Command injection in Renovate hermit manager via malicious dependency names
Is CVE-2026-76231 being exploited?
Not confirmed. CVE-2026-76231 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

How severe is CVE-2026-76231?
CVE-2026-76231 is rated High with a CVSS score of 8.4. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Patch when possible
- affected>= 32.135.0 and < 40.33.0
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
