`uncbv`: archive extraction is vulnerable to path traversal (zip-slip)
Exploitation and risk
Source statusCISA 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.

Published### Summary `uncbv extract` writes each archive entry to `output_dir.join(entry_filename)` using the filename stored in the archive with no check for `..` components or absolute paths. A malicious `.cbv` / `.cbz` archive whose entry name contains `../` (or an absolute path) can therefore cause files to be written outside the output directory chosen by the user. This is a "zip-slip" / directory-traversal arbitrary file write (CWE-22).
