## What is CVE-2024-45045?

CVE-2024-45045 is a medium-severity cross-site scripting vulnerability in CollaboraOnline online, published on 29 Aug 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Collabora Online is a collaborative online office suite based on LibreOffice technology. In the mobile (Android/iOS) device variants of Collabora Online it was possible to inject JavaScript via url encoded values in links contained in documents. Since the Android JavaScript interface allows access to internal functions, the likelihood that the app could be compromised via this vulnerability is considered high. Non-mobile variants are not affected. Mobile variants should update to the latest version provided by the platform appstore. There are no known workarounds for this vulnerability.

What it is: CVE-2024-45045 is a medium-severity cross-site scripting vulnerability in CollaboraOnline online, published on 29 Aug 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2024-45045 in the wild and no public exploit code.

Affected product: CollaboraOnline online. 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.
