CVSS 3.1
5.6 mediumCVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:LCVE-2020-29509
Medium (5.6). EPSS 2.1% chance of exploitation in the next 30 days. Fixed in github.com/russellhaering/gosaml2 0.6.0.
The encoding/xml package in Go (all versions) does not correctly preserve the semantics of attribute namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.
