Exploitation and risk

Source status

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Ansible-core: ansible-core: ansible.builtin.git invokes git without a `--` separator, allowing argument injection via a `-`-leading repository url (e.g. --upload-pack) -> rce

A flaw was found in ansible-core's ansible.builtin.git module. The module invokes git (ls-remote, clone, fetch) with the repository URL as a positional argument and without a "--" separator, so a repository URL that begins with a dash is interpreted by git as a command-line option. A caller that passes an attacker-controlled repository URL to the module can trigger argument injection (for example --upload-pack/--exec), resulting in arbitrary command execution on the host running the module.
