chore(deps): resolve dependency vulnerabilities (2026-08-17)

[tkislan]

npx better-npm-audit audit was failing, but not because new advisories landed. All four .nsprc accepted-risk entries expired on 2026-08-15, so the same four advisories that had been suppressed became visible again.

Each was re-assessed independently against the current registry. Three of the four rationales had gone stale — fixes were published after those notes were written — so they are fixed for real here rather than re-suppressed. One genuine accepted risk remains.

Decisions

Advisory	Package	Sev	Remediation	Why this rung
GHSA-vpq2-c234-7xj6	@tootallnate/once	low	Override 2.0.1	Transitive; a 2.x backport now exists
GHSA-w5hq-g745-h8pq	uuid	moderate	Override uuid@8 → 11.1.1	Transitive; direct dep already clean
GHSA-8988-4f7v-96qf	@opentelemetry/core	moderate	Direct bump @vscode/extension-telemetry → ^1.5.2	No override possible; the owning dep is direct
GHSA-848j-6mx2-7j84	elliptic	low	Accepted risk, expiry 2026-09-17	No published fix exists anywhere

@tootallnate/once → override 2.0.1

2.0.1 is a backport published 2026-05-03, after the note claiming no fix existed. Two corrections to that note: all three copies are production, not dev-only — the 1.1.2 copy is reached through @deepnote/sql-language-server → sqlite3 → node-gyp → make-fetch-happen, not only via @vscode/test-electron.

A plain pin also moves the 1.1.2 copy across a major. That is safe here because every consumer in the tree is http-proxy-agent calling once(socket, 'connect') at dist/agent.js:139 with the resolved value discarded, so the 1.x→2.x deltas (resolves args[] rather than args[0]; drops .spread/.cancel) are inert. Not taken to 3.0.1: it is ESM-only and all consumers are CJS.

   "immutable": "4.3.9",
-  "js-yaml@3": "3.15.1"
+  "js-yaml@3": "3.15.1",
+  "@tootallnate/once": "2.0.1",

uuid → override uuid@8: 11.1.1

The old note's premise (only fix is >=11.1.1) was right; its conclusion that this is unsafe was not. 11.1.1 still ships a real CJS build (main: ./dist/cjs/index.js) and its export surface is a superset of 8.3.2's. All five consumers call v4() with no buf argument — the explicitly unaffected path.

Pinned to 11.1.1 specifically because 12.0.1 and later are ESM-only. The ranged key mirrors the existing "js-yaml@3" entry, which likewise coexists with a newer direct dependency — uuid stays at ^13.0.2, which was never in range.

+  "uuid@8": "11.1.1"

@opentelemetry/core → bump @vscode/extension-telemetry to ^1.5.2

No 1.x backport exists (the fix is 2.8.0), so no override was possible — forcing core to 2.x breaks applicationinsights@2.5.0, which calls symbols removed in otel 2.x. Bumping the direct dependency past 0.9.0 drops applicationinsights and with it @opentelemetry/core, sdk-trace-base and resources, so this removes the advisory and three chained entries instead of suppressing them.

^1.5.2 specifically, because every release from 0.9.0 through 1.4.0 has an undeclared dependency: they import @microsoft/applicationinsights-common without declaring it, relying on applicationinsights-web-basic to supply it transitively. web-basic 3.4.x dropped it, so those versions fail to bundle:

node_modules/@vscode/extension-telemetry/dist/node/common/appInsightsClientFactory.js:31:45:
ERROR: Could not resolve "@microsoft/applicationinsights-common"

1.5.2 is the first release whose declared dependencies match what it imports. engines.vscode is unchanged at ^1.75.0.

-  "@vscode/extension-telemetry": "^0.7.7",
+  "@vscode/extension-telemetry": "^1.5.2",

1.0.0 replaced export default class TelemetryReporter with a named export, which costs four mechanical edits:

 // src/platform/telemetry/index.ts, src/test/testHooks.node.ts
-import TelemetryReporter from '@vscode/extension-telemetry';
+import { TelemetryReporter } from '@vscode/extension-telemetry';

 // src/test/unittests.ts — CJS Module._load hook
-return { default: vscMockTelemetryReporter };
+return { TelemetryReporter: vscMockTelemetryReporter };

 // build/mocha-esm-loader.js — synthesized ESM mock module
-export default vscMockTelemetryReporter;
+export const TelemetryReporter = vscMockTelemetryReporter;

That last one is the non-obvious one: the test loader synthesizes the telemetry mock as source and exported it only as a default, so import { TelemetryReporter } failed ESM instantiation with "does not provide an export named 'TelemetryReporter'" — even though the real package lexes fine. It now matches 1.5.2's actual shape.

elliptic → accepted risk renewed

The only entry with no remediation available: the advisory range is <=6.6.1 and 6.6.1 is the latest published version, so no override or lockfile bump can move it. It is dev-only and absent from the production tree.

Notes corrected to add the create-ecdh path the previous revision omitted, and to record why it is unreachable: node-stdlib-browser is a devDependency whose polyfill plugin is gated to the web test entry (build/esbuild/build.ts), whose output .vscodeignore excludes from the VSIX.

⚠️ Correction worth reviewing

The .nsprc note for @opentelemetry/core asserted that telemetry is disabled so the propagator is never exercised. That was false. isTelemetryDisabled() (src/platform/telemetry/index.ts:39-41) does not gate the send path — sendTelemetryEvent gates on isTelemetrySupported(), which always constructs the reporter, so App Insights events are sent in production.

The advisory was still not exploitable here (the vulnerable code is the inbound W3CBaggagePropagator.extract() parse, and this extension has no inbound listener), but the risk had been accepted on the wrong grounds. Since PostHog is now the live analytics path, deleting the App Insights path outright would remove this dependency class permanently — flagged, not done here.

Verification

All run locally on this branch:

• npm run compile-release → exit 0 (the exact command the 3 build jobs run)
• npm run compile → exit 0
• npx better-npm-audit audit → exit 0
• npx better-npm-audit audit --production → exit 0
• npm run compile-tsc → exit 0
• npm run test:unittests → 2545 passing, 0 failing (unchanged from baseline)
• Tree confirms @opentelemetry/core, applicationinsights and uuid@8.3.2 are gone; @tootallnate/once resolves to a single 2.0.1

Not verified: 1.5.x sends through the 1DS channel rather than the Node App Insights SDK. Worst realistic failure is App Insights events silently stopping — low impact given PostHog is the live analytics path, but it is not observable without checking the AI dashboard.

Fully reversible — revert the files and npm install. No migration.

📝 Walkthrough

Walkthrough

The package manifest updates @vscode/extension-telemetry and pins transitive dependencies. The SQL language server build configuration propagates the @tootallnate/once override. Telemetry imports and test mocks now use the named TelemetryReporter export. The .nsprc entry expands the elliptic vulnerability notes and extends the risk expiry date.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to 2224a

The dependency updates remove the affected vulnerable packages while the supplied compile, audit, and unit-test checks pass; only minor documentation clarification remains, so no actionable merge-blocking risk remains after normal review.

GitHub advisory GHSA-848j-6mx2-7j84 patched upstream version elliptic CVE-2025-14505 npm override transitive dependency documentation

💡 Result:

CVE-2025-14505 (tracked as GHSA-848j-6mx2-7j84) is a cryptographic vulnerability in the npm package elliptic (all versions <= 6.6.1) [1][2][3]. It stems from an incorrect calculation of the byte-length of 'k' during ECDSA signature generation, which leads to truncation when 'k' has leading zeros [1][4]. This can produce invalid signatures and, under specific conditions, allow an attacker to derive the secret signing key [1][5]. As of August 18, 2026, there is no official patched version published by the upstream elliptic maintainers [6][7]. While a pull request containing a fix has been identified in the repository [4], it has not been merged or released as a stable version [8]. Consequently, remediation for transitive dependencies must rely on manual intervention [9][10]. To address this vulnerability, you can use the npm overrides field in your package.json to force the use of a patched version or to apply the upstream fix [9][10]. Because no official release exists, many users have adopted the following strategies: 1. Override with an alternative: Some projects have opted to migrate away from elliptic to other libraries, such as @noble/curves, to mitigate the risk entirely [11]. 2. Manual Patching: You can use tools like patch-package to apply the known upstream fix directly to your node_modules directory, ensuring the fix is reapplied during subsequent installs [4][9]. 3. Dependency Override: If a fork or a specific patched version becomes available (e.g., through third-party support services like HeroDevs) [8], you can force your project to use it by adding the following to your package.json: { "overrides": { "elliptic": "patched-version-or-fork" } } Always verify the fix by running your test suite, as forcing an override can occasionally introduce breaking changes if the parent dependency depends on specific behaviors of the vulnerable version [9][10].

Use precise override wording.

Replace “No override is possible” with “No patched upstream release is currently available.” npm overrides can point to a patched fork or alternative package.
