docs(security): record Mend triage for four unremediable findings#14617erichare wants to merge 1 commit into
Conversation
Mend continues to flag transformers 5.8.1, chromadb 1.5.9, diskcache 5.6.3, and accelerate 1.14.0 on release-1.11.4. None of the four can be fixed by a version bump, so this change records the evidence rather than churning deps. No dependency constraints change; `uv lock --check` is clean. transformers 5.8.1 and accelerate 1.14.0 are false positives. The highest first_patched_version across every published transformers advisory is 5.5.0, and an NVD CPE query for transformers 5.8.1 returns zero results. accelerate has zero advisories in GHSA, OSV, and NVD, and 1.14.0 is its latest release. chromadb 1.5.9 and diskcache 5.6.3 have no released fix. chromadb 1.5.9 is the newest release on PyPI (2026-05-05), predating the advisory (2026-05-18); the fix for CVE-2026-45829 is merged upstream as chroma-core/chroma#7237 but unreleased. diskcache 5.6.3 is that project's final release (2023) and it is unmaintained. Neither is reachable as scanned. CVE-2026-45829 is a pre-auth injection in Chroma's Python FastAPI server; Langflow never runs that server, using chromadb only as a client (PersistentClient, CloudClient, HttpClient). It is also not droppable -- chromadb backs the Knowledge Base. diskcache requires local write access to the cache directory and arrives two levels inside the opt-in opendsstar extra (-> ragworkbench -> unitxt), which is absent from `all`, from `complete`, and from the root langflow package. Adds .github/mend-scan-notes.md with the per-finding rationale, the advisory query recipe to verify a patched version exists before raising any floor, and a note that the scan exports --all-extras --all-groups (the maximal closure, not what ships). Cross-references it from each affected declaration.

Tracking issue for the chromadb bump: #14618 — to be actioned as soon as a release newer than 1.5.9 ships. |

Fail closed when advisory APIs fail.
The curl -s pipelines can convert HTTP errors or JSON error objects into empty or null results while returning success. Use set -euo pipefail, --fail-with-body --show-error, and explicit response-schema validation before accepting a waiver.

🌐 Web query:
GitHub REST global security advisories GET /advisories pagination per_page page cursor before after documentation
💡 Result:
The GitHub REST API endpoint for global security advisories (GET /advisories) supports cursor-based pagination using the before and after parameters, as well as page size control via per_page [1][2][3]. Parameters for pagination: - per_page (integer): Controls the number of results returned per page, with a maximum of 100 [1][3]. The default value is 30 [1][4]. - after (string): A cursor that allows you to fetch results after a specified point [1][3]. - before (string): A cursor that allows you to fetch results before a specified point [1][3]. As with other GitHub REST API endpoints, you should use the Link header provided in the API response to handle pagination [5][6]. This header contains URLs for navigating through pages using the appropriate cursor or page parameters [5]. It is recommended to follow the URLs provided in the Link header rather than manually constructing pagination queries [5].

Paginate the advisory query and compare PEP 440 versions.
per_page=100 returns only one page. Use gh api --paginate --slurp, flatten all pages, and replace lexical jq sort with PEP 440-aware comparison before selecting the highest first_patched_version. Otherwise, the query can omit advisories or rank 5.10.0 below 5.9.0.

🌐 Web query:
NVD CVE API 2.0 cpeName exact CPE name filter documentation empty results
💡 Result:
The NVD CVE API 2.0 uses the cpeName parameter to retrieve CVEs associated with specific CPE match criteria [1]. If your query returns empty results, it is often due to the following behaviors or common pitfalls: Filtering Logic: The cpeName parameter is compared against the CPE Match Criteria within a CVE's applicability statement [1]. It is not performing a simple string match against a database of CPE names, but rather evaluating whether the provided CPE name "matches" (is covered by) the match criteria defined by the NVD for specific CVEs [1][2]. If no CVEs have applicability statements that include the provided cpeName, the API will return no results [3]. Narrow Parameters: As documented by the NVD, a 200 OK status with an empty response body is standard behavior when the request is valid but the filter parameters are so narrow that no records match [3]. CPE Format: The cpeName requires a CPE 2.3 formatted string [4]. While partial matches are sometimes supported [1][5], the syntax must be correct (13 colon-separated values) [1]. Ensure that the part, vendor, product, and version components contain values other than "*" to properly target specific products [1]. API Interaction Pitfalls: - Multiple Parameters: If you include both cpeName and virtualMatchString in the same request, the API will only use the cpeName parameter [2]. - isVulnerable: If you use the isVulnerable=true filter, it restricts results to only those where the CPE is identified as vulnerable; this must be used in conjunction with cpeName [4][5]. - Case Sensitivity: While documentation states parameter names are case-insensitive, values are generally case-sensitive depending on the underlying data [3]. If you are consistently receiving empty results for a CPE name you believe should have matches, verify the existence of the CPE using the NVD's CPE API or search page, as it is possible the specific version/component you are querying is not explicitly linked to any CVEs in the NVD database [6][7]. [1][3][2]

Use the inclusive macOS conflict boundary in both locations. Because docling-ibm-models>=3.13.3 requires transformers<5.9.0 on Darwin, a floor of >=5.9.0 is already unsatisfiable. Replace “past 5.9.0” with “to 5.9.0 or higher” in .github/mend-scan-notes.md#L63-L68 and src/backend/base/pyproject.toml#L114-L118.

Mend continues to flag four packages on
release-1.11.4. I checked each against the GitHub advisory DB, OSV (PyPA + CVE + GHSA), and NVD directly, and traced the dependency paths in the lock.None of the four can be remediated by a version bump. Two are false positives; two have no released fix upstream. So this PR records the evidence instead of churning dependencies — no constraint changes, and
uv lock --checkis clean.Findings
transformers5.8.1first_patched_versionacross all advisories = 5.5.0. NVD CPE query for 5.8.1 → 0 results.accelerate1.14.0chromadb1.5.9last_affected: 1.5.9,first_patched_version: null.diskcache5.6.3last_affected: 5.6.3,first_patched_version: null.The two false positives
transformers5.8.1 sits above every published patched version. The floor is already>=5.6.0,<6.0.0and must not go past 5.9.0 —docling-ibm-models>=3.13.3declarestransformers<5.9.0; sys_platform == "darwin", so a higher floor makes it unsatisfiable on macOS and uv silently forks the resolution, backtracking the whole docling stack on darwin only. We hit exactly this in a prior round.acceleratehas no advisories anywhere, and 1.14.0 is its latest release. It reaches us opt-in via thedoclingextra.The two with no fix
chromadb. 1.5.9 is the newest release on PyPI (uploaded 2026-05-05), and the advisory published 2026-05-18 — the fix is merged upstream as chroma-core/chroma#7237 but has not shipped. There is nothing to bump to.
It is also not reachable as scanned: CVE-2026-45829 is a pre-authentication injection in Chroma's Python FastAPI server, at
/api/v2/tenants/{tenant}/databases/{db}/collections. Langflow never runs that server — it uses chromadb purely as a client (PersistentClient,CloudClient,HttpClient), so the vulnerable endpoint is never bound. And it can't simply be dropped:langchain-chromais a default dep oflangflow-baseand chromadb backs the Knowledge Base.diskcache. 5.6.3 is that project's final release (2023-08-31) and it is unmaintained, so no fix is coming. The issue is unsafe pickle deserialization requiring an attacker to already hold write access to the cache directory. It arrives two levels inside the opt-in
opendsstarextra (→ragworkbench→unitxt), which is absent fromall, fromcomplete, and from the rootlangflowpackage.Why these keep reappearing
.github/workflows/mend.ymlexports the scan surface withuv export --all-packages --all-extras --all-groups— the maximal closure, including every opt-in extra and dev/test group, not what any user installs. A package appearing in the scan doesn't imply it ships. That's howdiskcache, buried inside an extra nobody installs by default, surfaces as "Critical / Transitive".Changes
.github/mend-scan-notes.md: per-finding rationale, the advisory-query recipe to confirm a patched version actually exists before raising any floor, and a note on the scan surface.langflow-base,lfx, andlfx-bundles.Comments only — no dependency constraints change.
