The changed code was only introduced 1 week ago (is not in any release).

Oh, okay, the CVE text was wrong. Sometimes I've learned to doubt it, clearly not right here.
Comment 4 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2021-01-06 00:47:58 UTC
The text was later updated, FWIW:
"** DISPUTED ** DCTStream::getChars in DCTStream.cc in Poppler 20.12.1 has a heap-based buffer overflow via a crafted PDF document. NOTE: later reports indicate that this only affects builds from Poppler git clones in late December 2020, not the 20.12.1 release. In this situation, it should NOT be considered a Poppler vulnerability. However, several third-party Open Source projects directly rely on Poppler git clones made at arbitrary times, and therefore the CVE remains useful to users of those projects."
