## What is CVE-2026-85609?

CVE-2026-85609 is a medium-severity server-side request forgery vulnerability in Openpanel-dev openpanel, published on 4 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Openpanel before 2.3.0 contains an unauthenticated full-read server-side request forgery (SSRF) vulnerability in the GET /tools/site-checker endpoint (apps/api/src/controllers/tools.controller.ts). The endpoint passes a user-supplied url query parameter to fetchWithRedirects() and performs server-side HTTP requests to arbitrary URLs without any SSRF/IP validation. An unauthenticated remote attacker can access cloud instance metadata endpoints, probe internal services, scan internal network ports, and read returned content (status code, page size, timing, and parsed HTML metadata), and leak internal IP addresses (via getIPInfo() to a third party).

Weakness: CWE-918 (Server-Side Request Forgery)

What it is: CVE-2026-85609 is a medium-severity server-side request forgery vulnerability in Openpanel-dev openpanel, published on 4 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-85609 exists.

Affected product: Openpanel-dev openpanel. 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.
