Never scan systems you do not own or have explicit written permission to test.* * Documentation: * Source: ### Package name * vulnapi --- ### License * MIT --- ### Last updated * 30 August 2026 - latest/stable * 30 August 2026 - latest/edge --- ### Websites * [www.cerberauth.com](https://www.cerberauth.com/vulnapi/ "https://www.cerberauth.com/vulnapi/") * [www.cerberauth.com](https://www.cerberauth.com/docs/vulnapi/ "https://www.cerberauth.com/docs/vulnapi/") --- ### Contact * [www.cerberauth.com](https://www.cerberauth.com/ "https://www.cerberauth.com/") --- ### Source code * [github.com/cerberauth/vulnapi](https://github.com/cerberauth/vulnapi "https://github.com/cerberauth/vulnapi") --- ### Report a bug * [github.com/cerberauth/vulnapi/issues](https://github.com/cerberauth/vulnapi/issues "https://github.com/cerberauth/vulnapi/issues") --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/vulnapi/rhel#report-snap-modal) --- ## Enable snaps on Red Hat Enterprise Linux and install VulnAPI Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd Snap is available for [Red Hat Enterprise Linux (RHEL) 8](https://www.redhat.com/en/enterprise-linux-8) and RHEL 7, from the 7.6 release onward. The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below. The EPEL repository can be added to **RHEL 9** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 8** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 7** with the following command: ``` sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ``` Adding the *optional* and *extras* repositories is also recommended: ``` sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` Either log out and back in again or restart your system to ensure snap’s paths are updated correctly. ### Install VulnAPI To install VulnAPI, simply use the following command: ``` sudo snap install vulnapi ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
