## What is CVE-2026-19910?

CVE-2026-19910 is a high-severity vulnerability in PAX Technology Q80, published on 14 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

PAX Technology Q80 Application Installer Signature Verification Bypass Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of PAX Technology Q80. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the application installer. The issue results from the lack of proper verification of a cryptographic signature before installing an application. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-30585.

Weakness: CWE-347 (Improper Verification of Cryptographic Signature)

Check this codebase for CVE-2026-19910 and fix it if it is affected.

What it is: CVE-2026-19910 is a high-severity vulnerability in PAX Technology Q80, published on 14 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-19910 in the wild and no public exploit code.

Affected product: PAX Technology Q80. 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.
