    Moov signedxml: Unauthenticated denial of service in exclusive XML canonicalization

    CVE-2026-113729 · GHSA-5588-rp99-5fjh

    Affected
    • Go github.com/moov-io/signedxml <= 1.4.0
    Fixed in
    1.4.1· Vendor fix available
    Issue
    Exclusive XML canonicalization (http://www.w3.org/2001/10/xml-exc-c14n#) in github.com/moov-io/signedxml copied the entire accumulated namespace map at every node during ValidateReferences(), before any reference digest or signature check. For a chain of nested elements that each declare many unused namespace prefixes, that produced O(m × depth²) time and peak memory (m = prefixes per level). beevik/etree caps tree depth (~1024), but m is unbounded, so a small attacker-controlled document (on the order of 1 MB) could drive multi-gigabyte allocations and OOM the process. No valid signature, matching certificate, or authentication is required. This is the library’s core path for SAML / WS-Federation service providers, which canonicalize attacker-supplied XML prior to authentication. Affected - Package: github.com/moov-io/signedxml - Function: ExclusiveCanonicalization (exclusivecanonicalization.go) - Verified: v1.4.0 and current default branch (commit d79064a). Earlier v1.2.x–v1.3.x…

    Recommended action: Upgrade to 1.4.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.

    Signature validation bypass in github.com/moov-io/signedxml

    CVE-2023-34205 · GHSA-jqvr-j2vg-gjrv

    Affected
    • Go github.com/moov-io/signedxml < 1.1.0
    Fixed in
    1.1.0· Vendor fix available
    Issue
    In Moov signedxml through 1.0.0, parsing the raw XML (as received) can result in different output than parsing the canonicalized XML. Thus, signature validation can be bypassed via a Signature Wrapping attack (aka XSW).

    Recommended action: Upgrade to 1.1.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
