SCA: security update for go.opentelemetry.io/otel/sdk (GHSA-p9f8-wvj8-2fg8)
medium Tenable Cloud Security Plugin ID 448473
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 1.10.0 until 1.33.0, the
sdk/trace/span.go attribute truncation path can fail to enforce AttributeValueLengthLimit for string and
string-slice attributes containing the valid Unicode replacement character U+FFFD. safeTruncateValidUTF8
treats the valid replacement rune as invalid UTF-8 and returns the original input, while
strings.ToValidUTF8 leaves that valid rune unchanged, so a second safeTruncate attempt can also return the
oversized value. An attacker who controls span attribute content can retain values longer than the
configured limit, increasing per-span memory use and weakening denial-of-service protection in the
instrumented process. This issue is fixed in version 1.33.0. (CVE-2026-81869)
Solution
Update the go.opentelemetry.io/otel/sdk library and its related packages to version 1.33.0 or later.See Also
