OpenClaw: Unicode canonicalization drift in node metadata policy classification could broaden node allowlists

Summary A paired node could supply Unicode-confusable platform or deviceFamily metadata that passed metadata pinning but classified differently for command policy resolution, broadening default node command allowlists. Impact This is a policy-bypass issue within the paired-node trust boundary and...

Nokogiri does not check the return value from xmlC14NExecute

Summary Nokogiri's CRuby extension fails to check the return value from xmlC14NExecute in the method Nokogiri::XML::Documentcanonicalize and Nokogiri::XML::Nodecanonicalize. When canonicalization fails, an empty string is returned instead of raising an exception. This incorrect return value may...

Authentication Bypass

libxml2 is vulnerable to an Authentication Bypass. The vulnerability is due to a flaw in the XML canonicalization process used during transformations, which allows an attacker to reuse a previously generated valid signature to replay requests and bypass authentication checks...

CVE-2026-23831

Rekor is a software supply chain transparency log. In versions 1.4.3 and below, the entry implementation can panic on attacker-controlled input when canonicalizing a proposed entry with an empty spec.message, causing nil Pointer Dereference. Function validate returns nil success when message is...

Incorrect Behavior Order: Authorization Before Parsing and Canonicalization

Overview org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services. Affected versions of this package are vulnerable to Incorrect Behavior Order: Authorization Before Parsing and Canonicalization due to the Authorization header...

EUVD-2026-1461

A flaw was found in Keycloak. The Keycloak Authorization header parser is overly permissive regarding the formatting of the "Bearer" authentication scheme. It accepts non-standard characters such as tabs as separators and tolerates case variations that deviate from RFC 6750 specifications...
