No CVSS score has been assigned to GHSA-2944-57xv-2682 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-2944-57xv-2682?

GHSA-2944-57xv-2682 affects the following packages: @asymmetric-effort/specifyjs (npm). Ecosystems affected: npm.

How do I fix GHSA-2944-57xv-2682?

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.

How do I detect GHSA-2944-57xv-2682 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @asymmetric-effort/specifyjs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-2944-57xv-2682 if there is no patch (or I can't update yet)?

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.

Is GHSA-2944-57xv-2682 actively exploited in the wild?

No public exploit code has been indexed for GHSA-2944-57xv-2682 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

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.
