- cve / CVE-2026-45829 / GHSA-f4j7-r4q5-qw2c / severity:CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P / chromadb / PyPI

## Details
**Severity:** CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P
**Advisory:** GHSA-f4j7-r4q5-qw2c (CVE-2026-45829)

**Affected (your watchlist):**
