## What is CVE-2024-45194?

CVE-2024-45194 is a medium-severity cross-site scripting vulnerability in Synacor Zimbra Collaboration Suite, published on 21 Nov 2024. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

### Official description

In Zimbra Collaboration (ZCS) 9.0 and 10.0, a vulnerability in the Webmail Modern UI allows execution of stored Cross-Site Scripting (XSS) payloads. An attacker with administrative access to the Zimbra Administration Panel can inject malicious JavaScript code while configuring an email account. This injected code is stored on the server and executed in the context of the victim's browser when interacting with specific elements in the web interface. (The vulnerability can be mitigated by properly sanitizing input parameters to prevent the injection of malicious code.)

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Check this codebase for CVE-2024-45194 and fix it if it is affected.

What it is: CVE-2024-45194 is a medium-severity cross-site scripting vulnerability in Synacor Zimbra Collaboration Suite, published on 21 Nov 2024. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2024-45194 in the wild and no public exploit code.

Affected product: Synacor Zimbra Collaboration Suite. 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.
