An update for nodejs-underscore is now available for openEuler-24.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-1578 Final 1.0 1.0 2026-03-15 Initial 2026-03-15 2026-03-15 openEuler SA Tool V1.0 2026-03-15 nodejs-underscore security update An update for nodejs-underscore is now available for openEuler-24.03-LTS-SP2 Underscore.js is a utility-belt library for JavaScript that provides support for the usual functional suspects (each, map, reduce, filter...) without extending any core JavaScript objects. Security Fix(es): Underscore.js is a utility-belt library for JavaScript. Prior to version 1.13.8, the `_.flatten` and `_.isEqual` functions use recursion without a depth limit. Under very specific conditions, an attacker could exploit this to cause a Denial of Service (DoS) attack by triggering a stack overflow. Exploitation requires all of the following: untrusted input must be used to create a deeply recursive data structure (e.g., via `JSON.parse` with no enforced depth limit), and this structure must be passed to `_.flatten` or `_.isEqual`. For `_.flatten`, the attacker must be able to prepare a data structure consisting solely of arrays at all levels, and no finite depth limit must be passed as the second argument to `_.flatten`. For `_.isEqual`, there must exist a code path where two distinct but structurally equivalent data structures, submitted by the same remote client, are compared using `_.isEqual`. Additionally, exceptions resulting from the stack overflow must not be caught. This vulnerability is fixed in version 1.13.8.(CVE-2026-27601) An update for nodejs-underscore is now available for master/openEuler-20.03-LTS-SP4/openEuler-22.03-LTS-SP4/openEuler-24.03-LTS-SP2. openEuler Security has rated this update as having a security impact of high.
