographic capabilities that the process normally does not have.

Exploitation: There is no known exploitation of CVE-2026-103316 in the wild and no public exploit code.

Affected product: Logius DigiD for macOS. 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.
