调研方向
Issue 中没有指定具体的文件或测试。首先跟踪 VulnerableCode 针对外部 advisory 源（MITRE/NVD/GitHub/OSV/GitLab）的 ingestion pipeline，以及合并 title、PURLs 和 CPEs 的字段规范化步骤。通过检查 CVE-2026-50628 在每个阶段的表示方式来复现问题，尤其关注更宽泛的 CPE 数据替换精确的 Maven artifact 数据的位置。完成的标准是：规范化后的 advisory 保留正确的 package 范围，并且不会退化为通用/不正确的产品 metadata。

描述
Some ASF projects are seeing their CVE records appearing mangled in GitHub Advisories, but this is only a symptom of a deeper problem and not specific to the ASF. Thanks for @ppkarwasz for the details
An example is CVE-2026-50628 (disclosed on June 12th), which has a CVSS score of 9.8, and is only present in that PURL pkg:maven/org.apache.cxf/cxf-rt-rs-security-oauth2 and not in the whole CXF codebase.
Here are some background:
-
at MITRE: https://github.com/CVEProject/cvelistV5/blob/main/cves/2026/50xxx/CVE-2026-50628.json or https://www.cve.org/CVERecord?id=CVE-2026-50628 have Maven coordinates properly provided at least in the name
-
at NVD: https://nvd.nist.gov/vuln/detail/CVE-2026-50628 or https://github.com/olbat/nvdcve/blob/master/nvdcve/CVE-2026-50628.json if the NVD is down. See rough history at https://github.com/fkie-cad/nvd-json-data-feeds/commits/main/CVE-2026/CVE-2026-506xx/CVE-2026-50628.json
- initial record mostly empty when pulled from MITRE https://github.com/fkie-cad/nvd-json-data-feeds/blob/bde8d216748790cf40fc461aa9e9351dd7c06e96/CVE-2026/CVE-2026-506xx/CVE-2026-50628.json
- on June 15th, update to add an incorrect CPE, too wide cpe:2.3🅰️apache:cxf, a product with dozens of different artifacts, and not the actual package that is affected https://github.com/fkie-cad/nvd-json-data-feeds/blob/c8e589f587fe50f16712ebc10079e4fde00a1210/CVE-2026/CVE-2026-506xx/CVE-2026-50628.json#L49
- on June 17th, update to get more data from the CVE record with better data https://github.com/fkie-cad/nvd-json-data-feeds/blob/644f9fc5bd0a10688470dc004d55d76098d99f56/CVE-2026/CVE-2026-506xx/CVE-2026-50628.json but the CPE is still wrong.
- On top of that, RedHat later adds CPE-keyed, VEX-like statements of whether their larger products are affected or not https://github.com/fkie-cad/nvd-json-data-feeds/blob/2dd45b48e0efa0fde64742f95da829dc45ea506c/CVE-2026/CVE-2026-506xx/CVE-2026-50628.json
-
at Github: https://github.com/advisories/ghsa-g5v7-jchf-7jrr is initially published with mostly nothing known, no title, no artifact, no affected ranges, and 2 months later still is the same https://github.com/github/advisory-database/blob/dbc1435941d42e394de655b8e344b1aab124a9a4/advisories/unreviewed/2026/06/GHSA-g5v7-jchf-7jrr/GHSA-g5v7-jchf-7jrr.json
Then OSV and GitLab
- Since this is "unreviewed" at Github, Gitlab ignores that advisory https://gitlab.com/search?search=CVE-2026-50628&nav_source=navbar&project_id=12006272&group_id=2452873&search_code=true&repository_ref=master
- The OSV pulls from GitHub and separately from Mitre that was backfilled with the same infor as NVD keeping the incorrect historical CPE published by the NVD https://osv.dev/vulnerability/CVE-2026-50628 and diluting the data further
