CVE-2026-33916

Handlebars provides the power necessary to let users build semantic templates. In versions 4.0.0 through 4.7.8, resolvePartial in the Handlebars runtime resolves partial names via a plain property lookup on options.partials without guarding against prototype-chain traversal. When Object.prototype...

Eval Injection

Overview letta is a Create LLM agents with long-term memory and custom tools Affected versions of this package are vulnerable to Eval Injection via the resolvetype function. An attacker can execute arbitrary code by supplying crafted input that is improperly neutralized before being evaluated. No...

Handlebars.js has JavaScript Injection via AST Type Confusion when passing an object as dynamic partial

Summary A crafted object placed in the template context can bypass all conditional guards in resolvePartial and cause invokePartial to return undefined. The Handlebars runtime then treats the unresolved partial as a source that needs to be compiled, passing the crafted object to env.compile...

CVE-2026-33532

Summary: CVE-2026-33532 affects the yaml JavaScript library. The vulnerability is in the compose/resolve phase of the parser, where a recursive call path without a depth bound can cause a RangeError: Maximum call stack size exceeded when parsing YAML input (typical payload ~2–10 KB). This can lea...

GHSA-72GR-QFP7-VWHW h3: Double Decoding in `serveStatic` Bypasses `resolveDotSegments` Path Traversal Protection via `%252e%252e`

Summary The serveStatic utility in h3 applies a redundant decodeURI call to the request pathname after H3Event has already performed percent-decoding with %25 preservation. This double decoding converts %252e%252e into %2e%2e, which bypasses resolveDotSegments since it checks for literal...
