CVE-2026-110866 — Renovate before 44.61.3 minimumReleaseAge Bypass via PR Rebase Request
Renovate before 44.61.3 contains a protection mechanism bypass vulnerability that allows minimumReleaseAge checks to be skipped when a user requests a PR rebase via the rebase/retry checkbox. Attackers who publish a malicious dependency version can have it pushed into the PR and run in CI before the required release age elapses.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Mend Mend-renovate-ce Helm Chart, Mend Mend-renovate-enterprise-edition Helm Chart, Mend Renovate-ce…).
- The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Exploitation requires user interaction: tighten email/web filtering and warn affected users.
- Search available logs for exploit probes, errors and authentication anomalies.
