GraphHopper vs NSD: at a glance
What is GraphHopper?
GraphHopper 11.1 is a security release, and 12.0 prerelease tags have started.
GraphHopper published 11.1 in October as a security release fixing what it calls critical vulnerabilities, without describing them; the attached change list largely repeats 11.0's OSM tag work, plus items such as trip-based public transit routing, scriptable turn penalties and POST /navigate. Alongside it, 12.0-pre1 and 12.0-pre3 tags and an odd 11.0-alpha1 tag appeared with only commit messages. The roughly yearly major cadence (10.0 in late 2024, 11.0 in October 2025) points at 12.0 as the next major.
What is NSD?
NSD's 4.15 line is being shaped by outside researchers' bug reports.
NLnet Labs shipped two NSD releases in October. 4.15.3 fixed four CVEs in the simdzone zone-file parser that only crafted zone files can trigger, a risk mainly for multi-tenant setups where third parties feed zone data. 4.15.4 adds a report-channel EDNS option, a catalog-group-pattern setting that limits which patterns catalog member zones may use, and the UNECE and ISO record types, alongside a long list of fixes credited to researchers at Palo Alto Networks and Tsinghua University.

GraphHopper
2.5DEVOPS
GraphHopper 11.1 is a security release, and 12.0 prerelease tags have started.
◆ Current state
GraphHopper published 11.1 in October as a security release fixing what it calls critical vulnerabilities, without describing them; the attached change list largely repeats 11.0's OSM tag work, plus items such as trip-based public transit routing, scriptable turn penalties and POST /navigate. Alongside it, 12.0-pre1 and 12.0-pre3 tags and an odd 11.0-alpha1 tag appeared with only commit messages. The roughly yearly major cadence (10.0 in late 2024, 11.0 in October 2025) points at 12.0 as the next major.
◆ Where it's heading
The engine's recent work is routing quality, reading OSM tags more faithfully per mode, and that continues in the 11.x list. The 12.0 prereleases suggest the next major is in preparation, but their notes give no content. Security disclosure is thin: 11.1 is labelled critical without naming the issue.
◆ Prediction
A 12.0 release is the next likely major entry given the prerelease tags; its contents can't be read from these entries.
NSD
5.0DEVOPS
NSD's 4.15 line is being shaped by outside researchers' bug reports.
◆ Current state
NLnet Labs shipped two NSD releases in October. 4.15.3 fixed four CVEs in the simdzone zone-file parser that only crafted zone files can trigger, a risk mainly for multi-tenant setups where third parties feed zone data. 4.15.4 adds a report-channel EDNS option, a catalog-group-pattern setting that limits which patterns catalog member zones may use, and the UNECE and ISO record types, alongside a long list of fixes credited to researchers at Palo Alto Networks and Tsinghua University.
◆ Where it's heading
Most of the 4.15 cycle is reactive: four security or bug-fix releases since August, with outside researchers finding parser overflows, crashes on malformed catalog zones and IXFR edge cases. Features still arrive, and at least one, catalog-group-pattern, was suggested by a researcher who also reported bugs. Catalog zones and zone-file parsing are where the attention is concentrated.
◆ Prediction
Expect more fixes in catalog zone and zone-file parsing as outside fuzzing continues, likely in another 4.15 patch. The entries give no sign of a 4.16 feature release.
