Renovate previously needed a separate packageRule for each groupId, and security updates were never grouped: Renovate forces their groupName to null, so log4j-core and log4j-1.2-api opened as separate PRs (apache#6691 and apache#6690) even though both bump to the same 2.25.4. Add a catch-all rule that groups every Maven update by its groupId, and a vulnerabilityAlerts block that applies the same grouping to security updates. Drop the per-groupId rules the catch-all now covers, keeping only the rules that do more than restate a single groupId: groups that span several groupIds (errorprone, classic commons, xalan/xerces, vlsi, helger, gradle, kotlin), version pins (slf4j, xml-apis), disabled entries (guava, internal src:protocol), and the GitHub Actions group. Verified with renovate-config-validator and a `renovate --platform=local` dry run: log4j keeps all four artifacts in one branch, and bouncycastle, activemq, tika, commons, and lets-plot each stay grouped by groupId through the catch-all.

2.25.3→2.25.4Apache Log4j 1 to Log4j 2 bridge: silent log event loss in Log4j1XmlLayout due to unescaped XML 1.0 forbidden characters
CVE-2026-34479 / GHSA-h383-gmxw-35v2
More information
Details
The
Log4j1XmlLayoutfrom the Apache Log4j 1-to-Log4j 2 bridge fails to escape characters forbidden by the XML 1.0 standard, producing malformed XML output. Conforming XML parsers are required to reject documents containing such characters with a fatal error, which may cause downstream log processing systems to drop or fail to index affected records.Two groups of users are affected:
Log4j1XmlLayoutdirectly in a Log4j Core 2 configuration file.org.apache.log4j.xml.XMLLayoutspecified as the layout class.Users are advised to upgrade to Apache Log4j 1-to-Log4j 2 bridge version
2.25.4, which corrects this issue.Severity
