@zooba You have to go the the CVE Dictionary and search it or download the entire dataset. They helpfully disallow queries under 3 characters so "xz" won't do, and this caused me to not find the right CPE. Searching for "xz tukaani" lets you find the right one and confirm the linkage to CVE-2024-3094 (xz-utils backdoor). |

I just searched the whole string as shown in the file and it found the right one (not the one with the most recent CVE, of course). So that's good to know. |

Previous CPE identifier was for an xz Go package, not for the upstream package (isn't CPE fun?) Confirmed that this CPE works to detect the recent backdoor CVE by manually faking the metadata for 5.6.1 and running Grype. Will need a backport to 3.12 as well.
