Is the latest zero-day exploit (CVE-2021-41773) fixed in fully patched Ubuntu 20.04.3 LTS?

I never understood how Ubuntu manages Apache versions, so the question: is Ubuntu 20.04.03 LTS vulnerable to the CVE-2021-41773 (a path traversal attack to map URLs to files outside the expected document root)? More info on the vulnerability:

Does this answer your question? [How can I tell if a CVE has been fixed in Ubuntu's repositories?](https://askubuntu.com/questions/563408/how-can-i-tell-if-a-cve-has-been-fixed-in-ubuntus-repositories)

@Bruni, no it does not. If I search https://ubuntu.com/security/cve?q=CVE-2021-41773 it returns 0 results. Also, as I understand, the vulnerability exists only in Apache 2.4.49, but not in 2.4.50 or 2.4.48, but Ubuntu 20.04.3 LTS shows Apache/2.4.41 no matter how many updates it has installed. So it may be vulnerable if they have merged changes from the v2.4.49. Or am I wrong?

only security patches from later versions are patched (if any).

@MarisB. It's second in the list in https://ubuntu.com/security/cve?q=&package=apache2 and all releases are marked as "Not vulnerable"

This is also true for 20.04.03

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
