## What is CVE-2025-0126?

CVE-2025-0126 is a high-severity authentication bypass vulnerability in Palo Alto Networks Cloud NGFW, published on 11 Apr 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

When configured using SAML, a session fixation vulnerability in the GlobalProtect™ login enables an attacker to impersonate a legitimate authorized user and perform actions as that GlobalProtect user. This requires the legitimate user to first click on a malicious link provided by the attacker.

The SAML login for the PAN-OS® management interface is not affected. Additionally, this issue does not affect Cloud NGFW and all Prisma® Access instances are proactively patched.

Affected product: Palo Alto Networks Cloud NGFW. 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.
