GHSA-2944-57xv-2682: @asymmetric-effort/specifyjs: `data:` URI allowed without size restriction
The @asymmetric-effort/specifyjs package allowed use of data: URIs without any size restriction, which could lead to memory exhaustion via very large data URIs. This vulnerability was fixed in version 0.2.136 by limiting data: URIs to 1MB, with larger URIs causing an error.
AI Analysis
Technical Summary
The vulnerability in @asymmetric-effort/specifyjs involved unrestricted acceptance of data: URIs in the code at core/src/shared/secure-fetch.ts lines 33-35. Although data: URIs do not trigger network requests, their unrestricted size could be exploited to cause memory exhaustion. The issue was addressed in version 0.2.136 by enforcing a 1MB size limit on data: URIs, rejecting any that exceed this threshold.
Potential Impact
Unrestricted data: URIs could be used to cause memory exhaustion in applications using affected versions of @asymmetric-effort/specifyjs prior to 0.2.136. This may lead to denial of service due to resource exhaustion. No network-based attack or privilege escalation is indicated.
Mitigation Recommendations
Upgrade to @asymmetric-effort/specifyjs version 0.2.136 or later, where data: URIs are limited to 1MB and larger URIs throw an error. This official fix effectively mitigates the vulnerability.
