Updates the requirements on robrichards/xmlseclibs to permit the latest version.

Release notes

Sourced from robrichards/xmlseclibs's releases.

4.0.1

Harden HMAC key loading so asymmetric material cannot be used as an HMAC secret. The same check applies when signing or verifying. Ordinary HMAC secrets still load.

xmlseclibs.php ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 19, Oct 2026, 4.0.1 Security Improvements:

• Harden HMAC key loading so asymmetric material cannot be used as an HMAC secret. The same check applies when signing or verifying. Ordinary HMAC secrets still load.

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 22, Aug 2026, 4.0.0 Features:

• Add reference option omit_uri to skip adding a URI attribute on Reference (also skips Id assignment on the referenced element, which exists only to support the URI fragment)
• Change selected XMLSecurityDSig private properties and methods to protected so the class can be extended (gdespirito). refs #152
• Add XMLSecurityDSig::ENVELOPED constant for the enveloped-signature Transform URI; deprecate empty appendCert() stub (use add509Cert())

Security Improvements:

• Harden add509Cert() URL fetching against SSRF: only http/https by default (file:// requires options['allow_file_scheme']); resolve the host and reject loopback/private/link-local/reserved/CGNAT addresses; disable HTTP redirects
• Reject IPv4-mapped / IPv4-compatible IPv6 certificate URL hosts (e.g. ::ffff:127.0.0.1, ::ffff:169.254.169.254): unwrap the embedded IPv4 and apply the same private/reserved/CGNAT checks (PHP's FILTER_FLAG_NO_* treats mapped addresses as public)
• Fail closed on unknown Reference Transform algorithms; recognize enveloped-signature explicitly. validateReference() no longer always detaches the Signature from the caller DOM (that broke C14N of ds:Object targets and left half-mutated trees on failure); enveloped-signature removes Signature only when it is a proper descendant of the node being digested
• Tighten same-document Reference URIs to empty URI and "#id" only (reject "?query", bare "#", and external URIs); share parsing between processRefNode() and getRefNodeID(). Same-document refs always omit comments
• Reject hostile idKeys attribute names (no whitespace / XPath operators) via Utils\XPath::filterAttrName; invalid names throw
• Reject duplicate CanonicalizationMethod / SignatureMethod under SignedInfo and duplicate DigestMethod / DigestValue / SignatureValue during verify
• Reset the cached DOMXPath in locateSignature() so instance reuse across documents cannot fatal with "Node from wrong document"
• verifyDocument() no longer permanently overwrites instance algorithm allowlists (restored in finally)
• addReference() / addReferenceList() / sign() / add509Cert() throw instead of silently no-oping when SignedInfo / signature context is missing; sign() requires setCanonicalMethod() and a SignatureMethod element
• Require correct namespace URIs for InclusiveNamespaces (exc-c14n) and XPath transform children (not localName alone)
• Reject a DOCTYPE in decrypted XML (defense against entity-expansion / XXE in attacker-crafted encrypted content)
