RE: ProGet - Yanked package behaviour
Thanks @dean-houston
That all makes sense. If a Vulnerability is identified in a package that has been downloaded, will ProGet remove that from storage?
We are trying to identify what containment actions we need to take in case we identify a high vulnerability package that needs to be removed from our network entirely.

ProGet - Yanked package behaviour
Hi,
Could you please explain the behaviour around how ProGet handles yanked packages for public feeds?
Scenarios:
-
The package is yet to be downloaded to ProGet, and the user attempts to download a janked version. I'm sure ProGet will block the download in this case.
-
The package has been downloaded to ProGet, and is then yanked from the remote. Will ProGet update it's feed index to mark it is yanked and also remove any local files that have been previous downloaded?
This is mainly aimed at PyPi - but I guess the same behaviour would apply to other feed types.
Thanks!

RE: ProGet pnpm audit reports no vulnerabilities
Hi,
Thanks for the speedy reply! We investigated your ideas and can confirm that both the npm and pnpm CLIs are calling the newer /bulk endpoint that ProGet implements.
We decided to build a simple mock API that implements the audit endpoint. That we can easily play around with the JSON response to see what is causing the issues.
pnpm
Reproduction steps:
- Setup a simple web server to respond to any POST request with a json payload.
- Test pnpm against the payload from registry.npmjs. Works as expected.
- Stringify the existing ids. No known vulnerabilities found.
Outcome:
It is the the non-numeric IDs that are causing the issue with pnpm. You can see in pnpm source that they have typed the ID field response as a number, I didn't look any further in the source code and just assume that there is some validation/catch to handle non-numeric ids.The lack of a formal schema from GitHub really doesn't make this easy to implement - so no wonder there are issues with other npm clients! It appears the general sentiment is to follow the npm-cli source code for the endpoint schema which it looks like you have done, although it is Javascript and not typed or obvious what each field is meant to contain
.It does however look like the limited unit tests for the audit command are only using numbers for the id field - which may implicitly reference that the field is meant to only contain a number.
To ensure consistency with the public npm registry, would it be possible to change ProGet to use a number for the id field on the audit response? The public npm registry appears to be the only "standard" and so to prevent issues with future npm releases/clients - can I please get your thoughts on this?
Yarn & Bun
We also test Yarn and Bun to see how they behave...
Neither of them appeared to care about the id being a string, however the results were still not consistent.
Bun: Shows 3/3 Vulnerabilities, correct
️
Yarn (v2+): Shows 1/3 Vulnerabilities, incorrect
️. I assume this is because 2 out of 3 have nullfor the severity field value.Thanks!

ProGet pnpm audit reports no vulnerabilities
Hi,
We are having issues with pnpm not picking up the package vulnerabilities when running
pnpm audit. It always returns no vulnerabilities when pointing at ProGet, but returns correct results when querying the public npm registry.It looks like
npm auditdoes work as expected, so this is specific to whatever pnpm is expecting.Looking at the response from npmjs and ProGet, the only real difference I can see is that ProGet is not always setting
severity, and that there are some encoding issues in thevulnerable_versionsandtitlefields.{ "lodash": [ { "id": 1120370, "url": "https://github.com/advisories/GHSA-xxjr-mmjv-4gpg", "title": "Lodash has Prototype Pollution Vulnerability in `_.unset` and `_.omit` functions", "severity": "moderate", "vulnerable_versions": ">=4.0.0 <=4.17.22", "cwe": ["CWE-1321"], "cvss": { "score": 6.5, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L" } }, { "id": 1115806, "url": "https://github.com/advisories/GHSA-r5fr-rjxr-66jc", "title": "lodash vulnerable to Code Injection via `_.template` imports key names", "severity": "high", "vulnerable_versions": ">=4.0.0 <=4.17.23", "cwe": ["CWE-94"], "cvss": { "score": 8.1, "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H" } }, { "id": 1115810, "url": "https://github.com/advisories/GHSA-f23m-r3pf-42rh", "title": "lodash vulnerable to Prototype Pollution via array path bypass in `_.unset` and `_.omit`", "severity": "moderate", "vulnerable_versions": "<=4.17.23", "cwe": ["CWE-1321"], "cvss": { "score": 6.5, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L" } } ] }ProGet:

RE: PEP 700 conformance for PyPI feeds
Hi @stevedennis
I upgraded our dev server to 2026.1 and we are still having issues with the upload-time property. It appears that ProGet will only add the upload-time property when the package has been pulled to ProGet, i.e. not present for remotes.

property, this is because I manually pulled these version to ProGet.
upload-timeshould always be present prior to pulls so that client package managers like uv withexclude-newer = "7 days"can avoid pulling new packages that will be blocked by ProGet due to non-compliance rules. -
RE: PEP 700 conformance for PyPI feeds
Hi @dean-houston,
Can I confirm that this was fixed in the ProGet 2026 26.0.0 release last week?
PG-3272
Major Release ProGet 2026 We are experiencing issues with UV attempting to resolve packages that are too new when configured with the "exclude-newer" property, presumably because it's looking for the
upload-timeand notpublishedin the response.For info, we are currently seeing non-PEP 700 compliance on version 2025.27
Thanks,

ProGet Package Download Statistics IP when behind Load Balancer
Hi,
We are running 2x ProGet servers in High Availability behind a load balancer. We are only seeing the load balancer IP on the package download statistics in ProGet.
We have enabled X-Forwarded-For on the load balancer to forward on the Client-IP but this has had not had any impact. Is there another header value we should be sending? Apologies if this is documented somewhere, I couldn't find it!
Thanks,

RE: NPM Incorrect Handling of min-release-age
Thanks @atripp, that makes sense.
I was having another issue with pgutil which turned out to be my fault, however I believe there is a follow on issue to do with the compliance analysis for project builds that have yet to have been pulled to ProGet. More detail on my original post here: https://forums.inedo.com/topic/5733/proget-unable-to-publish-sbom-from-pgutil/4.
@Dan_Woolf suggested continuing the topic here as it's related to non-compliant packages and what I believe to be the recently published rule. Is this something you can take a look at?
Thanks!
