## What is CVE-2025-34452?

CVE-2025-34452 is a high-severity path traversal vulnerability in Streama, published on 18 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Streama versions 1.10.0 through 1.10.5 and prior to commit b7c8767 contain a combination of path traversal and server-side request forgery (SSRF) vulnerabilities in that allow an authenticated attacker to write arbitrary files to the server filesystem. The issue exists in the subtitle download functionality, where user-controlled parameters are used to fetch remote content and construct file paths without proper validation. By supplying a crafted subtitle download URL and a path traversal sequence in the file name, an attacker can write files to arbitrary locations on the server, potentially leading to remote code execution.

Weakness: CWE-918 (Server-Side Request Forgery), CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-34452 and fix it if it is affected.

What it is: CVE-2025-34452 is a high-severity path traversal vulnerability in Streama, published on 18 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-34452 in the wild and no public exploit code.

Affected product: Streama. 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.
