Security vulnerabilities and automated fixes for golang x text issues
1 post found
CVE-2026-56852 is a high-severity Denial of Service vulnerability in the `golang.org/x/text` package where a `norm.Iter` iterator can enter an infinite loop when processing certain invalid UTF-8 input sequences. Applications using `golang.org/x/text` v0.37.0 or earlier that accept untrusted text input are at risk of complete service disruption. The fix is a one-line dependency bump in `go.mod` from v0.37.0 to v0.39.0.
