From the system log:
Aug 07 19:13:33 pdns-recursor[169249]: msg="Not validating response for security status update, this is a non-release version" subsystem="housekeeping" level="0" prio="Warning" tid="0" ts="1786122813.866" query="recursor-4.8.8-1_deb12u1.Debian.security-status.secpoll.powerdns.com" version="4.8.8-1+deb12u1.Debian"
Since the package can't be updated without updating the entire VyOS installation, even if the check worked, performing it in the first place seems a bit silly and I think it should be disabled by setting security-poll-suffix in the config file: https://doc.powerdns.com/authoritative/settings.html#setting-security-poll-suffix
Perhaps the check could also be fixed by adjusting the build process to bake a version into the executable that is understood by secpoll.powerdns.com, though that doesn't really seem right to me either, not sure if VyOS carries a custom patchset.
Either way, in its current state it's just noise in the logs.
I've not seen this reported anywhere, only found the same log message in this VyOS forum post from 2024, so it's not a new issue.
