GHSA-cqxr-jxr2-85pq: github.com/tomwright/dasel/v3 (CVE-2026-59168)

Package	Ecosystem	Affected	Fixed in
github.com/tomwright/dasel/v3	Go	>=3.0.0, <3.11.1	3.11.1

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Dasel v3 versions from 3.0.0 up to but not including 3.11.1 are vulnerable. The JSON and XML readers recurse without a nesting-depth limit, so a small, deeply nested document causes an unrecoverable Go stack overflow that terminates the whole process. An attacker who can supply JSON or XML to dasel, through the library, the CLI, or the parse selector, can trigger this denial of service with one document, and no confidentiality or integrity impact is stated. Upgrade to version 3.11.1.
