## What is CVE-2025-54593?

CVE-2025-54593 is a high-severity code injection vulnerability in FreshRSS, published on 1 Aug 2025. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

FreshRSS is a free, self-hostable RSS aggregator. In versions 1.26.1 and below, an authenticated administrator user can execute arbitrary code on the FreshRSS server by modifying the update URL to one they control, and gain code execution after running an update. After successfully executing code, user data including hashed passwords can be exfiltrated, the instance can be defaced when file permissions allow. Malicious code can be inserted into the instance to steal plaintext passwords, among others. This is fixed in version 1.26.2.

Weakness: CWE-94 (Improper Control of Generation of Code)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-54593 and fix it if it is affected.

What it is: CVE-2025-54593 is a high-severity code injection vulnerability in FreshRSS, published on 1 Aug 2025. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-54593 exists.

Affected product: FreshRSS. 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.
