CVE-2026-33487
goxmlsig provides XML Digital Signatures implemented in Go.
Published Mar 26, 2026 · corrected/updated Sep 9, 2026 · goxmldsig project goxmldsig · evidence confidence medium
goxmlsig provides XML Digital Signatures implemented in Go. Prior to version 1.6.0, the function in goes through the references in the block to find one that matches the signed element's ID. In Go versions before 1.22, or when uses an older version, there is a loop variable capture issue. The code takes the address of the loop variable instead of its value. As a result, if more than one reference matches the ID or if the loop logic is incorrect, the pointer will always end up pointing to the last element in the slice after the loop. goxmlsig version 1.6.0 contains a patch.
