## What is CVE-2024-35236?

CVE-2024-35236 is a medium-severity cross-site scripting vulnerability in advplyr audiobookshelf, published on 27 May 2024. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

### Official description

Audiobookshelf is a self-hosted audiobook and podcast server. Prior to version 2.10.0, opening an ebook with malicious scripts inside leads to code execution inside the browsing context. Attacking a user with high privileges (upload, creation of libraries) can lead to remote code execution (RCE) in the worst case. This was tested on version 2.9.0 on Windows, but an arbitrary file write is powerful enough as is and should easily lead to RCE on Linux, too. Version 2.10.0 contains a patch for the vulnerability.

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

What it is: CVE-2024-35236 is a medium-severity cross-site scripting vulnerability in advplyr audiobookshelf, published on 27 May 2024. An attacker needs administrator access to exploit it, 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-2024-35236 exists.

Affected product: advplyr audiobookshelf. 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.
