CVE-2026-86258 nbviewer through 1.0.1 Path Traversal via LocalFileHandler

nbviewer through 1.0.1 contains a path traversal vulnerability in LocalFileHandler.canshow that uses string-prefix comparison instead of proper path validation. Attackers can read files from sibling directories outside the configured root by requesting paths that share the root as a textual prefi...

CVE-2026-86253

h3 npm package versions = 2.0.1-rc.14 contain a path traversal vulnerability in serveStatic. On Node.js deployments, event.url.pathname is not normalized, so percent-encoded dot segments %2e%2e are passed to decodeURI and decoded to ../ sequences without sanitization. An unauthenticated remote...

CVE-2026-86251

h3 versions before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. A double-decoding flaw allows a request path containing double-encoded dot sequences e.g. %252e%252e to be decoded to %2e%2e, which survives resolveDotSegments because that function only checks for litera...

CVE-2026-86253 h3 before 1.15.6 Path Traversal via Percent-Encoded Dot Segments

Arbitrary file read via workspace confinement bypass in local-operator /v1/chat/agents/{id}/edit

The /v1/chat/agents/agentid/edit endpoint in local-operator versions before 0.47.5 resolves the caller-supplied filepath with expanduser.resolve and reads it without checking that it lies inside the agent's workspace. An unauthenticated client with network access to the API can supply an absolute...
