@asymmetric-effort/specifyjs: `data:` URI allowed without size restriction
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
@asymmetric-effort/specifyjsnpmDescription
Finding
Location: core/src/shared/secure-fetch.ts:33-35
data: URIs were allowed without any restriction. While data: URIs don't make network requests, they can be used for memory exhaustion via very large data URIs.
Status
Fixed in v0.2.136 — data: URIs are now limited to 1MB. URIs exceeding this limit throw an error.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @asymmetric-effort/specifyjs. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update @asymmetric-effort/specifyjs to 0.2.136 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2944-57xv-2682 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-2944-57xv-2682 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-2944-57xv-2682. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-2944-57xv-2682 in your dependencies?
O3 detects GHSA-2944-57xv-2682 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
