CVE-2026-33487 is a high-severity (CVSS 7.5) vulnerability impacting the goxmlsig library, specifically versions prior to 1.6.0, when used with Go versions before 1.22 or older `go.mod` configurations. This flaw, a loop variable capture issue in the `validateSignature` function, can lead to improper XML Digital Signature validation. A remote attacker could exploit this with low complexity to achieve a high integrity impact by bypassing security controls. There is no evidence of active exploitation, nor is public exploit code available, and community discussion remains minimal.
