fix(deps): pin AngleSharp to 1.5.2 to clear mXSS advisory#106
Merged
Conversation
bUnit -> AngleSharp.Diffing pulls AngleSharp 1.4.0 transitively, which has a moderate mXSS advisory (GHSA-pgww-w46g-26qg / CVE-2026-54570) patched in 1.5.0. The CI vulnerability gate fails on any severity, so this blocks the build. Enable central transitive pinning and pin AngleSharp to the patched 1.5.2 (latest stable). Verified: vuln scan clean across all projects, Blazor bUnit suite 102/102 green.

Problem
bunit 2.7.2pulls AngleSharp 1.4.0 transitively (viaAngleSharp.Diffing) into the Blazor test project. That version has a moderate mXSS advisory — GHSA-pgww-w46g-26qg / CVE-2026-54570 (improper MathML<annotation-xml>handling, sanitizer bypass), patched in 1.5.0.The CI vulnerability gate (
.github/workflows/ci.yml) fails on any severity, so this blocks the build rather than just warning.Fix
Enable central transitive pinning and pin AngleSharp to the patched 1.5.2 (latest stable; 1.5.3 is prerelease-only). No direct
